I have a Windows 2003 server, multihomed with 2 NICs; both ip addresses shown up in our DNS server (which is the same computer), plus this computer is also our AD controller. I only want DNS to know about the 1st NIC's ip address.

I have done what is listed in the article below, but the 2nd NIC's ip address keep showing up after a while.

Go into the TCP\IP properties of the NIC you don't want to register click Advanced then DNS tab uncheck register this connection with DNS. Delete the record then run ipconfig /flushdns on the server.

The technet article on restricting the DNS server (which is the multihomed server itself) to listen to the 1st NIC only COMPLETES the solution....the ip address of its 2nd NIC disappears in DNS right after I set not to listen on the 2nd NIC.
