Recently I added a second network interface to my Domain Controller, and assigned a private subnet to provide a iSCSI volume for backups, but the IP address from this interface is being propagated to my DNS server.
So now, when I use
nslookup against my domain, one of the responses is this private IP address.
How can I prevent this interface from updating DNS with its IP address?
This is a Windows Server 2012 R2 Domain Controller that's virtualized through XenServer 6.2 SP1.
