I have domain.local on my PDC, and on my newest DC at a remote site I created touchdown.domain.local as a child domain in the same forest. I ran DCPromo and the child domain can resolve DNS from the parent and it is a domain controller. However, I can't get replication going because the parent can't talk to the child. The parent is at 10.240.0.2 and the child is at 10.240.48.2. The parent DNS does not acknowledge server2.touchdown.domain.l<wbr />ocal as 10.240.48.2 even with an NS record and an A record. <br />
<br />
Under touchdown properties, I have the correct FQDN, but it can't validate the IP address.<br />

The Domain Name System (DNS) is a hierarchical, globally distributed system responsible for associating the name of a computer, service or other resource into an IP address for connecting to the Internet or a private network. Most prominently, it translates domain names to the numerical IP addresses needed for the purpose of computer services and devices worldwide.
