SYMPTOMS
When you use Windows NT Workstation or Server version 4.0 and select the Last Known Good configuration option, your computer is set back to post install settings or some installed services are missing. This symptom can appear identical to the following Knowledge Base article:

136441 Last Known Good Always Restores Original Boot Settings



CAUSE
This can be caused by the Intranetware Client for Windows NT Workstation version 4.1. Since the client replaces our GINA by using it's own gina.dll (Nwgina.dll), it never updates the Last Known Good Control set in the registry. So when you choose last known good, your computer gets brought back to the state it was after initial setup, or the point you installed the IntraNetware Client. To verify this is the problem, do the following:

WARNING: Using Registry Editor incorrectly can cause serious, system-wide problems that may require you to reinstall Windows NT to correct them. Microsoft cannot guarantee that any problems resulting from the use of Registry Editor can be solved. Use this tool at your own risk.   Start Registry Editor (Regedt32.exe) and go to the following subkey:

     HKEY_LOCAL_MACHINE\Software\Microsoft\Windows NT\ CurrentVersion\Winlogon   Look for the key GINADLL, and verify that it has the following value:

     REG_SZ:NWGINA.DLL  If the above value is present, this is what caused Last Known Good to fail.



RESOLUTION
None at this time; Novell is looking into the problem.



MORE INFORMATION
The Intranetware client installs on Windows NT and logs the workstation onto a Netware 3.x or 4.x server, then logs onto a Windows NT server computer. The Novell Nwgina.dll handles this task.

For more information on how Controlsets and Last Known Good Configuration is handled via the registry, see the "Windows NT Workstation Resource Kit," Chapter-36 Pages 1051 - 1053.
