Multiple DNS entries

A few days ago, I set up my backup system on its own network.  I changed the IP address on my backup server to a different subnet than my current network (is now 10.24.10.10) (current network is 10.24.11.0).  Then I set up the 2nd nic on each of 5 servers with a specific IP address on that subnet.  The first NIC on each is still 10.24.11.x and the 2nd NIC is 10.24.10.x.  Two of these servers are domain controllers and DNS servers.  These are all on their own gigabit switch.

What has happened, on these two servers, there are two entries in DNS, one for 10.24.10.x and one for 10.24.11.x.  The 10.24.10.x is showing up first on the list.  Now, some users are picking up the 10.24.10.x network and when trying to access applications that call the server name, it is trying to send to the backup network and never getting to the server.  If I set their pathing to the IP address instead of the name, it is fine, however, I have many, many users and applications.

Is there a way to get rid of the 10.24.10.x entry and not have it repopulate or possibly make the 10.24.11.x entry a priority?

Assuming those machines are running W2k3 SP1, uncheck the "Register this connection in DNS" on the "backup network" NICs, delete the according entries from DNS and make sure they don't come back.
For W2k and W2k3 without SP1, check these articles:

Clients cannot log on to domain controllers that are Windows Server 2003-based DNS servers, and network interfaces that are not registered in DNS can still perform dynamic updates
