W2K should not be doing this in this first place.  Allowing any system to update
DNS is dangerous.  Dynamic update should be the responsibility of the server
issuing the IP addresses.  It's a fundamental flaw of Microsoft's implementation.
Having only one server updating DNS means that you can limit update access
to that server and other maintenance systems.

I took the time to turn off all attempts to send registration requests to my DNS.
It was not easy to do, since Microsoft seems to think that you shouldn't do that.

That sounds like the right way to go.
