• MS NPS denying access, can't validate server certificate

  - by Fred Weston

  At my office we use a Cisco WLC2504 wireless controller and starting about a week ago we started having problems with users connecting to one of our secure wireless network. We are running AD on Windows Server 2008 R2 and use network policy server to control access to our wireless network. When I look at the logs in event viewer after a failed connection attempt I see an access reject message: Reason Code: 262 Reason: The supplied message is incomplete. The signature was not verified. Looking this up on Google I found this article: http://support.microsoft.com/kb/838502 I tried disabling server certificate validation on my computer and as soon as I did that I was able to connect to the network, so it seems that there is some sort of certificate validation issue. I'm not sure which certificate is unable to be validated or how to fix it. This used to work and stopped suddenly by itself so I am thinking a certificate may have expired. When I go to NPS Policies Network Policies My policy Constraints Auth methods Microsoft PEAP and view the properties, the certificae specified here expires in 2016, so doesn't seem as though this could be the problem. Any suggestions on how to troubleshoot this issue?

• Intermittent Windows Server 2008 BSOD and restart

  - by Timka

  Our EC2 Instance (Windows Server 2008) crashed multiple times for the past 3 months (last time was today at 1:05 EST). Upon reviewing MEMORY.DMP file we noticed that possible cause of the crashes is rhelnet.sys (RedHat PV NIC Driver). Server's Event Viewer has the following records right after the crash: Critical - Kernel Power: The system has rebooted without cleanly shutting down first. This error could be caused if the system stopped responding, crashed, or lost power unexpectedly. BugCheck: The computer has rebooted from a bugcheck. The bugcheck was: 0x000000d1 (0x000000000000002d, 0x0000000000000002, 0x0000000000000000, 0xfffff88001402d14). A dump was saved in: C:\Windows\MEMORY.DMP. Report Id: 100113-35849-01. Could this be a hardware issue? Would it help if we stop and start the instance? Or is this more likely that this is caused by the software running on the system? [Update 10.01.2013] Amazon Rep suggested to update RH drivers to Citrix PV drivers on our instance: Upgrading PV Drivers [Update 10.08.2013] We performed a drivers upgrade on the cloned instance. Right after the upgrade we noticed the following errors in our Event viewer: Xennet6 errors in Event Viewer (Event ID# 5001) After digging a bit more I found this article suggesting to install the latest Citrix drivers. Unfortunately, this didn't help us at all and our cloned instance became unresponsive. [Update 10.08.2013 2] I recreated an instance and updated PV drivers again. After searching on Internet I found this article where Amazon Rep explains that: "Event ID 5001 from source Xennet6 cannot be found" message does not indicate anything wrong, just that the PV driver is looking for a feature that we have not implemented in our version of Xen. I will keep my test system running for a while to see if there any issues with it.

• Upgraded AGPM Server cannot connect to relocated archive

  - by thommck

  We were using the Advanced Group Policy Management (AGPM) v3.0 on out Windows Server 2008 DC. It kept the archive on the C: drive. When we upgraded to AGPM v4 we relocated the archive to the D: drive. Now when we try to look at a GPO's hisory in GPMC we get the following error Failed to connect to the AGPM Server. The following error occurred: The server was unable to process the request due to an internal error. For more information about the error, either turn on IncludeExceptionDetailInFaults (either from ServiceBehaviorAttribute or from the configuration behavior) on the server in order to send the exception information back to the client, or turn on tracing as per the Microsoft .NET Framework 3.0 SDK documentation and inspect the server trace logs. System.ServiceModel.FaultException (80131501) You are able to click Retry or Cancel. Retry brings up the same error and Cancel takes you back to GPMC and the History tab displays "Archive not found". I installed the client on a Windows 7 computer (which is a n unsupported set up) and it could read the server archive without any issues. I followed the TechNet article "Move the AGPM Server and the Archive" but that didn't make a difference How can I tell the server where the archive is?

