  • Remote Desktop failed logon event 4625 not logging correctly on 2008 Terminal Services server

    - by Zone12
    When I use the new remote desktop with ssl and try to log on with bad credentials it logs a 4625 event as expected. The problem is, it doesn't log the ip address, so I can't block malicious logons in our firewall. The event looks like this: <Event xmlns="http://schemas.microsoft.com/win/2004/08/events/event"> <System> <Provider Name="Microsoft-Windows-Security-Auditing" Guid="{00000000-0000-0000-0000-000000000000}" /> <EventID>4625</EventID> <Version>0</Version> <Level>0</Level> <Task>12544</Task> <Opcode>0</Opcode> <Keywords>0x8010000000000000</Keywords> <TimeCreated SystemTime="2012-04-13T06:52:36.499113600Z" /> <EventRecordID>467553</EventRecordID> <Correlation /> <Execution ProcessID="544" ThreadID="596" /> <Channel>Security</Channel> <Computer>ontheinternet</Computer> <Security /> </System> <EventData> <Data Name="SubjectUserSid">S-1-0-0</Data> <Data Name="SubjectUserName">-</Data> <Data Name="SubjectDomainName">-</Data> <Data Name="SubjectLogonId">0x0</Data> <Data Name="TargetUserSid">S-1-0-0</Data> <Data Name="TargetUserName">notauser</Data> <Data Name="TargetDomainName">MYSERVER-PC</Data> <Data Name="Status">0xc000006d</Data> <Data Name="FailureReason">%%2313</Data> <Data Name="SubStatus">0xc0000064</Data> <Data Name="LogonType">3</Data> <Data Name="LogonProcessName">NtLmSsp</Data> <Data Name="AuthenticationPackageName">NTLM</Data> <Data Name="WorkstationName">MYSERVER-PC</Data> <Data Name="TransmittedServices">-</Data> <Data Name="LmPackageName">-</Data> <Data Name="KeyLength">0</Data> <Data Name="ProcessId">0x0</Data> <Data Name="ProcessName">-</Data> <Data Name="IpAddress">-</Data> <Data Name="IpPort">-</Data> </EventData> </Event> It seems because the logon type is 3 and not 10 like the old rdp sessions, the ip address and other information is not stored. The machine I am trying to connect from is on the internet and not on the same network as the server. Does anyone know where this information is stored (and what other events are generated with a failed logon)? Any help will be much appreciated.

  • Duplicate DNS Zones (Error 4515 in Event Log )

    - by Campo
    I am getting these two error in the DNS Event log (errors at end of question). I have confirmed I do have duplicate zones. I am wondering which ones to delete. The DomainDNSZone contains all of our DNS records but it does not have the _msdcs zone.... that is in the ForestDNSZone with the duplicates that are not in use. here is a picture of that 3 Questions. I understand the advantages of having DNS in the ForestDNSZone. so... Why is DNS using the DomainDNSZone and is that acceptable considering _msdcs... is in the ForestDNSZone? If so, should I just delete the DC=1.168.192.in-addr.arpa and DC=supernova.local from the ForestDNSZone? Or should I try to get those to be the ones in use? What are those steps? I understand how to delete. That is simple but if i must move zones some info would be appreaciated there. Just to confirm. from my understanding. I can delete the two duplicates in the ForestDNSZone and leave the _msdcs.supernova.local as thats required there. This will resolve the erros I see. Just fyi when I look in those folders from the ForestDNSZone they have just 2 and 1 entries respectively. So obviously not in use compared to the others. I am pretty sure I understand the steps to complete this. But if you would like to provide that info, bonus points!

If an administrator has moved this zone from one directory partition to another this may be a harmless transient condition. In this case, no action is necessary.

  • Windows Server 2012 Migration (DNS/AD DS Standard Eval to Essentials OEM) P2V -> Do I need a Secondary Domain Controller during migration?

    - by Aubrey Robertson
    This is my first post on this exchange (although not my first on stack exchange), so please have patience. I am a 3rd year student intern, and I have been tasked with virtualizing the server systems at the company I work for. I have come a long way, and I am almost ready to install the VM Server in migration mode. Here is some information: Source Server: Windows Server 2012 Standard Evaluation DNS Server (local only) Advanced Directory Domain Services File and Storage stuff A few other server roles Destination Server: Windows Server 2012 Essentials OEM (Hyper-V client) Running under a temporary Hyper-V host (will migrate the Hyper-V host back to the old machine after the original server is virtualized as a client). Sitting currently at the "Select Installation Mode" screen. I have been following the guides on Microsoft tech net, and today I spent most of the day getting rid of issues in the Best Practices Analyser on the source machine. I have 3 remaining issues (which are all related): ERROR: DNS: DNS servers on Ethernet (adapter name) should include the loopback address, but not as the first entry (flavour text indicates that, during migration, the DNS server may not be found) WARNING: All domains should have at least two domain controllers for redundancy. WARNING: DNS: Ethernet should be configured to use both a preferred and an alternate DNS Server. All of these issues can be resolved by deploying a secondary domain controller, but I have never done that before (see my concerns below). The main issue here that I am concerned with for installing in migration mode is the FIRST one (the error). If I try and set-up the new server deployment, and the adapter domain controller is listed as localhost, then this may cause the installation to fail. (at least, this is what the Microsoft documentation suggests). But I do not have another IP address to enter here as I have no other local domain controllers. So I did the first obvious thing that came to my mind, and tried to use Google DNS servers as my alternates. That did not work because they couldn't recognize other computers in the "forest". Now I'm no expert when it comes to DNS, so please forgive my ignorance. This DNS server is concerned only with Active Directory stuffs for the local network. If I go ahead with migration, and it fails, then I will just have to go ahead and install a secondary DNS server I suppose. The problem I have here is that I am limited by the amount of Windows Server keys I have available (I have 2); however, I do have access to a Linux box running Debian Wheezy that I set-up two weeks ago as a Mantis server. I could install Windows Server 2012 as a secondary DNS (I think) in a VM and use that, but then it seems like I will be wasting time, and probably the Windows key too, and if there's another way to do it with Linux that would be much better. Even better still, do I even need a secondary DNS server for migration at all? The hints said that during migration the original machine "might" not be found. Thank you for your time and consideration.

