WSUS mysteriously stopped letting me into the MMC console for it this week.
When I run the console it says:
MMC could not create the snap-in. The snap-in might not have been installed
correctly.
Name: Update Services
CLSID: FX:{8b6499ed-0241-e032-6508-da4b1c879d7e}
OS is Server Standard 2003 SP2, fully patched, with WSUS 3.0 SP1. WSUS
itself actually seems to be working. The server is a secondary domain
controller. We have SQL 2005 in mixed mode running a LOB database, but it's
been running fine for nearly a year.
Rebooting doesn't help. I uninstalled and reinstalled WSUS and it still
doesn't work. I've tried looking for MMC cache files in
%USERPROFILE%\Application Data\Microsoft\MMC and deleting them, but still no
luck. No errors are thrown into the event logs.
I'm completely stuck at this point. Does anyone know what's going on or what
I can do to troubleshoot this further?