• multiple monitor, ATI EyeFinity vs NVidia Mosaic on HDMI

  - by user1531897

  i have been googling much for answer but only someone with real experience can help here. my aim is to have 5 monitors connected to one computer in 2x2 full screen on all 4 monitors (video wall) with same resolution, 4xfullHD for example, plus one -5th monitor as controling. Ati have example picture of this configuration here. I have no gaming nor 3d needs here. Simple desktop applications plus video streams. So because graphic cards for this are expensive, i need to find out before buying pros and cons of 2 possible solutions (1) Ati Eyefinity capable card(s) ...and (2) Nvidia Quadro/NVS card(s) with mosaic and/or nvidia surround technology. For example i can find that current good cards for this can be: Ati's 7870 eyefinity6 card, link here pros: one card can handle all 5 displays, cons: active DP adapters needed (sometimes with aditional usb-powering complication) Nvidia Qudro NVS 450, link here Both cards have DisplayPorts as outputs (my targets are HDMI displays), but as far i saw information is that Eyefinity needs "active DP-DVI/hdmi adapters" for outputs and they are little expensive...? Does nvidia have this limitation (active adapters) ??? And final question, is Ati Eyefinity still better for this purpose than Nvidia-mosaic by someone's real experience there.

• Lotus NotesSQL Driver - cannot install

  - by PowerUser

  Hi all, I need to install Lotus NotesSQL Driver (current version is 8.5) onto a virtual machine running XP. Here's what's I've done so far: I retrieved the file (CZOWFEN.zip) from the IBM website. I ran the exe. I then went to My Computer-Properties-Advanced-Environmental Settings-System Variables-Path and added "; c:\notessql" so the ODBC administrator could find Notes.ini (why the setup file didn't do this in the first place, i don't know). I opened up the ODBC administrator and tried to add a new System DSN to a Lotus DB. "The setup routines for the Lotus Notes SQL Driver (*.nsf) ODBC driver could not be loaded due to system error code 126" I redownloaded and reinstalled the driver (making sure I had the latest version 8.5). No luck. I checked the registry. All the file paths appeared to be correct. Per many, many similar cases on the internet, I tried several different variations of adding the various Lotus Notes folders to my PATH variables. Same error. I've done this setup on 5 different machines now with no problem. The only difference here is that this machine is virtual. Ideas?

• SQL Server 2008 Cluster Installation - First network name always fails

  - by boflynn

  I'm testing failover clustering in Windows Server 2008 to host a SQL Server 2008 installation using this installation guide. My base cluster is installed and working properly, as well as clustering the DTC service. However, when it comes time to install SQL Server, my first attempt at installation always fails with the same message and seems to "taint" the network name. For example, with my previous cluster attempt, I was installing SQL Server as VSQL. After approximately 15 attempts of installation and trying to resolve the errors, e.g. changing domain accounts for SQL, setting SPNs, etc., I typoed the network name as VQSL and the installation worked. Similarly on my current cluster, I tried installing with the SQL service named PROD-C1-DB and got the same errors as last time until I tried changing the name to anything else, e.g. PROD-C1-DB1, SQL, TEST, etc., at which point the install works. It will even install to VSQL now. While testing, my install routine was: Run setup.exe from patched media, selecting appropriate options After the install fails, I'd chose "Remove node from a SQL Server failover cluster" and remove the single, failed, node Attempt to diagnose problem, inspect event logs, etc. Delete the computer account that was created for the SQL Service from Active Directory Delete the MSSQL10.MSSQLSERVER folder from the shared data drive The error message I receive from the SQL Server installer is: The following error has occurred: The cluster resource 'SQL Server' could not be brought online. Error: The group or resource is not in the correct state to perform the requested operation. (Exception from HRESULT: 0x8007139F) Along with hundreds of the following errors in the Application event log: [sqsrvres] checkODBCConnectError: sqlstate = 28000; native error = 4818; message = [Microsoft][SQL Server Native Client 10.0][SQL Server]Login failed for user 'NT AUTHORITY\ANONYMOUS LOGON'.