  • Application Does Not Start in Windows 7

    - by Jim Fell
    I recently installed a new 60GB SSD as my primary hard drive and re-installed Windows 7 Professional 64-bit. I then installed SSD Fresh from Abelssoft to optimize Windows to run on the SSD. It seemed to install okay, but when I try to run the utility, its splash screen appears briefly before it quietly closes. No errors are displayed; the utility just fails to launch. I have run SSD Fresh on another SSD-equipped Windows 7 Pro x64 computer in the past without any problems. Does anyone know what might be preventing the program from running? I tried running sfc /scannow from the command line (with administrator privileges), shutting down the Spybot Resident, and disabling the firewall and virus scanner. I also tried running the tool as administrator; I even tried reinstalling it, running the installer as administrator. No luck. Every time I try to launch the program the Event Viewer logs this same set of errors: Error 4/2/2012 11:35:44 PM Application Error 1000 (100) Faulting application name: SSDFresh.exe, version: 1.0.0.0, time stamp: 0x4f2a45d8 Faulting module name: unknown, version: 0.0.0.0, time stamp: 0x00000000 Exception code: 0xc0000005 Fault offset: 0x000007ff0016dbba Faulting process id: 0x994 Faulting application start time: 0x01cd11fd9fe978df Faulting application path: C:\Program Files (x86)\SSD Fresh\SSDFresh.exe Faulting module path: unknown Report Id: dfeed551-7df0-11e1-a2c7-002522c47ec0 Error 4/2/2012 11:35:43 PM .NET Runtime 1026 None Application: SSDFresh.exe Framework Version: v4.0.30319 Description: The process was terminated due to an unhandled exception.

  • OpenVPN on Tomato and Vista - can't see my network

    - by Ian
    I followed the instructions here (http://todayguesswhat.blogspot.ca/2011/03/quick-simple-vpn-setup-guide-using.html) to set up a TCP connection to OpenVPN on my Tomato router. Used TCP because the place I usually surf at seems to have the other ports blocked. My Vista laptop is able to connect to the router but I don't appear to be getting an IP address. I'm able to access my router's admin page, but I can't see the network at home. When I browse to Whatsmyip I see my home IP. Here are the results of route print -4 when I'm just connect to the library and when I've fired up the VP connection as well: Library only: =========================================================================== Interface List 22 ...00 ff c4 a0 e7 5c ......

  • SNTP, why do you mock me?!

