Thoughts from the EPS Windows Server Performance Team
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!

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
