on one network with only netware 6 sp5 servers I can login vom Vista with
the Vista-Netware-Client (beta) without problems.

on another network with only netware 5.1 sp6 servers, I can't. I can ping
the servers vom the vista ws (32Bit), but if selecting "trees" in the
advances area of the login window, the list is empty.
From the WinXP stations with novell netware client "IP only" there is no
problem connecting to the netware 5.1 servers.

Are there any modules I have to load on netware 5.1 for the novell netware
vista client?