    - by Matthew
    --- SOLVED SEE EDIT 5 --- My w2k3 pdc is configured as an authoritative time server. Other servers on the domain are able to sync with it if I manually specify it in the peer list. By if I try to sync from flags 'domhier', it wont resync; I get the error message The computer did not resync because no time data was available. I can only think that it is not querying the pdc. I also tried setting the registry as shown here (http://support.microsoft.com/kb/193825). But no luck (I have not restarted the server, I am hoping I wont have to since it is the pdc) If you would like any further information on my config, please let me know. Edit 1: I have set the w32time service config AnnouceFlags to 0x05 as documented here www.krr.org/microsoft/authoritative_time_servers.php and a number of other places. The PDC syncs to an external time source (ntp). I can get the stripchart on the client from the pdc no problems. The loginserver for the host I am trying to configure is shown as the pdc. Edit 2: The packet capture has revealed something interesting. The client is contacting the correct server, and getting a valid response but I still get the same error message. Here is the NTP excerpt from the client to the server Flags: 11.. .... = Leap Indicator: alarm condition (clock not synchronized) (3) ..01 1... = Version number: NTP Version 3 (3) .... .011 = Mode: client (3) Peer Clock Stratum: unspecified or unavailable (0) Peer Polling Interval: 10 (1024 sec) Peer Clock Precision: 0.015625 sec Root Delay: 0.0000 sec Root Dispersion: 1.0156 sec Reference Clock ID: NULL Reference Clock Update Time: Sep 1, 2010 05:29:39.8170 UTC Originate Time Stamp: NULL Receive Time Stamp: NULL Transmit Time Stamp: Nov 8, 2010 01:44:44.1450 UTC Key ID: DC080000 Here is the reply NTP excerpt from the server to the client Flags: 0x1c 00.. .... = Leap Indicator: no warning (0) ..01 1... = Version number: NTP Version 3 (3) .... .100 = Mode: server (4) Peer Clock Stratum: secondary reference (3) Peer Polling Interval: 10 (1024 sec) Peer Clock Precision: 0.00001 sec Root Delay: 0.1484 sec Root Dispersion: 0.1060 sec Reference Clock ID: 192.189.54.17 Reference Clock Update Time: Nov 8,2010 01:18:04.6223 UTC Originate Time Stamp: Nov 8, 2010 01:44:44.1450 UTC Receive Time Stamp: Nov 8, 2010 01:46:44.1975 UTC Transmit Time Stamp: Nov 8, 2010 01:46:44.1975 UTC Key ID: 00000000 Edit 3: dumpreg for paramters on pdc Value Name Value Type Value Data ------------------------------------------------------------------------ ServiceMain REG_SZ SvchostEntry_W32Time ServiceDll REG_EXPAND_SZ C:\WINDOWS\system32\w32time.dll NtpServer REG_SZ bhvmmgt01.domain.com,0x1 Type REG_SZ AllSync and config Value Name Value Type Value Data -------------------------------------------------------------------------- LastClockRate REG_DWORD 156249 MinClockRate REG_DWORD 155860 MaxClockRate REG_DWORD 156640 FrequencyCorrectRate REG_DWORD 4 PollAdjustFactor REG_DWORD 5 LargePhaseOffset REG_DWORD 50000000 SpikeWatchPeriod REG_DWORD 900 HoldPeriod REG_DWORD 5 LocalClockDispersion REG_DWORD 10 EventLogFlags REG_DWORD 2 PhaseCorrectRate REG_DWORD 7 MinPollInterval REG_DWORD 6 MaxPollInterval REG_DWORD 10 UpdateInterval REG_DWORD 100 MaxNegPhaseCorrection REG_DWORD -1 MaxPosPhaseCorrection REG_DWORD -1 AnnounceFlags REG_DWORD 5 MaxAllowedPhaseOffset REG_DWORD 300 FileLogSize REG_DWORD 10000000 FileLogName REG_SZ C:\Windows\Temp\w32time.log FileLogEntries REG_SZ 0-300 Edit 4: Here are some notables from the ntp log file on the pdc.

Ok so I was reading about people with similar problems, some mentioned w32time server settings applied by GPO, but I tested this early on and there were no settings applied to this service by gpo. Others said that the reporting software may not be picking up some old gpo settings applied. So I searched the registry for all w32time instaces. I came across an interesting key that indicated there may be some other ntp software running on the server. Sure enough, I look through the installed software list and there the little F*&%ER is. Uninstalled and now working like a dream. FFFFFFFUUUUUUUUUUUU

  • Looking for advice on Hyper-v storage replication

    - by Notre1
    I am designing a 2-host Hyper-V R2 cluster with 6-10 guests stored on a SMB iSCSI SAN device (probably Promise VessRAID). I will be getting at least two of the SAN devices and need to eliminate the storage a single point of failure. Ideally, that would involve real-time failover for the storage, like the Windows failover clustering does for the hosts. This design will be used at around six of our sites, and I would like to allow for us to eventually setup a cluster at colocation site and replicate each site's VMs there for DR. (Ideally a live multi-site cluster, but a manual import of the VMs would be fine for this sort of DR.) The tools that come with enterprise SANs, like EMC and NetApp, seem to be the most commonly used items for a Hyper-V cluster, but I can't afford their prices with my budget. Outside of them, the two tools that seem to be most common for Hyper-V storage replication are SteelEye (now SIOS) DataKeeper Cluster Edition and Double-Take Availability. Originally, I was planning on using Clustered Shared Volume(s) (CSV), but it seems like replication support for these is either not available or brand new in both these products. It looks like CSVs are supported in Double-Take 5.22, see this discussion, but I don't think I want to run something that new in production. Right now, it seems like the best option for me is not to implement CSVs, implement some sort of storage replication, and upgrade to CSVs at a later date once replicating them is more mature. I would love to have live migration, and CSVs are not required for live migration if you are using one LUN per VM, so I guess this is what I'll do. I would prefer to stick to the using the Microsoft Windows Server and Hyper-V tools and features as much as possible. From that standpoint, SteelEye looks more appealing than Double-Take because they make the DataKeeper volume(s) available to the Failover Clustering Manager and then failover clustering is all configured and managed through the native Microsoft tools. Double-Take says that "clustered Hyper-V hosts are not supported," and Double-Take Availability itself seems to be what is used for the actual clustering and failover. Does anyone know if any of these replication tools work with more than two hosts in the cluster? All the information I can find on the web only uses two hosts in their examples. Are there any better tools than SteelEye and Double-Take for doing what I am trying to do, which is eliminate the storage as as single point of failure? Neverfail, AppAssure, and DataCore all seem to offer similar functionality, but they don't seems to be as popular as SteelEye and Double-Take. I have seen a number of people suggest using Starwind iSCSI SAN software for the shared storage, which includes replication (and CSV replication at that). There are a couple of reasons I have not seriously considered this route: 1) The company I work for is exclusively a Dell shop and Dell does not have any servers with that I can pack with more than six 3.5" SATA drives. 2) In the future, it could be advantegous for us to not be locked into a particular brand or type of storage and third-party replication softwares all allow replication to heterogeneous storage devices. I am pretty new to iSCSI and clustering, so please let me know if it looks like I am planning something that goes against best practices or overlooking/missing something.

