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

  • Article

 

[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
