SYMPTOMS
After you remove an unsuccessful installation of Novell NetWare Directory Services on a primary domain controller (PDC) running Microsoft Windows NT Server 4.0, you may be unable to log on to the PDC and you may receive an error message citing Error C00000DF.



CAUSE
This behavior can occur when the files Samlib.dll, Samsrv.dll, and Winlogon.exe are the incorrect version.



RESOLUTION
To resolve this behavior, update the relevant files. Follow these steps:

 Perform a parallel installation, including the same service pack that is installed for the original installation. Start the computer to the parallel installation. Start Windows Explorer, and then view the following files to see whether their date/time stamps are correct for the service pack installed for the original installation of Windows NT:

Samlib.dll

Samsrv.dll

Winlogon.exe

 Rename any of these files that do not have the correct date/time stamp, and then replace them with copies from the parallel installation.
