Windows 2000 server not functioning, no admin apps working..

Archived from groups: microsoft.public.win2000.setup_deployment (More info?)

Last Saturday our Windows 2000 Server (5.00.2195 service pack 4) would not
restart, since the boot drive is mirrored, I swapped the drives around and
was able to get the OS to boot. Now, however, none of the applications on the
Server, Norton Anti-Virus Corporate Edition, Veritas backup Exec for Windows
Server v 9.0, work. I also cannot use the Administrative tools to diagnose
problems, nor start the Disk Manager to attempt to re-synchronize the drives
to see if Registry is the problem