  • Just a few questions about Hyper-V virtual machines and clustering

    - by René Kåbis
    I have been using Microsoft’s Hyper-V technology for a little while now, but I am just now dipping my toe into clustering. In particular, I am trying to implement a fault-tolerant SQL DB. This involves setting up two VMs, clustering them via Failover Cluster, and then installing SQL Server in some fashion. I have two physical machines - one high-end and rather beefy “heavy lifter” to contain the majority of the VMs, and another “backup” (a repurposed desktop) to hold the essential “secondary” (or failover) AD-DC, SQL and FS VMs. The main reason why I find the failover cluster at the VM level so attractive is that it presents a single IP and DNS entry to the network as a whole - if one machine (physical or virtual) goes down, you might loose some ping and the connections get reset, but the network applications (Microsoft RMS connection to backend SQL) can still connect to a viable DB without having to mess around with the settings at all. My first question is in terms of SQL Server itself. If I have a cluster between two VMs, does it make more sense to install the SQL Server in Failover Cluster configuration or should I simply install it in a stand-alone config and mirror the DBs? For example, this post suggests just mirroring the DBs, but do I just mirror standalone DBs on standalone VMs, or can I get the network and failover benefits of clustered VMs while still utilizing (on each clustered VM) standalone DBs that have been mirrored between each other? As well, I have come across a lot of documentation about SQL clustering, but most assume a number (#2) of physical machines to hold not only the actual SQL VMs but also the Quorum and Witness stores. I will not be able to muster more than two physical machines. As such, I will have to be satisfied with a VM cluster that does not exceed two VMs (one for each physical machine). Another issue involves MSDTC - the Distributed Transaction Coordinator. When attempting to install the SQL Failover Cluster (I never completed it for this reason) it threw a hissy fit because MSDTC had not been clustered. Search as I might, I have not yet found a way to do so under Windows Server 2012 R2. I have found plenty of docs for Windows 2008 and 2008 R2, but these instructions don’t align with 2012 R2 (at least, not in a way that allows me to successfully cluster MSDTC). Plus, some of the instructions that I have found for SQL Server Failover Cluster installation suggest that a third “network device” - shared network storage (a SAN) - is required for the DB itself (and other functionality). I do not have this, and won’t be getting this. Most of my storage exists on the “heavy lifter” that was designed for all of the “primary” VMs. If that physical machine goes down, so does the storage. The secondary server does have enough resources for an AD-DC Server, an SQL server and a File Server, so it will handle the “secondary” failover versions of those VMs (clustered or not). My final question involves file servers. If I cluster file servers between two VMs (one on my “heavy lifter” and another on my “backup”, how do I mirror the data between them? Clustering VMs only provides a single point of access on the network for a resource, it doesn’t exactly replicate data between the two - that is left to the services that serve up that data. I am unsure how I can ensure that file server data between two clustered file server VMs can be properly mirrored. Remember, I only have two devices to be used here - my primary machine and a backup secondary. There is no chance of me obtaining a SAN or any other type of network attached storage. What exists on the machines must act as the storage. Thanks in advance for any suggestions.

  • Installation of Access Database Engine 32-bit Fails

    - by Rayzor78
    I am trying to install Access Database Engine 2007 32-bit. The splash screen comes up, you click "Next", then it fails with the error: Installation ended prematurely because of an error You click "OK" and another error window says: The installation of the package failed. The exact same situation happens when I try this with Access Database Engine 2010 32-bit. This production server is running Windows Server 2008 R2 SP1 64-bit. Before I tried installing Access Database Engine 32-bit, I first needed to install Microsoft Office 2010 Pro (Excel and Office Tools only). I tried the 32-bit version on the production server since that is how I set it up in our Dev environment. No luck. The 32-bit version would not install. I did NOT get the error "You have 64-bit components of Office installed". I simply received the exact same two errors listed above. So, I knew that 32-bit/64-bit did not really matter for the Office install for my project, so I installed 64-bit of Office Pro 2010 (Excel and Office Tools only) with no problems. I have a requirement that I need to have the 32-bit version of the Access Database Engine installed. 2007 or 2010, doesn't matter. I cannot use the 64-bit version of Access Database Engine 2010 because my SSIS package will not work with it. I require the 32-bit version. I've tried several steps to try to get it installed. I seriously think that the production server has some aversion to installing 32-bit applications. Here's what I've tried: Tried installing via command line with the "/passive" switch....no luck. Tried numerous iterations to copy the install file to the server (downloaded a fresh copy directly to the server, downloaded a fresh copy to my local machine then copied it over, copied it over zipped up) (http://social.msdn.microsoft.com/Forums/en-US/sqldataaccess/thread/efd3c1f0-07cd-45ca-a626-2dd0c7ac3e9f). Tried Method 1 from this link. Could not try Method 2 because it requires a server reboot and in my environment that requires a long change management process. I've verified that I am a local administrator on the server. (Evidence, I am able to install other applications (office 64-bit per above)). Verified that there are no other office products that should be blocking the installation. The fore-mentioned install of Excel 2010 64-bit was the first Office product installed on the server. VERY ODD: To test my theory that the production server does not like 32-bit applications, I installed something lightweight. I installed 7-Zip 32-bit on the production server with no problems whatsoever. Here are some things that I have not tried (i will follow-up once I do): Method 2 (as mentioned above). Requires a server reboot. Have not verified that the Dev and Production environments are 100% identical. I've done a cursory check and on the surface they appear to be the same (same OS and SP version). I need to do a deeper dive to be 100% certain. I had no problems in my Dev environment. In Dev, I installed Office 2010 Pro 64-bit (Excel & Office Tools only) then via command line w/ the "/passive" switch, installed Access Database Engine 2010 32-bit. I don't know what else to try. Any suggestions or comments?

