• in HFT trading should I upgrade from Windows Server 2008 R2 to Windows Server 2012?

  - by javapowered

  I'm using HP DL360p Gen8 + Windows Server 2008 R2 for HFT trading. That means that every 10 microseconds is important for me. I do understand that if I need everything to be so fast I probably should consider using Linux. But in this post I want to compare only Windows Server 2008 R2 and Windows Server 2012. I've found in internet couple articles that suggest how to tune Windows Server 2012 for low latency http://msdn.microsoft.com/library/windows/hardware/jj248719 http://technet.microsoft.com/en-us/library/hh831415.aspx Most part of optimizations from these articles apply only to Windows Server 2012 and can not be used on Windows Server 2008 R2. So now I think that as I can optimize Windows Server 2012 for low latency, probaly I should upgrade? After optimizations how much faster windows server 2012 would be (ideally in microseconds :)?

• Disable remote session timeout on Win Server 2012 R2

  - by Sarchophagi

  For botting purposes, I have to keep my Win Server 2012 R2 running without logging-off after I disconnect from Remote Session. Found information about it here: http://technet.microsoft.com/en-us/library/cc754272.aspx but I just its for Win Server 2008 and doesn't seem to work on 2012 version. Could you guys help me setting infinite timout? EDIT: Tried this answer Changing the login timeout for Windows Remote Desktop Services but without results..

• I get Get-WmiObject : Generic Failure error on an XP Machine. What needs to be done to get rid of this?

  - by steeluser

  I am trying make an uninstall app which removes an application X on a regular basis. The starting point to access applications installed in a Windows machine is through retrieving them from a WMI Class called Win32_Product. But when I run the basic command like this, I get the below error. I have searched technet and SO, but either their workarounds did not work for me or were too technical in detail which did not make sense to me. Please help.

• moving dynamic disk from Windows to another Windows computer when original Windows is not available

  - by Andrei

  How do I mount dynamic disk on new system without access to the old OS ? I need to move Dynamic data disk from old Windows XP (Pro, SP3) system, where disk crashed, to new Windows system without having access to the old OS. On new system, Dynamic disk shows as "Dynamic - Foreign". Microfoft has instructions for moving Dynamic Disk [1]. But Microsoft assumes having access to the old system. But I do not have acess to the old system. I am struck with "Dynamic - Foreign" static of the disk on new system. Thanks WinXP Pro SP3 [1] http://technet.microsoft.com/en-us/library/cc779854(WS.10).aspx Move Disk to another computer.

• Any Way to monitor JMX Servers with NetIq ?

  - by Carlos

  I ask this question after a search in the site, there's many JMX questions but I think no one with a NetIq involved. In the documentation of NetIq, There's no "module" to check JMX, but I have seen that u can make "custom" modules and "custom" scripts, in Perl and VbScript. The question is if anyone with more experience than me on NetIq, has made any custom script or module to check JMX. I look on technet too, for a JMX Api for Windos Shell or Powershell with no luck. Of course, JMX is much more powerfull, but what I really need is to "monitor" some values inside NetIq, because we cant install Nagios, Cacti, Hyperic or any other monitor software but NetIq. Thanks.

• How to sort by file's modified date on IIS web server in Windows 7?

  - by ????

  Apache has this built in since 1996 which is 17 years ago... for Microsoft's IIS Web server which is available on Windows 7, is there a way to make it be able to sort the file listing by file modification dates? For example, show the file listing with the label "Date", "Filename", and clicking it will sort the files by that attribute. The only info I could find is: http://technet.microsoft.com/en-us/library/cc732762(v=ws.10).aspx cd %windir%\system32\inetsrv appcmd set config /section:directoryBrowse /showFlags:Time|Size|Extension|Date|LongDate|None but it doesn't work.

• how to use iis 6.0 redirects?

  - by payling

  I'm attempting to use the below reference to create a re-direct for my local site with no luck. http://www.microsoft.com/technet/prodtechnol/WindowsServer2003/Library/IIS/6b855a7a-0884-4508-ba95-079f38c77017.mspx?mfr=true I want absolute links on my local site that point online to point to my local site instead. example absolute link [http://online.com/products] when I click the local version I'd like it to redirect to: [http://offline/products] I want to preserve everything after the domain name and append it to the server (local) name so that when I click a link it will redirect to the local site and not the online version. I've tried [http://offline$S] but that doesn't append the "suffix" /products the way I thought it should. What's going on here?

