I have a Windows 2000 SP4 machine with Novell client 4.91 SP4. Got error
"Tree not found" when try to login to the NetWare 6.5 Sp5 network. Took me
a long time to troubleshoot and it turned out VMWare which creates the
WMWare virtual LAN connection that caused the problem. As soon as I
disable the VMWare network connection, I was able to login without problem.

Checked the Network connection, Advanced > Advanced Settings and the
"Local Area Connection" is before the 2 VM virtual LAN connections.

Does anyone know a solution that makes VMWare works with Novell client.
