Multiple DNS entries
Posted on 2006-06-15
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?
