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?
