Dual Network profiles.

I have a user that is running W2K on his laptop and he travels alot. He came to my location recently from another location that is running a Novell 4.12 shop. I am running an NT 4.0 shop with multiple domains. The migration/integration of the two different locations has not been seemless, nor is it complete and I don’t know when the “gurus” will resolve this. His novell login has access to the same exchange servers and the NT login.. Is it possible to setup dual profiles or dual LAN connectionsand simply enable and disable and if it is possible, How?? Thanks
