[ActiveDir] DNS Registration issue

[Creamer, Mark]

I have a ISA server, which is also a DC for its subdomain, isa.mycompany.com. It has AD-integrated DNS. It is dual-homed, although both interfaces are “inside” our firewall. NIC #1 handles the requests from the production subnets and NIC #2 forwards the requests to the firewall to retrieve Internet content.   I’m noticing that even though yesterday I unchecked “Register this connection’s addresses in DNS” on NIC #2, and deleted the NIC #2 IP address on the name server tab, both addresses are showing up there again today.     Also, in DNS, under properties for the server, on the Interfaces tab, I had changed it to listen only on NIC #1, but today it’s back to listen on all IP addresses.   Any idea why these things would keep changing back?   Mark Creamer
