Logon to the print server with Administrative priviledges. Close the Printers
Folder. In Control Panel / Services, browse to the Spooler service and stop it..
If you are using TCP/IP Printing Services, stop it also. Delete the .spl and
.shd files from %SystemRoot%\System32\Spool\Printers
that have the approximate time and date of the print job causing the
problem. Restart the sevices that you stopped.
NOTE: In some cases, Windows NT may not allow the *.spl file(s) to be deleted
or renamed. Renaming the *.shd file and restarting the spooler service may be
enough to clear the problem.
