Dr. Watson

The Users in my firm get the following error
message in the event Viewer when they get the DR. Watson error message:
“The Open Procedure for service “McShield” in DLL “dssdata.dll” failed.
Performance data for this service will not be available. Status code
returned is DWORD 0.” Users get this message wheter they use the printer Icon in Word ’97 or in whatever they are doing it does not matter what they are doing in word 97 they get the Dr. Watson and Event Viewer gives them the same message. What does this pertain to?
