Can't connect to Windows Update Server 3.2

bobohost used Ask the Experts™
Hello all

    I have a client that runs a Windows 2003 server with Windows Update Server 3.2.  Has been running just fine until today.  Now when they launch the snap in they get an error that it can't connect to the server.  I restarted the Update Services service but that did not work.  I checked the event log and I have the following error:

Event Type:      Error

The WSUS administration console has encountered an unexpected error. This may be a transient error; try restarting the administration console. If this error persists,

Try removing the persisted preferences for the console by deleting the wsus file under %appdata%\Microsoft\MMC\.

Well tried the first link.  Made those changes and deleted that WSUS file. I launch the Windows Update Server Snap In and it asks me What Server to connect to.  I type in the server info which is the same system and it pops out an error that it can't connect.

I would uninstall iis and and wsus without out deleting any data(asked during uninstall) and reinstall iis, and wsus


Ok I have uninstalled WSUS and will start the reinstall later today.  


Sorry for the delay.  We had to uninstall the entire program and do a fresh install.