• Performance issue when configuring non HA VM in cluster

  - by laiys

  Hi, I saw this article http://technet.microsoft.com/en-us/library/cc764243.aspx Quote taken from the link “ Important It is recommended that you not deploy virtual machines that are not highly available on your host clusters. Although you can do this by using Hyper-V (VMM does not allow it), the non-highly available virtual machines will consume resources that otherwise would be available to the HAVMs What kind of resources (CPU,memory, NIC, etc) that non HA VM will consume? Just curious as not all VM (in production) not to be in Failover Cluster and Live Migration. If i put the VM into CSV but did not make it as HA, what impact does it make since i allocate same vCPU, vNic and VMemory into the VM. (not to mention that i lost failover feature). Curious to understand more about this. Please advise. Thanks

• HP Compaq T20 Thin Clients & Windows Server 2008 R2: RDP Disconnects instantly.

  - by sinni800

  Hello, I have some HP Compaq T20 Thin Clients connecting to a Windows Server 2003. Now I want to upgrade to 2008 R2, so I tested a trial installation with remote desktop in administration mode. So I try to connect my T20 to the server and... It doesn't matter if I turn off encryption or not it disconnects with an generic error instantly. The T20s have Windows CE embedded with RDP 5.2 installed. Out of curiosity I tried Windows Server 2008 (no R2) and it worked! I tried the same with a Windows 7 machine set up with- no work. I can not update the T20s to Windows NT embedded for example because they only have a low amount of flash memory. It seems the "new" version of RDP coming from Windows 7 / Windows Server 2008 R2 is completely incompatible with the older 5.2 version. People are having the same problem here: http://social.technet.microsoft.com/Forums/en-US/winserverTS/thread/700488cd-a872-47e5-85a7-595f050afc10

• can't add sharepoint users from trusted domain

  - by user22215

  I have a very strange problem with our Sharepoint 2007 implementation. I went in today to grant access to a user and was greeted with "The user does not exist or is not unique." Let me start off by saying that this user is not on our domain we have a 2 way trust connecting to one of our subsidiaries. I can see the users in the people pick but can't add them into Sharepoint. This problem flared up after we had some trust issues last two days ago. So I must ask has anyone came across this error and if so what steps did you take to resolve it? This link further highlights my problem: http://social.technet.microsoft.com/forums/en-US/sharepointgeneral/thread/41265a91-191c-4952-9c8c-1e0129b9fd3a

• Exchange 2010 SP2 Not Allowing Logon for Users with Expired Passwords

  - by JJ.

  When we provision users we set the "User must change password at next logon" flag and instruct them to go to OWA to login for the first time and change their password. Using the registry setting ChangeExpiredPasswordEnabled as explained here: http://technet.microsoft.com/en-us/library/bb684904.aspx worked well prior to SP2 installation. This allows users with 'expired' passwords to logon and forces a password change before they can access OWA. We just installed Exchange 2010 Service Pack 2 and now it's no longer working. Users with this flag set ('expired' passwords) can't login in at all unless we clear the flag. FYI here's the registry key configuration as set now with SP2 installed: Any suggestions as to how I might fix this? Or did MS break this feature in Service Pack 2?

• Restore more than 250 files using DPM 2010 and PowerShell

  - by toryan

  I've got what should be a fairly simple task: restore the following files from DPM: D:\inetpub\wwwroot\*\index.* I followed the instructions in this TechNet wiki and pretty much thought I had it. Unfortunately, the New-SearchOption commandlet can only return 250 results, and this search would generate way more results than that. So actually only the first 250 files were restored, which is no use to anybody. Does anyone know of any way to get around the 250 search results limit? I guess it would be possible to get the subdirectories of D:\inetpub\wwwroot and loop through them in turn, but I kind of want to keep this fairly simple as it is only for this task.

• Is it possible to create a read-only user account for security auditing purposes?

  - by user2529583

  An organization requires several administrators to have a role of a security auditor. They must have read-only (via network/remote) access to Windows Server 2008 / R2 systems and have permissions to view the server configuration. They must not be able to make any other changes to the server or the network, like restarting or making any configuration chanages. However I can't find any built-in settings for a user like this. The closest thing is the "Users" user group [1], however from my understanding every user in the domain is in this group and cannot view the domain server's configuration. So, what are other options of implementing a read-only user account in Windows Server 2008? [1] http://technet.microsoft.com/en-us/library/cc771990.aspx

• In a multi-domain forest, what EXACTLY happens when some, but not all, of the Infrastructure Masters are on Global Catalogs?

