DNS Server config in forest

[tavie]

I have looked all over the internet and I cannot find any good examples for my situation. I am having some DNS resolution and zone transfer problems and I think it may be related to how DNS was configured. We have two root DC's at the top level of our domain and three child Domains....The IP addresses are just for reference

/ / \ Root DC's(ip 10.10.0.17 & 18)
/____\
/ / / /\ /\ / / \ / \ / / \ / \ / ------ ------ ------
Child1 Child2 Child3
(10.10.1.1) (10.10.2.1) (10.10.3.1)


My concern is that All Child domain controllers should reference themselves first as the Primary DNS server and reference another DNS server that exists in it's same child Domain. When I do this Nslookup fails for a multitude of PC's and servers on the nertwork. When I set the root controllers as the Primary DNS(10.10.0.1) then resolution seems to work better but zones still do not seem to update properly on the roots. The roots contain secondary zones of all the child domains but they seem incomplete...Zone transfers do not seem to be complete between DC's in the same child domain as well. I was wanting to know what the best practice is for DNS settings...Which one should be Primary and Seconday and do I need to include all the DNS servers in all the Domains in the DNS Tab ??? Thanks...Tim

The root servers should be listed in the root hints tab of each child.

The children should reference themselves for primary and secondary, just put the root servers in the root hints list of each child. How are the zones setup?

Dynamic updates are on a per zone basis .....

tavie, you might want to check out DNS/BIND/DHCP/WINS Issues forum. The way I've always set up dns is first a dns server points at itself. If there is dns server in the same domain, add that also. Then for redundancy, add more dns servers either at the root, if you have a root child set-up, or at you're isp if don't.

If the child zones are setup for DNS delegation does this change anything???
