Can anyone tell me if this will effect the Client when they can't see the

I have set in ZENworks workstation package policy under the Windows
NT-2000-XP NT Client Configuration, the option to remove the Workstation
only option from the Client login prompt. I have several clients now walking
up to me and saying that when they take there laptop home it doesn't allow
them to log into the laptop. It was my understanding that they would place
the Novell username/password in and the client would try to log in but when
it couldn't find the tree provide the error stating that it couldn't find
the tree and ask if they wanted to log in locally. Is this not the case?

My goal is to force the students and teachers at the school to log into my
Novell network. One way of getting this done is to remove that component.