• UNC Path fails by IP "no network provider accepted the given network path", but works using hostname

  - by BoyMars

  I have an unusual problem with a Windows Server 2003 (Standard x86) box. It appears the machine will not accept connections to its shares (locally and from other domain member servers) by using its ip address in a UNC path. The error returned is: "no network provider accepted the given network path" This is the case with the machine's ip address: \\10.0.8.x and even the loopback address: \\127.0.0.1 \\localhost does not work... but using the hostname (fqdn or not) works: \\server & \\server.domain.local The local windows firewall for this server is off, ping/rdp/other services respond fine using the IP address. The following services are running and have been restarted: Computer Browser Workstation Server The server itself has been rebooted too. Event 8032 in the system log indicates that: The browser service has failed to retrieve the backup list too many times on transport \Device\NetBT_Tcpip_{29A6A925-AFB3-47E2-BA59-DDA086DEAE7A}. The backup browser is stopping. The domain controller has not been restarted, no other servers have experienced this problem, yet there are a number of browser (8021) related errors in the logs on this server. Does anyone have any suggestions? I would like to avoid rejoining this server to the domain if possible.

• Windows Server 2003 Trial Activation Issue

  - by Adam Batkin

  I have a Windows Server 2003 (R2 Enterprise with SP2) VM, originally installed with a trial license. We forgot about the server, and now more than 120 days has passed, and I can't do anything with the server. I seem to be at a dead end with the existing installation. When I log in, I get: The evaluation period for this copy of Windows has ended. Windows cannot start. To continue using Windows, please purchase and install a retail copy of the product. Fine. I'll do that with my MSDN media. I should add that safe mode works, but there isn't anything obvious that I found to help me there Next up, I tried repairing my installation: Boot from Server 2003 R2 Enterprise with SP2 media, tell it I want to install (as opposed to recovery console), then let it repair the existing install. Once that completes and reboots I log in: This copy of Windows must be activated with Microsoft before you can continue. You cannot log on until you activate Windows. Do you want to activate Windows now? To shut down the computer, click Cancel. Great! I click "Yes" and am left with a big blue screen. Not a blue screen of death, just a blue screen (i.e. the default windows desktop background color). No Ctrl+Alt+Del. All I can do is power cycle. I have some complex third-party software on there that I can't reinstall, which is why I haven't already built a fresh Windows VM and copied everything over. I have a backup of the VM from after trial period expired but before I installed anything. Ideas?

• Firefox Using Prism Website Icon instead of Firefox Icon in Taskbar

  - by Yaakov Ellis

  A while back, I created a website shortcut using the now discontinued Prism extension for Firefox. This worked fine at the time. However, now that Prism has been discontinued, whenever I open Firefox, when the shortcut for FF shows up my Windows taskbar, it does so with the website favico for the old Prism shortcut site that I created. If I right-click on the taskbar shortcut, it shows the old shortcut to the Prism app (even though I deleted its entry manually from C:\Users\USERNAME\AppData\Roaming\WebApps). If I then click on [Pin to Taskbar] and then right click and [Unpin from Taskbar], the icon will switch back to the FF icon. If I righ-click on it a third time, it will switch back to the Prism site favico. I assume that if I were able to install Prism, then it would give me some way to remove the site. However, since Prism is discontinued and incompatible with the current version of FF, that is not an option. What I would like to do: completely remove references to the Prism app from my computer: Disassociate the prism website Favico from Firefox, so that it never replaces the FF icon in the Windows taskbar Shortcut to the Prism site will never shot up in the right-click menu for FF