  • AMD Catalyst 13.9 installation failure

    - by Simon Verbeke
    Earlier today I installed Windows 8.1, and when I wanted to go into Catalyst Control Center, I noticed some odd error of CCC not being able to display options. I then figured I needed a driver update, so I downloaded the latest drivers, version 13.9, and tried to install them. While it was trying to install the display drivers, I got a blue screen. Tried again and got the same. Then I used an uninstall tool from AMD to remove all traces of my old drivers and tried to install the new drivers. Again, a blue screen. This is all I could think of to try. Would anyone know some other things I can try? EDIT: thought I might want to include the log entry for the crash: - <Event xmlns="http://schemas.microsoft.com/win/2004/08/events/event"> - <System> <Provider Name="Microsoft-Windows-WER-SystemErrorReporting" Guid="{ABCE23E7-DE45-4366-8631-84FA6C525952}" EventSourceName="BugCheck" /> <EventID Qualifiers="16384">1001</EventID> <Version>0</Version> <Level>2</Level> <Task>0</Task> <Opcode>0</Opcode> <Keywords>0x80000000000000</Keywords> <TimeCreated SystemTime="2013-10-19T20:59:25.000000000Z" /> <EventRecordID>26587</EventRecordID> <Correlation /> <Execution ProcessID="0" ThreadID="0" /> <Channel>System</Channel> <Computer>Simon-PC</Computer> <Security /> </System> - <EventData> <Data Name="param1">0x0000007e (0xffffffffc0000005, 0xfffff80002a86dca, 0xffffd00025f250e8, 0xffffd00025f248f0)</Data> <Data Name="param2">C:\WINDOWS\MEMORY.DMP</Data> <Data Name="param3">101913-8953-01</Data> </EventData> </Event> Another edit: As it turns out, the graphics card isn't showing up any more in the device manager. But as far as I can tell, it is still working (the fans are spinning and my screen is plugged into that graphics card). This is solved. it appears that my graphics card is now running with a default windows driver. I also tried the forced method mentioned here: AMD Graphics Drivers won't install properly . But I still get a BSOD. Third edit: Slight succes! Managed to install version 13.4. Everything appears to be working fine now. I think I'm just going to skip version 13.9.

  • Looking for advice on Hyper-v storage replication

    - by Notre1
    I am designing a 2-host Hyper-V R2 cluster with 6-10 guests stored on a SMB iSCSI SAN device (probably Promise VessRAID). I will be getting at least two of the SAN devices and need to eliminate the storage a single point of failure. Ideally, that would involve real-time failover for the storage, like the Windows failover clustering does for the hosts. This design will be used at around six of our sites, and I would like to allow for us to eventually setup a cluster at colocation site and replicate each site's VMs there for DR. (Ideally a live multi-site cluster, but a manual import of the VMs would be fine for this sort of DR.) The tools that come with enterprise SANs, like EMC and NetApp, seem to be the most commonly used items for a Hyper-V cluster, but I can't afford their prices with my budget. Outside of them, the two tools that seem to be most common for Hyper-V storage replication are SteelEye (now SIOS) DataKeeper Cluster Edition and Double-Take Availability. Originally, I was planning on using Clustered Shared Volume(s) (CSV), but it seems like replication support for these is either not available or brand new in both these products. It looks like CSVs are supported in Double-Take 5.22, see this discussion, but I don't think I want to run something that new in production. Right now, it seems like the best option for me is not to implement CSVs, implement some sort of storage replication, and upgrade to CSVs at a later date once replicating them is more mature. I would love to have live migration, and CSVs are not required for live migration if you are using one LUN per VM, so I guess this is what I'll do. I would prefer to stick to the using the Microsoft Windows Server and Hyper-V tools and features as much as possible. From that standpoint, SteelEye looks more appealing than Double-Take because they make the DataKeeper volume(s) available to the Failover Clustering Manager and then failover clustering is all configured and managed through the native Microsoft tools. Double-Take says that "clustered Hyper-V hosts are not supported," and Double-Take Availability itself seems to be what is used for the actual clustering and failover. Does anyone know if any of these replication tools work with more than two hosts in the cluster? All the information I can find on the web only uses two hosts in their examples. Are there any better tools than SteelEye and Double-Take for doing what I am trying to do, which is eliminate the storage as as single point of failure? Neverfail, AppAssure, and DataCore all seem to offer similar functionality, but they don't seems to be as popular as SteelEye and Double-Take. I have seen a number of people suggest using Starwind iSCSI SAN software for the shared storage, which includes replication (and CSV replication at that). There are a couple of reasons I have not seriously considered this route: 1) The company I work for is exclusively a Dell shop and Dell does not have any servers with that I can pack with more than six 3.5" SATA drives. 2) In the future, it could be advantegous for us to not be locked into a particular brand or type of storage and third-party replication softwares all allow replication to heterogeneous storage devices. I am pretty new to iSCSI and clustering, so please let me know if it looks like I am planning something that goes against best practices or overlooking/missing something.

