Getting the error "MMC has detected an error in snap-in"?

 


[Today’s tip comes to us from Damian Leibaschoff]


After you install Windows 2003 Service Pack 2 or the SBS 2003 R2 Technologies, you might start seeing some MMC snap-ins displaying an error similar to this:


MMC has detected an error in a snap-in.


 


The source of the problem is that the snap-in is not fully compatible with MMC 3.0, and you most likely have already realized that both Windows 2003 Service Pack 2 and the SBS 2003 R2 Technologies install MMC 3.0.


These are some of the components that you might encounter this problem with:



  • Health Monitor MMC


    • Solution: Choose “Continue running and ignore errors with this snap-in for the rest of the session”

  • ISA 2004


  • POP3 Connector


  • Group Policy Editor Tool


    • Solution: Solved in Windows 2003 SP2. See KB915797

  • SQL Server 2000 Analysis Services


    • Solution: Choose “Continue running and ignore errors with this snap-in for the rest of the session”. See KB915091
