How can I stop DNS registration of a secondary NIC on a domain controller?

I have two DCs on a network of servers in a co-location facility. The colo requires each server to have a second NIC for monitoring purposes. These secondary NICs are on a completely different, isolated subnet. There should be no traffic between servers on this subnet. The problem I am running into is that the two DCs are registering both of their NICs in DNS as valid resolutions for the domain root. In other words, a DNS query for "domain.local" returns four results:
192.168.123.2 ("real" interface of server1)
192.168.123.3 ("real" interface of server2)
10.128.214.72 (monitoring interface of server1)
10.128.214.73 (monitoring interface of server2)

I think this might be causing problems for me.
How do I tell a DC to only register certain interfaces with DNS?

Open the properties of the DNS server, and make sure the DNS service is only bound to the 192 address.
A DNS server will by default register all addresses it's listening on, even if the "Don't register ..." box is ticked.

got to the external nic - tcp/ip properties - advanced - DNS tab and at the bottom uncheck "register this connection's addresses in DNS"
