You may have a corrupted DCOM database.  (I had the exact symptom you 
describe and this is what the case was).  It seemed that a network install 
of Windows 2000 Service Pack 3 (In your case 5), either snafooed up the 
DCOM database, or 
redid the DCOM default settings.

I followed the steps in Method 1 of the attached link and everything 
worked perfectly! (After rebooting)

If you need anymore insight, please email.  I might be able to assist.
