SYMPTOMS

After you install Windows Server 2003 Service Pack 2 or Windows Small Business Server 2003 (Windows SBS) R2 Technologies, you receive the following error message when you open a Microsoft Management Console (MMC) snap-in:
MMC has detected an error in a snap-in. It is recommended that you shut down and restart MMC.
When you receive this error message, you can select from among the following three options:
  • Report this error to Microsoft, and then shut down MMC
