This is a crock! The first thing the Win2K workstation must do is check for an existing name same as it used to do with a NETBIOS claim-name call.

I can only guess that you have overlapping zones of authority in your namespace.

With a proper implementation of BIND (or Win2K DDNS) the conflict is detected, the registration is refused, and the client system will note the conflict in its errorlog.