• Windows 8 DLNA streaming of MKV files

  - by dbb

  I have a Samsung TV that is capable of playing MKV files. The Windows DLNA Play To menu that appears when you right-click a media file does not support MKV files, but a simple trick has been to change the file extension from .mkv to .avi so the Play To context menu item would appear. At that point I could successfully stream from my computer to my TV. However, this does not appear to work in Windows 8. Doing the same thing in Windows 8 causes the Play To window to open but the file does not get played. Dragging and dropping the file in the Play To window causes it to be silently ignored. Using actual AVI, MP4, etc. files works, of course. It appears Windows 8 is now doing some kind of validation on the file that Windows 7 wasn't previously. The Play To window does not show any kind of obvious error message or warning and there is nothing in the Windows event log. So, is there a way in Windows 8 to stream MKV files to a DLNA device without converting it to another container format? I would rather not use extra third-party software, but I would consider it if it's purposefully designed for this simple case rather than a more robust "media library/server" solution.

• Terminal Server 2008: Installing 16-bit Application (FoxPro 2.6)

  - by JohnyD

  I have one physical Windows 2008 R2 server running Hyper-V. Running under Hyper-V I have a virtual Windows Server 2008 R2 server running Remote Desktop Services (Terminal Services). I'm preparing my applications using the "Install Application on Remote Desktop..." control panel app. So far so good. However, I am now trying to install FoxPro 2.6 which is a 16-bit windows application. When I try to install it I receive the message: "The version of this file is not compatible with the version of Windows you're running. Check your computer's system information to see whether you need an x86 (32-bit) or x64 (64-bit) version of the program, and then contact the software publisher". Is there any way around this? I'm in the middle of a large migration to thin-clients and foxpro 2.6, while it won't be around forever, is a very integral application for our data-entry personnel. How can I get this to work? Thanks in advance!

• Intel 1.83 Mac Mini upgraded to 1.5 gig for Snow Leopard

  - by Paula

  Even though I've upgraded countless video cards, RAM, harddrives, motherboards in PCs... this will be my first mac mini RAM upgrade. I've watched the classic "putty knife" video. (Absurd method... but I guess it's what I'm stuck with.) I have a 1.83 Intel-based Mac Mini from 2007-2008, with 1 gig of RAM. (Two 512 sticks) Can I install 1 gig + 512 ? (Or do I have to throw away my existing sticks and buy two 1 gig sticks?) This old machine is rarely used... so I want to spend the absolute minimum on this RAM upgrade. We ONLY use it to run xCode... nothing more. But wanted to increase the RAM so we can install Snow Leopard. I have no idea how many pins the memory has. I printed out over FORTY pages of specs about this machine from "About this Mac"... but didn't find what I needed. Does this sound right: DDR2 SDRAM (but no mention of SO-DIMM) 667MHZ (but don't know if I can use faster also) Pin count: Unknown Computer model number: Unknown (But I "think" it's an MB138/A) PC2 RAM (unknown... not mentioned) 5300 (unknown... not mentioned) Mfg date: (unknown... not mentioned) Number of slots: (unknown... not mentioned) Laptop or desktop RAM: (unknown... not mentioned)

• Windows7 - “The specified network password is not correct.” when the password is in fact correct.

  - by Win7 Home User

  I have a samba server setup for some time now. It is a Hardware NAS - which unfortunately does not provide access to the Samba logs. (the exact model of the NAS is called Addonics NAS Adapter ) I also have a Windows Vista and a Windows XP machine - from both I am able to map \\192.168.0.20\Smd with no errors ( net use l: \\192.168.0.20\Smd works, after asking for my username and password). I also bought a brand new computer, with Windows 7, and when I try to execute the same exact net use command on it - using the exact same username/password pair, I get a "The specified network password is not correct." message. I also tried mapping from the Windows explorer menu, and got the same error. I synchronized the clocks of the two machines, tried again... and yet the same error persists. So what is really surprising here is that mapping works from WindowXP and Windows Vista machines, but fails from a Windows7 machine using the exact same command and username/password - Anyone has any idea of what could be causing this or how to solve the problem? Thanks

• Firebird 2.1: gfix -online returns "database shutdown"

