RE: [ActiveDir] DNS on dual-home machine

Title: Message

Well, "Right off the bat ..." as Joe would say, I'm interested in this thread.  I have a situation which off-handedly relates to this and I'm curious what the Brain Trust (capitalized personal pronouns out of sincere respect) have to say about it.  Here's my situation, not to difuse Mark's query.   I have a second Forest that has a one-way trust to my Primary Forest.  That Forest has a DC which holds all roles, a BDC and three Servers.  The DC + BDC are W2KS SP3.  The DC in my Primary Forest is the same.  The DC in the second Forest is multihomed and one NIC is on the same subnet as my Primary Forest, the other is on a 192 subnet.  I am finding that I cannot keep that DC up if I do not have both NICS registered in DNS to point to itself in the 192 subnet.  If I un-DNS the NIC that points to my Primary Forest or if I DNS it to register itself in the Primary Forest while the other NIC DNSs itself to point to itself in its own Forest, it goes offline and says it's not a DC.  You can log on, with Domain credentials but it events itself to death and shuts down the access to that Forest.   I would like to hear if anyone else has multihomed DCs and how they have them set up DNS wise, especially in a multi Forest environment.   Thanks, especially for all the advice in the past.  This list is "Mission Critical" in my book.  Finally one more question, "Where in He** do youse guys get the time to answer all "our" hairbrained questions anyways?"   Rocky Habeeb Microsoft Systems Administrator James W.

Both NICs have private addresses. One NIC is associated with domainA.com, which is an internal-only AD domain. The other NIC is associated with domainB.com, which is an Internet presence domain.   The problem is that on this particular server, *both* IP addresses are registering in DNS on the domainA.com AD domain. I only want the one address associated with that domain to register there.   So far, I have deleted the NIC from the Name server tab in DNS for that zone. A while later it comes back. I looked at the DNS properties for the NIC that I don’t want to register, and have un-checked “Register this connection’s addresses in DNS.” Still it re-appears.   Can I get some guidance on this? It’s only happening on one of these servers, not another one which I thought was identical in configuration.   Best regards, Mark -------APPLEBEE'S INTERNATIONAL, INC.
