I'm running a Microsoft DNS Server for AD. One of my Servers has two NICs and hence two IP Adresses ( and The IP Adresses are intentionally in different Subnets, the 1.10 shall only be used for administrative tasks.

The problem is that this configuration registers two IPs for the same Host with the DNS Server. When a client from wants to resolve the host name, it may be handed the wrong IP Adress ( There is (intenionally) no route configured between the two subnets.

How can I make the DNS Server hand the correct IP adress to clients? Can I prevent the 1.10 entry from being made?
