Novell Client and Windows XP

Here's the issue. I have a Windows XP machine. I logon to a Netware eDirectory Tree with the 4.9.1 SP3 client. When I boot up, I get the NC logon. I enter my netware username/pass, and logon. It take me to the Windows Administrator profile/desktop. If I go to lock the machine, it uses the Windows lock not netware. How do I get a desktop to match the netware name, and use the novel client exclusively?