  • Distributed and/or Parallel SSIS processing

    - by Jeff
    Background: Our company hosts SaaS DSS applications, where clients provide us data Daily and/or Weekly, which we process & merge into their existing database. During business hours, load in the servers are pretty minimal as it's mostly users running simple pre-defined queries via the website, or running drill-through reports that mostly hit the SSAS OLAP cube. I manage the IT Operations Team, and so far this has presented an interesting "scaling" issue for us. For our daily-refreshed clients, the server is only "busy" for about 4-6 hrs at night. For our weekly-refresh clients, the server is only "busy" for maybe 8-10 hrs per week! We've done our best to use some simple methods of distributing the load by spreading the daily clients evenly among the servers such that we're not trying to process daily clients back-to-back over night. But long-term this scaling strategy creates two notable issues. First, it's going to consume a pretty immense amount of hardware that sits idle for large periods of time. Second, it takes significant Production Support over-head to basically "schedule" the ETL such that they don't over-lap, and move clients/schedules around if they out-grow the resources on a particular server or allocated time-slot. As the title would imply, one option we've tried is running multiple SSIS packages in parallel, but in most cases this has yielded VERY inconsistent results. The most common failures are DTExec, SQL, and SSAS fighting for physical memory and throwing out-of-memory errors, and ETLs running 3,4,5x longer than expected. So from my practical experience thus far, it seems like running multiple ETL packages on the same hardware isn't a good idea, but I can't be the first person that doesn't want to scale multiple ETLs around manual scheduling, and sequential processing. One option we've considered is virtualizing the servers, which obviously doesn't give you any additional resources, but moves the resource contention onto the hypervisor, which (from my experience) seems to manage simultaneous CPU/RAM/Disk I/O a little more gracefully than letting DTExec, SQL, and SSAS battle it out within Windows. Question to the forum: So my question to the forum is, are we missing something obvious here? Are there tools out there that can help manage running multiple SSIS packages on the same hardware? Would it be more "efficient" in terms of parallel execution if instead of running DTExec, SQL, and SSAS same machine (with every machine running that configuration), we run in pairs of three machines with SSIS running on one machine, SQL on another, and SSAS on a third? Obviously that would only make sense if we could process more than the three ETL we were able to process on the machine independently. Another option we've considered is completely re-architecting our SSIS package to have one "master" package for all clients that attempts to intelligently chose a server based off how "busy" it already is in terms of CPU/Memory/Disk utilization, but that would be a herculean effort, and seems like we're trying to reinvent something that you would think someone would sell (although I haven't had any luck finding it). So in summary, are we missing an obvious solution for this, and does anyone know if any tools (for free or for purchase, doesn't matter) that facilitate running multiple SSIS ETL packages in parallel and on multiple servers? (What I would call a "queue & node based" system, but that's not an official term). Ultimately VMWare's Distributed Resource Scheduler addresses this as you simply run a consistent number of clients per VM that you know will never conflict scheduleing-wise, then leave it up to VMWare to move the VMs around to balance out hardware usage. I'm definitely not against using VMWare to do this, but since we're a 100% Microsoft app stack, it seems like -someone- out there would have solved this problem at the application layer instead of the hypervisor layer by checking on resource utilization at the OS, SQL, SSAS levels. I'm open to ANY discussion on this, and remember no suggestion is too crazy or radical! :-) Right now, VMWare is the only option we've found to get away from "manually" balancing our resources, so any suggestions that leave us on a pure Microsoft stack would be great. Thanks guys, Jeff

  • Exchange 2003 mail non-delivery (NDR), spam activity? events 7002 & 7004

    - by HighTechGeek
    Windows Server 2003 Small Business Server SP2 Exchange Version 6.5 (Build 7638.2: Service Pack 2) This network has been neglected and has been having email problems for years and was on many blacklists. I was called in after the server eventually crashed... I got the server back up and running, but email problems persist. Outgoing mail delivery is sporadic. Sometimes the mail goes through, sometimes a delayed delivery report is generated after a day or more, and sometimes it seems to go through, but the recipient never receives it. Not sure if spammers are successfully using the server as a relay (see event entries below after turning on maximum SMTP logging)... User PCs infected with viruses and server was blacklisted on many sites (I used mxtoolbox.com) I have cleaned all the PCs and changed all passwords (including administrator) I have requested removal from all of the blacklists - most have removed the listing, some take more time. I have setup rDNS pointer records with the ISP (Comcast) - that was one reason for some of the blacklistings. I have tested that it's not an open relay using telnet as described here: www.amset.info/exchange/smtp-openrelay.asp I followed the advise of a Spamhaus & Microsoft article to enable maximum SMTP logging. http://www.spamhaus.org/faq/answers.lasso?section=isp%20spam%20issues#320 which directed me to Microsoft KB article 895853, specifically, the part 2/3 down titled: "If mail relay occurs from an account on an Exchange computer that is not configured as an open relay" .

