In a test environment, I have two forests: abc.local and def.local. Within each forest, the downstream domains work fine.
I want to create a forest trust between the two.
I have VPN tunnels between the two, and I can ping the respective DC's.
abc.local has all 2008R2 boxes, and def.local has 2003SP2 DC's.
I don't know how to configure DNS to make this happen, which I think is necessary before I can create the trust. Do I just create a simple primary zone in each domain that contains only the Host A record of one of the DC's, or do I create a new DNS domain. If the latter, what do I assign for the SOA records?
In my configuration, dc1.abc.local is 192.168.33.10. For def.local, dc1.def.local is 192.168.2.10.
Thanks in advance.
