Server: Netware 6.0 sp5
Clients: Windows XP sp2, Novell Netware Client 4.91 sp3

there are four servers in the specified context. In the client properties
I've entered the tree, context and servername. In the login window are these
values too, all the same.

'Sometimes' I get an error "LOGIN-LGNWNT32.DLL-890: server unknown", and the
workstation connects to a different server in this context.

How can I prevent this automatic connection to a different server than

The user should only connect to the specified server as his primary
connection (yes, he has rights to connect to the other servers but they
shouldn't be the primary connection). If this server is temp. not available,
the user should get an message, but no automatically login to an
alternatively server.
