i see things in several different ways.  the conclusion point two is
supposed to be absurd.

... which i am.  and due to microsoft, security on this issue is totally
out the window, and there's NOTHING that can be done about it except to
ban users from setting up unauthorised NT-Domain-Compatible PDCs.

sorry, not possible.  ok, maybe you can come close, but it requires
active monitoring.

for example, you use samba as a WINS server. you modify the source code in
nmbd such that it monitors for registrations of DOMAIN_NAME<1b> and
DOMAIN_NAME<1c>.  you run one of these "monitors" on each of your
broadcast-isolated subnets.

you can then either email / page the administrator or run
denial-of-service attacks against the offending server to take it down (a
drastic and not highly recommended course of action).
