SYMPTOMS
When a non-administrator opens a file from within an application such as Microsoft Paint, an access violation (AV) could occur causing the application to terminate.

Restarting the system is required to clear the problem. The AV occurs in the MFC DLLs. The problem does not occur if the user is an administrator.



CAUSE
If Shell32.dll is invoked before Rpcss.exe, shell calls CreateEvent to create a certain event. An incorrect parameter passed on this call adds restrictions (security) on the event object.

The problem does not occur if Rpcss.exe initializes first because the right parameters are passed on the call to create the same event.



RESOLUTION
To resolve this problem, obtain the latest service pack for Windows NT 4.0 or the individual software update. For information on obtaining the latest service pack, please go to:
