fatum

I am wondering if anyone can think up a solution to this problem.. Im working for a school who runs a novell filesharing network. Every student (500 or so) has a unique username & password. At our current state we have students logon with the novell client. After that the Microsoft client comes up and students are forced to press enter again to login to a defaulted windows user. The problem is we would like to skip the windows login altogether, because it provides the students a way to possibly login without security settings in place.. How can I skip this windows login screen? Is there some registry mod? Login program manipulation of some kind? Script that is run before the windows login but after novell??
