SYMPTOMS
After you install Windows 2000 Service Pack 3 (SP3), you may receive the following error message when you start your computer:

User Interface Failure:

The Logon User Interface DLL msgina.dll failed to load.

Contact your system administrator to replace the DLL, or restore the original DLL.

The Windows logon screen does not appear and you cannot open Windows 2000.



CAUSE
This problem may occur if Winlogon.exe queries the Mpr.dll registry key before Services.exe has created this registry key. In Windows 2000 SP3, Msgina.dll is dependant on Mpr.dll. Mpr.dll requires that the following registry key is present to be able to initialize:

This key is created when Services.exe starts. Because Winlogon.exe starts at the same time as Services.exe, Winlogon may query the Mpr.dll registry key before is has been created by Services.exe. When this occurs, Msgina.dll does not load and you receive the error message that is described in the &quot;Symptoms&quot; section of this article. This dependency does not exist in Windows 2000 Service Pack 2 (SP2).
