According to, WMRUNDLL.EXE comes with the Novell Client for Windows NT/2000. It is copied to C:\WINNT\SYSTEM32 during the install of the client when Workstation Manager is selected. The function of WMRUNDLL.EXE is to act as a buffer between Workstation Manager and the helper .DLL files (WM*.DLL). If a particular helper .DLL file crashes for some reason, it is the responsibility of WMRUNDLL.EXE to keep Workstation Manager running instead of letting Workstation Manager to crash altogether due to the crash of the helper .DLL.
