Unable to open the Microsoft Management Console, MMC fails with the message:

“MMC could not create the snap-in”.

Some customers reported after install .NET update, the issue appeared, i.e http://support.microsoft.com/kb/2416473

KB 2486109(http://support.microsoft.com/kb/2486109) was published for this issue.

This problem occurs if the .Net Framework 3.0 feature is not enabled and an update for .net framework 3.5SP1 is installed (which could be through the windows update or through a deployment tool).

If the above steps can not resolve it, use this method:

 

1. Navigated to the following directory:

C:\Windows\Microsoft.NET\Framework64\v2.0.50727\CONFIG

2. Renamed machine.config to machine.config.old

3. Copy the same file from the working server.

Symptom 2:

After installing security update http://support.microsoft.com/kb/2449742, the  MMC console opens but when you try to do anything inside you may get error "Microsoft Management Console has stopped working".

The following events are logged:

Solution:

 

  • If you never installed MS11-028 or have uninstalled it, you should install KB979744-v2 from here or here and then install MS11-028
  • If you still have MS11-028 installed, and your Exchange Management tools are currently broken, you should install KB979744-v2 from here or here

  • DID NOT WORK

  • I know this is an old post, but I ran into the same issue and tried everything I could find on the internet regarding this. After working with Microsoft for 3 days we found the fix. Please see below for all the steps that were completed, and finally what solved the issue. This was for a Server 2008R2 machine:

    MMC could not create the snap-in. The snap-in might not have been installed correctly.
    Name: Server Manager
    CLSID: FX:{18ea3f92-d6aa-41d9-a205-2023400c8fbb}

    Name: Event Viewer
    clsid: fx: {b05566ad-fe9c-4363-be05-7a4cbb7cb510} Event Viewer

    Name: Task Scheduler
    clsid: fx: {c7b8fb06-bfe1-4c2e-9217-7a69a95bbac4} Task Scheduler

    Name: Windows Firewall with Advanced Security
    clsid: fx: {b05566ac-fe9c-4368-be02-7a4cbb7cbe11} Windows Firewall with Advanced Security

    Microsoft Server 2008R2 SP1
    HP ProLiant DL380G6


    Replaced C:\Windows\Microsoft.NET\Framework64\v2.0.50727\CONFIG\machine.config with known working file
    Replaced entire C:\Windows\Microsoft.NET\Framework64\v2.0.50727\CONFIG\ folder with known working folder

    Ran System Update Readiness Tool for Server 2008 – all reports came back with no error

    Ran c:\Windows\Microsoft.NET\Framework\v3.5\WFServicesReg.exe /r /b

    sfc /scannow was ran, came back clean

    Ran .NET Verifier on all version of .NET, all came back verified successfully

    Reinstalled .NET 3.5 via CLI:
    DISM /online /disable-feature /FeatureName:NetFx3
    DISM /online /enable-feature /FeatureName:NetFx3

    Removed registry keys:
    HKLM\Software\Microsft\OLE\MachineAccessRestriction and
    HKLM\Software\Microsft\OLE\MachineLaunchRestriction

    Restarted “Start DCOM Server Process Launcher” service

    Replaced files dsadmin.dll and dssite.msc located at C:\Windows\winsxs\x86_microsoft-windows-d..mc-sitesandservices_31bf3856ad364e35_6.1.7601.17514_none_a143f244c78549c1 with a good know version

    HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\MMCSnapIns\FX{b05566ad-fe9c-4363-be05-7a4cbb7cb510}\RuntimeVersion, changing value from "v2.0.40607" to "v2.0.50727"


    Final resolution from Microsoft:
    The Servicing stack of the Operating System was clean as reported by the Sfc output
    Uninstalling/Reinstlaling Visual C++ 2005/2008/2010 with a reboot took out of the picture Visual C++ library components
    The .Net Policy had the correct value under HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\.NETFramework\Policy\v2.0 - "50727"="50727-50727”
    Uninstalling McAfee didn’t help even after a reboot.
    The Components and Schema hive unloaded after a few reboots

    The IDNA trace that we gathered indicated that we fail due to a bad function pointer most probably returned by a .net component. After applying the Update https://support.microsoft.com/en-us/kb/2688730 and a reboot the issue went away which indicates we have a broken/damaged .net component on the server.
