Novell ZENworks for Desktops

Workstation Manager

fix

Workstation Manager creates a named pipe into WMRUNDLL.EXE. 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. Workstation Manager starts a separate instance of WMRUNDLL.EXE every time a helper .DLL is launched. This can be observed in Task Manager.

When WMRUNDLL.EXE starts, it calls an initialization routine in the helper that returns flags which tell WMRUNDLL.EXE whether to use user or system scope, and which helper entry to call. Based on the flags, WMRUNDLL.EXE can call 3 different entry points.

Novell's GINA will launch the DLLs located in HKEY_LOCAL_MACHINE\SOFTWARE\Novell\Workstation Manager\PredesktopHelperDLLs after the user has authenticated and login scripts have run, but before the user's desktop has loaded. This allows ZENworks to make changes to the OS that will be seen the first time they are set on user login.