  • Brother bPAC SDK - Examples only print after Form is shown

    - by Scoregraphic
    Hi there We have a small Brother Barcode printer which we like to control from a WCF Service. Brother has an API called bPAC SDK version 3 which allows to print those labels. But the problem arises, as soon as we want to print from code only without showing a windows with a button on it. As an addition, this happens only if you want to print a QR-code as barcode. Standard EAN-codes seems to work. Below is a small piece of code which outputs the stuff to a bitmap instead of the printer (debugging reasons). DocumentClass doc = new DocumentClass(); if (doc.Open(templatePath)) { doc.GetObject("barcode1").Text = txtCompany.Text; doc.GetObject("barcode2").Text = txtName.Text; doc.Export(ExportType.bexBmp, testImagePath, 300); doc.Close(); } If this is called by a button click, it perfectly works. If this is called in Form.Show-event, it perfectly works. If this is called in Form.Load-event, it does NOT work. If this is called in a Form constructor, it does NOT work. If this is called somewhere else (without forms), it does NOT work. DocumentClass and related classes are COM-objects, so I guess the form setup/show process seems to do something which is not done without opening forms. I tried calling CoInitialize with a p/invoke, but it hadn't changed anything. Is there anyone out there willing and able to help me? Are there any alternatives which (also) MUST be able to print directly on our Brother printer? Thanks lot.

    - by Madhavi
    Hi I have a page called SearchDcouments.aspx that displays all the matching documents as Hyperlinks in the table format as below. When the User clicks on any particular document, the sample url will be: http://localhost:52483/Home/ShowDocument?docID=280 So that the DocumentID is passed as Querystring to the ControllerMethod ShowDocument and the ID is visible in the URL. Now for Security purposes, I want to hide this way of passing the Querystring parameters. Wondering what are the alternatives to hide the DocID from the URL? Appreciate your responses. Thanks Code in the View: <tbody> <% foreach (var item in Model){ %> <tr> <% string actionTitle = item.DocumentType.ToLower() == "letter" ? "Request References" : "Request Slides"; %> <td> <%= Html.ActionLink(actionTitle, MVC.Home.ShowDocument(item.DocumentID))%> </td> </tr> <% } %> </tbody> Code in the Controller: [Authorize] [HttpGet] public virtual ActionResult ShowDocument(int docID) { Document document = miEntity.GetDocumentByID(docID); switch (document.DocType.ToLower()) { case "slide": SlideRequestViewModel slide = new SlideRequestViewModel(docID); return View(MVC.Home.Views.ShowSlideRequest, slide); case "letter": RefRequestViewModel rrq = new RefRequestViewModel(docID); return DoShowRefRequest(rrq); default: break; } // Here - let's get back home return RedirectToAction(MVC.Home.Default()); }

  • NHibernate, Databinding to DataGridView, Lazy Loading, and Session managment - need advice

    - by Tom Bushell
    My main application form (WinForms) has a DataGridView, that uses DataBinding and Fluent NHibernate to display data from a SQLite database. This form is open for the entire time the application is running. For performance reasons, I set the convention DefaultLazy.Always() for all DB access. So far, the only way I've found to make this work is to keep a Session (let's call it MainSession) open all the time for the main form, so NHibernate can lazy load new data as the user navigates with the grid. Another part of the application can run in the background, and Save to the DB. Currently, (after considerable struggle), my approach is to call MainSession.Disconnect(), create a disposable Session for each Save, and MainSession.Reconnect() after finishing the Save. Otherwise SQLite will throw "The database file is locked" exceptions. This seems to be working well so far, but past experience has made me nervous about keeping a session open for a long time (I ran into performance problems when I tried to use a single session for both Saves and Loads - the cache filled up, and bogged down everything - see http://stackoverflow.com/questions/2526675/commit-is-very-slow-in-my-nhibernate-sqlite-project). So, my question - is this a good approach, or am I looking at problems down the road? If it's a bad approach, what are the alternatives? I've considered opening and closing my main session whenever the user navigates with the grid, but it's not obvious to me how I would do that - hook every event from the grid that could possibly cause a lazy load? I have the nagging feeling that trying to manage my own sessions this way is fundamentally the wrong approach, but it's not obvious what the right one is.

