We have a Windows 2003 Server SP1 (Terminal Server). When we install the
4.91 SP1 client and change the Novell client properties "inital novell
login" to Off, the server will not process terminal services sessions. A
user will start to login, it will get about halfway through the login
process, then close the session. Afterward, this error appears in the
Event Log:
Reporting queued error: faulting application winlogon.exe, version, faulting module ntdll.dll, version 5.2.3790.1830, fault address

This only happens if the client is installed AND we change the "inital
novell login" property to off. It's like the nwgina.dll cannot process the
request correctly and crashes winlogon.