  - by darvids0n

  Hey all. Googling this one hasn't made a bit of difference, unfortunately, as most results specify the syntax for onlining a database after using gfix -shut -force 30 (or any other number of seconds) as gfix -online dbname, and I have run gfix -online dbname with and without login credentials for the DB in question. The message that I get is: database dbname shutdown Which is fine, except that I want to bring it online now. It's out of the question to close fbserver.exe (running on a Windows box, afaik it's Classic Server 2.1.1 but it may be Super) since we have other databases running off of that which need almost 24/7 uptime. The message from doing another gfix -shut -force or -attach or -tran is invalid shutdown mode for dbname which appears to match with the documentation of what happens if the database is already fully shut down. Ideas and input greatly appreciated, especially since at the moment time is a factor for me. Thanks! EDIT: The whole reason I shut down the DB is to clear out "active" transactions which were linked to a specific IP address, and that computer is my dev terminal (actually a virtual machine where I develop frontends for the database software) but I had no processes connecting to the database at the time. They looked like orphaned transactions to me, and they weren't in limbo afaik. Running a manual sweep didn't clear them out, deleting the rows from MON$STATEMENTS didn't work even though Firebird 2.1 supposedly supports cancelling queries that way. My last resort was to "restart" the database, hence the above issue.

• Howto make a diff of a bios or backup/ restore all bios settings

  - by sfonck

  Hi, I'm using an Dell M90 Precision Laptop which has a NVidia Quadro FX 2500M graphics card and is running Windows XP. Laptop has been running fine - but a few weeks ago screen went 'white' - restarted computer- bios and startup screens show weird green dots and stripes, normal startup only shows a black screen... only VGA mode works to display something. I've been trying to remove and reinstall the correct drivers downloaded from Dell's website - no solution. I gave up and reinstalled XP - everything was working perfect again. 2 weeks later - again the white screen - tried everything again (flashin new bios also - nothing works) Reinstalled XP - everyhting was working again, so I made a DriveSnapShot of the partition. Today - again the 'white screen'. Ok, no problem ...I was thinking all I needed to do was to restore the DriveSnapShot backup... Few minutes later the backup is restored ... but guess what: video driver does not work correctly... As the DriveSnapShot restored the complete partition, as it was at the time everything was working perfectly, this would mean my driver problems are due to 'settings' in the bios or on the graphics-card itself + these 'settings' can get overridden by doing a new XP-install.... I'm out of options, can somebody help me to find a solution for this problem: Is there some way to backup and restore a bios after seeing some problems? Is there some way to know what is causing this problem like a bios diff utility? Thanks!

• Ubuntu12.04 crashed while trying to install Ubuntu14.04, no longer have access

  - by FACE

  Posting from my laptop, as my Compaq desktop crashed. Not very computer saavy, and not sure what info I should provide...but here's a start: 9 year old desktop Compaq SR 1650NX, AMD Athlon 3500+ probably 1 gB ram (duh....) Was running 12.04....was attempting to upgrade to 14.04, not sure if I interrupted it. Pretty much stuck on (constantly redirected to) a page which says "GNU Grub version 1.99-2"; it offers several choices (as written): Ubuntu, with Linux 3.2.0-67-generic Ubuntu, with Linux 3.2.0-67-generic (recovery mode) Previous Linux versions Memory Test (memtest86+) Memory Test (memtest86+, serial console 115200) But none of the selections seem to be able to get me anywhere (i.e., I click yes, but can't seem to run any commands - not that I know anything useful); I escape from those pages by repeatedly hitting CTRL-ALT-DEL Any help would be appreciated; will provide additional info when requested. Thanx (hopefully), in advance. (If I don't respond immediately, it just means I had to attend to other concerns...will leave page open and check back in as often as possible). FACE

• Ideal Bacula appliance?

