How do I set up Login Batches?

I have a NT server that I am taking off line, so I need to set my authentication process to our Win 2k server. How do I set yp the login batch files so the users automatically map their drives properly?

Also, while I am at it, is there a way to port over all the user information between my PDC NT 4.0 box and the Win2k server?

Thanks.
