Spooler service keeps dying

[Rob]

Windows 2000 Server SP3, Terminal Services, Citrix
Metaframe 1.8.

The Printer Spooler Service keeps dying. It will run for
a couple of hours then die. I can start it right back up.
System event log says

The Print Spooler service terminated unexpectedly. It has
done this 8 time(s). The following corrective action will
be taken in 0 milliseconds: No action.

Can anyone give any insight on this?

Thanks!