  - by Ricket

  I'm an intern at a small company and we (the IT department of two) manage <100 client computers and a handful of servers. Currently we're using a company's appliance to handle backup; it does a small backup every night and a full backup every weekend, and a guy comes on Wednesday to take an offsite backup drive (and gives back last week's drive to swap with it). Lately this system, mainly the appliance, has been having problems, so we are looking for an alternative. I'm researching other companies but also looking into what we might expect from trying to do this ourselves. There will undoubtedly be a large learning curve, but hey, that's what serverfault is for, right? :) So anyway I was looking at Bacula. Feature list sounds great, documentation is plentiful, but it's only software. So my question is, what is the ideal backup server to run the Bacula server software on? And not only the server but other related appliances. Our current backup appliance uses only hard drives, not tape drives. It has several plugged into it at one time, in hotswap bays on the front of the machine. I couldn't help but notice though, it's hardly more than Windows XP with hard drive bays, a PCI eSATA card (which connects to another appliance extension piece with 2 more bays), and their software. Since the company will take back their appliance if/when we cancel with them, where can I go to configure a server with these kinds of things? Maybe I'm being naive, I'm sure Dell (and any other computer company) sells them in the small business section of their website, but I wanted to make sure that there's not some other more recommended place that other companies are getting their hardware from, and that I don't need anything special for Bacula.

• psexec: "Access is Denied"?

  - by Electrons_Ahoy

  Inspired by my previous question here, I've been experimenting with PSExec. The goal is to trip off some fairly simple scripts / programs on one WindowsXP machine from another, and as PowerShell 2 doesn't yet do remoting on XP, PSexec seems like it'll solve my problems nicely. However, I can't get anything but the "Access is Denied" error. Here's what I've tried so far: I've got a pair of WindowsXP MCE machines, networked together in a workgroup without a server or domain controller. I've turned off "simple file sharing" on both machines. Under the security policy, Network Access: Sharing and Security model for local accounts is set to Classic, not Guest for both machines. There is an Administrative user for each computer that I know the passwords to. :) With all that, a command like "> psexec \\otherComputer -u adminUser cmd" prompts for the password (like it should) and then exits with: Couldn't access otherComputer: Access is denied. So, at this point I turn to the community. What step am I missing here?

• 4in6 tunneling (via OpenVPN?)

  - by Deshene

  I have a local network with internet access. But unfortunately IPv4 internet connection speed is limited to 1mbps, which is realy sad. Fortunately I have a native IPv6, and there is no connection speed limit over IPv6. So, in order to get a good internet connection I made a plan: connect to the VPN-service over IPv6, and pass all IPv4 traffic through IPv6 tunnel, or something like that, I think you get the idea. I suggested to use service like HideMyAss.com, but unfortunately they don't support IPv6. The question is: Is there any existing VPN service that will make my dreams come true, and is easy to use, which I could connect over PPTP or OpenVPN (I want to set up connection to VPN in my router settings). Edit: It seems like there are couple of VPN services that supports IPv6 (it's odd, but the biggest VPN services support only IPv4), and there is none providing 4in6 tunnels. So, I came to the following solution: rent a VPS with IPv6 address, and manually setup 4in6 tunnel. I'm not good at networking, never did things like that, and don't know where to start, and what should I do. The use case, as I undestand, should look like this: I connect from my home computer to the VPS via OpenVPN, and after that all my IPv4 traffic pass through IPv6 (server do the job). OpenVPN - because I want to configure VPN connection to server in my router (Asus RT-N16?). How can I achieve this?