  - by MDMarra

  There are plenty of TechNet articles, like this one that say that phantom object don't get updated if an Infrastructure Master is also a Global Catalog, but other than that there isn't a lot of in depth information on what actually happens in this configuration. Imagine a configuration like this: |--------------| | example.com | | | | dedicated IM | |--------------| | | | |-------------------| | child.example.com | | | | IM on a GC | |-------------------| Where child has two DCs that are both global catalogs, meaning that the Infrastructure Master role is on a GC. And, example has three DCs with the Infrastructure Master role on a DC that is not a GC. I understand that it's usually best to just make everything a GC and not have to worry about this sort of thing, but assuming that's not the case - what is the exact error behavior that can be expected from a setup like this, and which domain(s) would this behavior manifest in? The child or the parent?

• How to install Microsoft Exchange 2007 as a member server

  - by O_O

  I am trying to install Microsoft Exchange 2007 to a Windows Server 2003 as a member server. I already have a Windows Server 2008 as my domain controller. I'm having a hard time figuring out what is needed to prepare the machine for Exchange 2007 installation. My specific question is: While following the procedures here in the TechNet Library , do I still need to go through with the section "How to Prepare Active Directory and Domains" and do the following commands if I am making it a member server and NOT a domain controller? ie.. setup /ps setup /p /on: setup /PrepareDomain: Thank you.

• SCVMM upgrade scenario

  - by pigeon

  I've read some information on TechNet about upgrading SCVMM 2008 - 2012 but can't quite figure out the best way to approach this. The current setup is that we've got SCVMM 2008 R2 installed but against best practice it was actually installed on the Hyper-V host machine since its a small scale deployment its just a single server setup with SCVMM existing on the same host rather than be in a VM. So from what I've read an in-place should be possible which will incur a restart but also don't have the luxury of another server to shift the VMs onto whilst doing this or want to risk anything happening to the Hyper-V role. Ideally I would probably prefer just to get SCVMM 2012 into a VM of its own and remove the 2008 version from the host machine. Anyone done an upgrade on this or have any recommendations about how to approach this?

• Vista locks up after ~10h. of activity

  - by Naomi

  Hi everybody, I am experiencing a problem: Windows Vista completely freezes/locks up lately... It happened today twice - the mouse and keyboard stopped responding and I had to re-boot. I checked the Application Events Log and I see these two errors: Event filter with query "SELECT * FROM __InstanceModificationEvent WITHIN 60 WHERE TargetInstance ISA "Win32_Processor" AND TargetInstance.LoadPercentage 99" could not be reactivated in namespace "//./root/CIMV2" because of error 0x80041003. Events cannot be delivered through this filter until the problem is corrected. and then The following boot-start or system-start driver(s) failed to load: SASDIFSV SASKUTIL I checked Help online and it points to http://technet.microsoft.com/en-us/library/cc756390%28WS.10%29.aspx and suggests Updating the drivers. I'm not sure why would I have problem with drivers and if so, how can I find out which drivers to update? Can you please help me? Thanks in advance.

• How to Shrink large Hyper-V VM

  - by autrevo

  Using Disk2VHD utility I converted my bare-metal OS into Hyper-V VHD - http://technet.microsoft.com/en-us/sysinternals/ee656415.aspx And I could obtain a huge 190GB VHD file. Apart from performance issues, this VHD worked fine as guest when hosted on Windows Server 200 R2, Hyper-V. Having realized need to keeping only system files and application installations on VHD. I have deleted most of the junk data from this VHD and now it contains only 20-25 GB. But I am not able to shrink the VHD VM. Having done some research, I came to know, this as a limitation of .VHD files. Subsequently I followed these two step using Edit Virtual Hard Wizard on Windows 2012 Box. Convert from VHD to VHDX (took close to 3 hrs.) Compact (Another 4 hrs.) This did not ever shrink the VHDX either. Does Hyper-V does not provide proper support to handle large VHDs or VHDXs whose size are the range of 200GB.

