Multihomed Domain Controller readding DNS entry Marty Mash 5/3/2007 7:31:01 PM I hope someone can help with this situation. We have 2 DCs in our office and 2 DCs in another office on the other side of the state. The Domain Controllers in our office have 2 IP addresses assigned to the NIC. 192.168.1.x and 192.168.3.x. In the TCP/IP advanced properties we have the "register this connection's address in DNS" unchecked. Yet when I look in DNS both the .1.x and the .3.x address show up. The servers are Windows 2003 R2 SP1.

Yes, this behavior is by design, and it can cause many issue with domain controllers and is why it is not recommended to multi-home domain controllers; it can be done, but requires extra configuration. From you description, it sounds like you have both IP adddresses on the same NIC, which presents another problem, (Unless the subnet mask is 255.255.252.0) which would put both IP address in the same subnet. Unless you have defined the mask as noted you have to make sure that ONLY one of these IP addresses gets published in DNS. 272294 - Active Directory Communication Fails on Multi-homed Domain Controllers http://support.microsoft.com/default.aspx?scid=kb;en-us;272294&sd=RMVP -- Best regards, Kevin D.
