We have one server that exists outside our cluster which we use for many back-end tasks, but most importantly, it acts as a backup Active Directory Domain Controller in case the cluster ever goes down. The problem is, that it has to have 2 additional network cards so it can communicate on our Storage and Voice Vlans, as well as our computer Vlan. Because of this, it automatically, and continually populates all 3 of it's IP addresses in DNS.
I have disabled registering of DNS of the two additional network cards, yet their addresses keep appearing. This is interfering with AD replication.
Can someone advise how I can stop the two additional network cards from populating these extra DNS entries for that server?