• One-way forest trust between geographically distributed forests using Server 2008 R2

  - by bwerks

  Hi all, I'm planning out a joinder between two domains, as would take place with contracting companies. Forests A and B exist in distant sites, and there is to be a one-way forest trust so that domain users in Forest A can be authenticated on machines in Forest B. In order to facilitate this, each forest's domain controller must be able to contact each other in order to set up & confirm the trust, but my question is what underlying networking magic must take place beneath it. So far the prevailing approach has been to maintain a VPN connection between the two sites, but the technet documentation seems to indicate that DNS forwarding may be the way to go. Is this the case? Furthermore, if DNS will suffice, does that mean that there must be a server running DNS on boundary servers in each domain so that they can be reached from across the internet? How must they be configured? Thanks!

• Is it possible to re-lock a bitlocker drive?

  - by Sean Edwards

  I'm running a partition with bitlocker on a Windows 7 Ultimate machine, which contains secure data that I have to recover infrequently. Unlocking it to access the data is obviously no problem, but is there a way to re-lock the partition when I'm done? The best I've found so far is this: http://social.technet.microsoft.com/Forums/en-US/w7itprosecurity/thread/41607938-7452-440d-8253-67fe8657bc0f Currently I have a .bat script on that drive that I can run as administrator, and that re-locks the drive, but it feels like kind of a hackish solution. Does anyone have anything better? Any idea when Microsoft might release a fix for this?

• SharePoint 2010 not seeing Active Directory users

  - by user117927

  I'm pretty new to Active Directory and SharePoint but I was given to understand they are supposed to play well together. Now I have successfully set up AD with multiple user accounts that work on any member computer. I have also successfully installed SharePoint 2010 Server on an AD machine. Both the AD server and SharePoint servers are on separate machines (VMs running on ESXi to be precise). I can only log on with user accounts I create on the local server. Furthermore the user browser thing for adding users will only see local users. I've followed the advice here http://technet.microsoft.com/en-us/library/cc262350.aspx#section2 for Classic authentication and also NTLM claims based authentication but to no avail. Is there something fundamental I am getting wrong here? I'd be really thankful for any help you can lend me; I've been googling and scratching my head for a couple of days now. P

• Transport rules on a live@edu instance to filter SSNs

  - by wbfreema

  Has anyone implemented transport rules on a live@edu(or whatever Microsoft is calling it these days) instance to reject the delivery of messages that include SSN's? I see how to set up transport rules in Exchange 2007, and even how to do it in the Windows Live Admin page, though the rules there don't seem to allow for regexes, can anyone confirm this? If this is the case has anyone ever connected Powershell to a live@edu instance to implement the code found at the bottom of this page: http://technet.microsoft.com/en-us/library/aa997187.aspx What I really need is a concise how-to.

• W2k8 RC1: Windows Media Servers (WMS) as proxy

  - by da_didi

  (fullquote from stackoverflow.com/questions/2690788/w2k8-rc1-windows-media-servers-wms-as-proxy/2690791#2690791) I will have one streaming-server (W2k8, unknown streaming protocol [rtsp, mss, http]) and half dozen streaming-servers as proxies to save bandwidth. I have read the documentation and installed the modules, but I am unsure how I have to configure the proxy's according to http://technet.microsoft.com/de-de/library/ee126142(en-us,WS.10).aspx - as a proxy or reverse proxy and how I minimize the bandwidth needs between origin server and proxy's. What is the best way to realize my setup? Any short how-tos? How can I announce all players to use the proxy? Route all rtsp/mms/http-requests through my proxy? Announce the proxy with DHCP-releases?

• Exchange 2010 domainprep messing up mailbox permissions on existing Exchange 2003 server

  - by tearman

  So our environment is basically we have an Exchange 2003 server, and we're attempting to move to Exchange 2010 gradually, and move to new hardware while we're at it. So our first step was obviously to get Exchange 2010 installed on the new box. However, after running the domainprep steps listed in http://technet.microsoft.com/en-us/library/bb125224.aspx (including PrepareLegacyExchangePermissions) our mailbox permissions get messed up. Normally, we have an AD security group for Exchange Administrators that allows anyone in that group to view all folders inside any user's mailbox. However, now, this functionality is gone and our Exchange Admins can't access anyone's mailboxes. We'd like to get this functionality back if we could. Thanks
