 Last reviewed: March 17, 1998
Article ID: Q182562
The information in this article applies to:
  • Microsoft Win32 Application Programming Interface (API) included with:

    - Microsoft Windows NT 4.0

SYMPTOMS

The Screen saver fails to run, and the following error message appears: 

   Initialization of the dynamic library <system>\system32\user32.dll
   failed. The process is terminating abnormally.

CAUSE

A process applied a NULL Discretionary Access Control List (DACL) to the WinSta0 Window Station.

RESOLUTION

A process should not apply a NULL DACL to the WinSta0 Window Station. Either an access control entry (ACE) should be added to the existing ACEs in the DACL, or, if the DACL is replaced, it should contain at least one ACE.

For more information on adding an ACE to the interactive Window Station and Desktop, please see the following article in the Microsoft Knowledge Base:
