Windows 2003 standard server and novell 6.5

Running windows 2003 as a workgroup server. I'm trying to
map a drive to a novell 6.5 server. The netware server is
setup as "ip only". I can ping the netware server from the
win2003 server by name and ip. Tried uninstalling and
reinstalling client services for netware off the win2003
server but still no go. Is there anything else I need to
do on the windows 2003 server in order for it to
authenticate to the netware server? Any help would be
greatly appreciated.
Thanks
