I have two nets. 192.168.1.x and 192.168.2.x. My 192.168.1.x hosts my DC with primary DNS zone (domain.org) and AD. I have the nets connected by VPN. What zone file should I use for my 192.168.2.x net. The DC on 192.168.2.x, I installed on as a additional domain controller within the same domain.org AD Domain. It replicates fine with the DC on 192.168.1.x. What zone type should I use and what zone name can I use? I have not had time to finish my MCSE yet so I'm designing and learning as I'm going along. The DNS is my last piece of the puzzle. I have DHCP on the 192.168.2.x DC and the DNS is setup for the 192.168.2.x, then 192.168.1.x and then the DNS of the ISP's.
