Class not Registered

Hello all:
I'm having a problem with an error message on my Windows 2003 Small Business Server.  The title bar of the error windows is: Microsoft Management Console.  Inside the message window it says: Class not Registered.  I get this whenever I try to launch any management utiltity - Event Viewer, Server Management, Services, AD, etc. etc.  Basically, I can't do anything, and I can't find what service has become un-registered.  All this used to work.  We reinstalled the OS a little over a month ago.  Rebooting doesn't always help.  Any ideas?

Download and install MMC v3 from Microsoft's Web site: www.microsoft.com/downloads and see if that resolves it.

OK, thanks - worth a try.  I'll let you know how it goes.

Well, no dice.  I already have SP2 for Windows 2003 (SBS) installed which is the same or newer than MMC v3 - it would not install.  Any other ideas??

Anyone ??  I'm still getting this problem.  If I reboot (sometimes it takes more than one reboot), then I can run the MMC utilities for an hour or so, but then I get this error again on new utilities that I try to open.  The currently open ones continue to function.  And, this is a fairly new installation of only about two months.

Run ProcessExplorer on the server.

Note the time that the error happens and correlate that with the ProcessExplorer log.

It should indicate which component is not registered, then you can use the regsrv32 command to register the DLL if it is one, or at least find out where to go next based on the component.

Well, I'm back working with this server again...  I loaded processor explorer as a startup item, but haven't been around to see when I start getting the error...  I'll keep trying.

Reinstall SP2 for Windows Server. Something might have broken during the previous install.

That's not a bad idea.  Will re-installing SP2 mess up the Exchange SP2?  Actually, now that I think about it, I believe Windows SP2 was installed after Exchange SP2 anyway.  I'll give that a shot.

I don't know when I'll have time to get back to this server.  Thanks for your advise, though.
