windows-server-2008

Hi,

We've got a build server (Windows Server 2008 SP2, 64-bit) which has one NIC and two IP addresses registered to that NIC (192.168.1.30 and 192.168.1.31). The build server is registering two identical Host (A) records for itself in our DNS server:

buildserver.example.com => 192.168.1.30
buildserver.example.com => 192.168.1.31

I know in the "Advanced TCP/IP Settings" window for the build server's NIC, under the "DNS" tab, there is a check box labeled "Register this connection's addresses in DNS". I only want ONE of the IP addresses (ending in .30) to be registered in DNS not both of them. Can that be done?

My best guess is to disable the "Register this connection's addresses in DNS" and manually add the Host (A) record to our DNS server.

Thanks for any help!
