New Compaq tc4200 tablet wireless

Window XP SP2
Having problems logging in after installing the Novell client to this computer. I did disable the firewall in XP and set the server IP address in the computers host file. After all of that it just hangs at the log in screen.

Tried using an older client 4.9 sp1a and the same thing happens.

This is our first wireless laptop and the first experience with problems with the client.

Any suggestions?
