Netware and XP users

I have a computer with Windows XP connected to a Novell
Netware network. This computer is at a central location
and more than one user accesses the network from it. Is
there a way to login into the Novell client and not have
the workstation prompt for a local name and password? For
example, when anyone that is set up on the network logs in
on a computer with Windows 98 they get in, have the same
desktop and icons if I want. With the XP machine if a
users that doesn't have an account set up on the computer
itself does that, after the Novell logon clears you get
prompted with the workstation logon. Is there a way to
prevent that from appearing so anyone can use the pc?
Thanks.
