Thoughts from the EPS Windows Server Performance Team
Useful Microsoft Blogs
Good morning AskPerf! Madhurjya here from the Windows Performance Team to alert you on an emerging issue where random MMC snap-ins will fail after installing the June 2012 .NET updates.
After installing these .NET updates on a Windows 7 or Windows Server 2008 R2/SP1 machine, certain snap-ins will fail. Most notably, the Server Manager and Event Viewer snap-ins. The following errors will be displayed when you try and open these:
If you are receiving these errors, please install one of the following hotfixes for .NET Framework:
Hotfix Rollup 2688729 is available for the .NET Framework 2.0 SP2 on Windows 7 or on Windows Server 2008 R2
Hotfix Rollup 2688730 is available for the .NET Framework 2.0 SP2 on Windows 7 SP1 or on Windows Server 2008 R2 SP1
As a note, we have not seen this issue with 32-bit snap-ins. To confirm this, you can launch 32-bit snap-ins with the following syntax:
mmc.exe /32 snap-in.msc
If the above hotfix does not resolve your issue, please open up a case with Microsoft Technical Support to further troubleshoot your issue.
Have a great weekend!
Hotfix Rollup 2733946 is available for the .NET Framework 2.0 SP2 on Windows Vista SP2 and on Windows Server 2008 SP2 support.microsoft.com/.../2733946
when we are enable remote desktop session host then we are see error mmc has detected an error in a snap in and will upload it. so how can resolve it tell me its very urgent
will this work with windows server 2008 enterprise
your command mmc.exe /32 snap-in.msc fails on my netbook..."mmc cannot open the file snap-in.msc
This may be because the file does nto exist, is not an mmc console, or was created by a later version of mmc. This may also be because you do not have sufficient access rights to the file." using windows 7 starter, service pack 1. 32 bit o/s.
Snap-in.msc is not a an actual snap-in file. You need to replace it with the name of snap-in that your trying to load. For example mmc.exe /32 gpedit.msc
