Question : Making Novell the Primary Logon Client

Since I installed 2x onto my clients, the windows logon screen has taken over from the Novell Client Logon screen. Although the user is still able to logon without any issue, I would prefer the Novell Client to be the Primary Client to appear for logging on and not the Windows Client Logon Screen.

Answer : Making Novell the Primary Logon Client

I hope you mean client 4.91, not 4.61! That's about 8 years old. It's in the advanced options of the client - primary logon.

Alternatively it can be modified in the registry:
HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon
GinaDLL REG_SZ C:\windows\system32\nwgina.dll
