We are running a 2000 native mode network. I installed WSUS on a 2003 server a while back. Recently I promoted that server to a Domain Controller and gave it the 5 FSMO roles. Since WSUS wouldn't run any more on that server, I uninstalled it. The Windows Internal Database is still there so I am trying to uninstall it so I can do a fresh install of WSUS. I have tried opening the command shell and running the msiexec command, but I keep getting "The setup has encountered and unexpected error while Setting Internal Properties. The error is: Fatal error during installation." The only other advice I have found is to demote and repromote the server to remove the WID. Is there any other solution?