  • Binary serialization/de-serialization in C++ and C#

    - by 6pack kid
    Hello. I am working on a distributed application which has two components. One is written in standard C++ (not managed C++) and the other one is written in C#. Both are communicating via a message bus. I have a situation in which I need to pass objects from C++ to C# application and for this I need to serialize those objects in C++ and de-serialize them in C# (something like marshaling/un-marshaling in .NET). I need to perform this serialization in binary and not in XML (due to performance reasons). I have used Boost.Serialization to do this when both ends were implemented in C++ but now that I have a .NET application on one end, Boost.Serialization is not a viable solution. I am looking for a solution that allows me to perform (de)serialization across C++ and .NET boundary i.e., cross platform binary serialization. I know I can implement the (de)serialization code in a C++ dll and use P/Invoke in the .NET application, but I want to keep that as a last resort. Also, I want to know if I use some standard like gzip, will that be efficient? Are there any other alternatives to gzip? What are the pros/cons of them? Thanks

  • What's a good way to teach my son to program Java

    - by Software Monkey
    OK, so I've read through various posts about teaching beginner's to program, and there were some helpful things I will look at more closely. But what I want to know is whether there are any effective tools out there to teach a kid Java specifically? I want to teach him Java specifically because (a) with my strong background in C I feel that's too complex, (b) Java is the other language I know extremely well and therefore I can assist meaningfully without needing to teach myself a new but (to me) useless language, and (c) I feel that managed languages are the future, and lastly (d) Java is one of the simplest of all the languages I know well (aside from basic). I learned in basic, and I am open to teaching that first, but I am unaware of a decent free basic shell for Windows (though I haven't really searched, yet since it's not my first choice), and would anyway want to progress quickly to Java. My son is 8, so that's a couple of years earlier than I started - but he has expressed an interest in learning to program (possibly because I work from home a lot and he sees me programming all the time). If no-one can suggest a tool designed for this purpose, I will probably start him off with text/console based apps to teach the basics, and then progress to GUI building. Oh, one last thing, I am not a fan of IDE's (old school text editor type), so I would not be put off at all by a system that has him typing real code, and would likely prefer that to a toy drag/drop system. EDIT: Just to clarify; I really am specifically after ways to teach him Java; there are already a good many posts with good answers for other language alternatives - but that's not what I am looking for here. EDIT: What about Java frameworks for 2D video games - can anyone recommend any of them from personal experience? I like the idea of him starting with the mechanics in place (main game loop, scoring, etc) and adding the specifics for a game of his own imagining - that's what I did, though for me it was basic on a Commodore VIC-20 and a Sinclair ZX-81.

  • How to utilize WebDev.WebServer.exe (VS Web Server) in x64?

    - by Nick Craver
    Visual Studio is x86 until at least the 2010 release comes around, my question is can anyone think of a way or know of an independent ASP.NET debug server that's x64 for 2008? Background: Our ASP.NET application runs against Oracle as the DB. Since we're on 64-bit servers for memory concerns later, we need to use Oracle's 64-bit drivers (Instant Client). Setup: x64 OS (XP or Windows 7) IIS (5 or 7, both x64 App Pools) Oracle 64-bit Instant Client (Separate Directory, in the PATH) Visual Studio 2008 SP1 In IIS the application pool runs as 64-bit, uses the Oracle drivers as intended, however since WebDev.WebServer.exe is 32-bit you'll get a BadImageFormatException because it's trying to load 64-bit driver DLLs in a 32-bit environment. All of our developers would like to be able to use the quick debug server via Visual Studio 2008, but since it runs as 32-bit we're unable to. Some problems we run into are during application startup, so although we're attaching to the IIS process sometimes that isn't enough to track an issue down. Are there any alternatives, or work-arounds? We would like to match our Dev/Val/Prod tiers as much as possible, so everything running in x64 would be ideal.

  • cookieless sessions with ajax

    - by thezver
    ok, i know you get sick from this subject. me too :( I've been developing a quite "big application" with PHP & kohana framework past 2 years, somewhat-successfully using my framework's authentication mechanism. but within this time, and as the app grown, many concerning state-preservation issues arisen. main problems are that cookie-driven sessions: can't be used for web-service access ( at least it's really not nice to do so.. ) in many cases problematic with mobile access don't allow multiple simultaneous apps on same browser ( can be resolved by hard trickery, but still.. ) requires many configurations and mess to work 100% right, and that's without the --browser issues ( disabled cookies, old browsers bugs & vulnerabilities etc ) many other session flaws stated in this old thread : http://lists.nyphp.org/pipermail/talk/2006-December/020358.html After a really long research, and without any good library/on-hand-solution to feet my needs, i came up with a custom solution to majority of those problems . Basically, i'ts about emulating sessions with ajax calls, with additional security/performance measures: state preserved by interchanging SID(+hash) with client on ajax calls. state data saved in memcache(or equivalent), indexed by SID security achieved by: appending unpredictible hash to SID egenerating hash on each request & validating it validating fingerprint of client on each request ( referrer,os,browser etc) (*)condition: ajax calls are not simultaneous, to prevent race-condition with session token. (hopefully Ext-Direct solves that for me) From the first glance that supposed to be not-less-secure than equivalent cookie-driven implementation, and at the same time it's simple, maintainable, and resolves all the cookies flaws.. But i'm really concerned because i often hear the rule "don't try to implement custom security solutions". I will really appreciate any serious feedback about my method, and any alternatives. also, any tip about how to preserve state on page-refresh without cookies would be great :) but thats small technical prob. Sorry if i overlooked some similar post.. there are billions of them about sessions . Big thanks in advance ( and for reading until here ! ).
