Windows 2K DC A Record Visible When Running Nslookup against doma in name

I've noticed this as well. Or suspicion is it's just MS's way of taking
control of the zone. It does not overwrite any existing A records, but we
did not want our DCs populated this way and have disabled updates to the
primary zone file. We did create _msdcs, _tcp, _udp, and _sites subdomains
under the primary zone and allow the DCs to update those zones. AD/Win2K
clients find their DCs from those zones.
So far so good, although we have not yet migrated this setup into our
production network. Want to test Bind 9 first.

Hi...
I've noticed that two and I think it's because the W2K DC's create A records
associated with the domain itself as well...why, I don't know (I seem to say
that a lot about Microsoft), but then again we're just starting to set up a
testbed...probably how AD clients find their DC's ???
