2 new XP Pro SP2-WS cause problems at server login (Netware 4.11). The
tree will be found, but seconds after I attempt to login the WS reboots.

When I just login into the WS and do the Netware login later, it works
fine. Last weekend when the first of both WS was completed, the server
login didn't cause any problems for very many times. When I uninstall NW
Client and use MS Client for Novell instead, login works as expected.

Should I refrain from using NW Client?