• Group policy waited for the network subsystem

  - by the-wabbit

  In an AD domain with Windows Server 2008 R2 DCs users are complaining about delays in the bootup process of the clients. The group policy log reveals that the client is waiting ~ 20-50 seconds for "the network subsystem": Event 5322, GroupPolicy Group policy waited for 29687 milliseconds for the network subsystem at computer boot. This appears to be domain-specific as machines joining a different domain from the same network do not experience any delays and Event 5322 reports <1000 ms wait times at startup. It happens on virtual and physical machines alike, so it does not look like a hardware- or driver-related issue. Further investigation has shown that the client is taking its time before issuing DHCP requests. In the network traces, I can see IPv6 router solicitations and multicast DNS name registrations as soon as the network driver is loaded and the network connection is reported "up" in the event log (e1cexpress/36). Yet, the DHCPv4 client service seems to take another 15-50 seconds to start (Dhcp-Client/50036), so the IPv4 address remains unconfigured for a while. The DHCP client's messages in the event log are succeeding the service start of the "Sophos Anti-Virus" service (Sophos AV 10.3 package), which I suspect to be the culprit - the DHCP client service dependencies include the TDI Support driver which might be what Sophos is using to intercept network traffic: Network Location Awareness seems to break at startup as a side-effect, I see that off-site DCs are contacted due to what seems like a race condition between the GP client and the DHCP client / NLA service startup. I could set the Group Policy Client service to depend on NLA, yet this still would not eliminate the delay. Also, I am not all that sure that this is a good idea. Is there a known resolution which would eliminate the startup delay?

• The System Event Notification Service service terminated with the following error: Overlapped I/O operation is in progress

  - by user38923

  When I start my Windows 7, I get a notification The system event notification service could not be started.... As a result, I dont have Aero, even though my Windows Experience Index is 3.2. Aero used to work fine before today and I have not installed any new application. I have checked the event log and it reads: The System Event Notification Service service terminated with the following error: Overlapped I/O operation is in progress. I am not sure what this means. I have seen the services.msc and everything is fine there. Moreover the startup time has also extended and the Please wait stays for more than a minute. This is a sudden problem as everything used to work fine until today. For Aero I have tried starting Desktop Window manager (as pointed out by the trouble shooter), but with avail. From what I could understand from the forums, the lack of Aero and increased start-up time comes from a single problem of the System Event Notification Service. This is a personal Computer and I have no active directories installed.

• User cannot access a system DSN on Windows Server 2008

  - by Ra Osolage

  We run our SQL Server services using a low privileged domain account. That account is NOT a local admin on the OS. Only access I give the user account is assigned during install of SQL: full control over its mount points and then everything else is granted by the SQL Server 2005/2008 installer. I need to create a linked server in SQL Server 2008 to an ODBC data source. So I remoted into the computer using my domain account, which is part of a group that DOES have local admin privs to the OS. I created a system DSN and configured it to connect to another SQL Server. The DSN works perfectly when I test it. However, when I try to create the linked server, I get an error. It appears to me that the DSN is invisible to the domain account that SQL Server is running as. It seems that this problem is only happening to me on Windows 2008 servers. Does anybody know whether there's anything that you need to do after creating a DSN to make it visible for other users to access?

• Issues with doing a P2V on Exchange 2007

  - by PokermUNKEE

  I shutdown all Exchange services on the physical box and did a convert. Everything converted fine. Server booted up no issues and I could receive email from the outside world with no issues. But I am unable to send emails internally or externally. They just sit in the Outbox. I also disabled the DHCPClient service as I didn't want the server to get an IP address from DHCP when it first came online. It came online with no IP, then I used console to assign the correct static IP address (same one on the physical server) and rebooted. I ran the Exchange Troubleshooting Agent and it gave me the following errors: The value for the '\MSExchangeIS Mailbox\Messages Queued For Submission' counter on server exchange is greater than zero (average value is 8.8) and it appears that 'MSExchangeMailSubmission' is failing to submit messages to at least one computer with the Hub Transport server role installed over the last minute. Found 1 computers with the Hub Transport server role installed in the same Active Directory site as server exchange using local Active Directory site GUID 'ce8a4367-1bf6-4825-9cac-c4e2b115c450'. Check Local Active Directory Site Hub Transport Server Role Health (Mailflow_CheckLocalBhHealth1.1.1.1.1.1.1.1) I have one Exchange server with all the roles on it. Has anyone see this before when doing a convert? Please help :(
