It sounds like a bad installation of the O/S.
If you have the install CD, you can do an upgrade over the top of the
existing O/S to see if that corrects the situation. It will not cause any
exiting programs on the machine to fail. You'll need to apply the SP and
Hot fixes again.
You should have an O/S that is fully functional, IMHO.
It may come down to doing a fresh install of the O/S as the final
solution.
Search Google and the MS Knowledge Base for possible solutions.
