I have been working tirelessly on upgrading our domain's functional-level to 2008. I have run into an issue with DNS that I can't seem to figure out. I have 2 domains in my company. The domains are not in the same forest and are not trusted amongst each other from what I can tell.
I have 6 total domain controllers - 2 for 1 domain and the other 4 for the 2nd domain. 2 of the domain controllers are brand new and run windows 2008. The others are a mix of 2k and 2k3. So the problem is that a previous admin was somehow able to get DNS on the 4 existing domain controllers to handle all DNS for both domains.
on the following DCs If I go into the DNS management console I can see both domain's DNS entries.
I need to replicate this on DC5.DOMAIN.COM and DC6.DOMAIN.COM so that hosts in site A can resolve addresses in DOMAIN-A if their primary DNS servers are DC5 and DC6.
I am using windows AD integrated DNS.
