I have an IBM Thinkpad running Windows XP pro SP2 and Novell Client
4.91sp2 that can no longer login to the network.

The NIC is working and I can ping the server, but cannot login using the
client Tree or server cannot be found.

All other workstations running 4.91sp2 are able to connect. Have
uninstalled and reinstalled version 4.91sp2, as well as earlier versions
without success.

There have been no changes to the server between the previous successful
login and now. User is able to login on all other workstations.

The only change I can see on this machine is the addition of a local
network connection (firewire port) created when user downloaded photos
using a highspeed cable device.

Any assistance you can provide would be greatly appreciated.
