Open regedit and do a find on the {F4B.....}
string. The keys and values where this "GUID"
appears will give you clues as to what software
is causing the problem. DO NOT change anything --
just expand the keys and look.

There may be too-restrictive permissions on a critical
DCOM object on your system which is triggering
the crash. If so, reinstalling that software may
fix the problem. (I don't think this is a standard
Windows COM object, as that GUID doesn't
appear in any of the servers I just checked, but you
can do an in-place upgrade with your Windows Server
CD to repair any Windows DCOM registrations.)

You could also try running the component services
MMC snap-in (under Administrative Tools) and drill
down to see if the GUID key appears by value there. If
so, you can open up the permissions on it quite
easily.
