NW 3.2 and client 4.91 sp1 on a W2K station - in a mixed NT/Novell

I need to stop attempts to log in as workstation only (and skipping the NW
parts whilst still allowing the Microsoft ones), and can see there is an
option to remove the box from the novel client. My question is ...if I
needed to gain access to a station whilst the server is unavailable, so need
back that workstation only option, how do I get it back having disabled it?
Is it available again when server is not - or would I need the server back
up again....
