Dual Homed Domain Controller DNS Issues

[Arc J. Thames]

I have a domain controller that has 2 NIC's in it and is also running DNS.
One of the NIC's is connected to our production LAN, the other is connected
to our back-up network that we use to run backups on the servers. I have
gone into the NIC properties on the backup LAN and told it not to register
itself in DNS, however it still puts a record in it's own DNS for that
backup NIC. Does anyone know of a way to stop this? The backup NIC is not
on our production LAN so therefore if somebody resolves to that IP, they
can't connect. Any help would be greatly appreciated.

The dynamic update gets performed by three services; DHCP client, DNS server
and Netlogon. This kb explains how to disable dynamic registration in each
case. You will need to do all three.
