SYMPTOMS
When you use the Citrix ICA client and are connected to a server configured using the Metaframe add-on to Microsoft Terminal Server, you may receive a Dr. Watson error in Spoolss if using the HP LaserJet 4000 printer.

  Application exception occurred: App: exe\spoolss.dbg (pid=74) When: 9/14/1998 @ 14:28:14.841 Exception number: c0000005 (access violation)



CAUSE
This issue may be caused because you may have a mismatched version of the Hpdcmon.dll file, or the Hpdcmon.dll file may be corrupted, or it may be unnecessary for proper operation.



RESOLUTION
Remove the dynamic link library file named Hpdcmon.dll from %SystemRoot%\System32 folder. If it is not found in this folder, perform a search of your %SystemRoot% folder including subfolders, and remove it from any folder in which it is found.



MORE INFORMATION
Hpdcmon.dll is a port status monitor that queries the parallel port for incoming information. Not all versions of Hewlett Packard's printer drivers require this library file. Check with Hewlett Packard for more information on using this file with the printer driver being used.
