The NWLink internal network address should be set to 00000000 but, having
manually set it to 00000000, after restarting the PC the internal network
address has changed to an apparently random hex number (it's different
every time). I have removed and reinstalled the Novell client 4.83sp1e but
this has not helped.

No other PCs on the network are acting like this and I can't work out where
it's getting this random internal network address from.

Any ideas appreciated!
