Parent Domain Can Not Resolve DNS Queries About Child Domain

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.local as 10.240.48.2 even with an NS record and an A record.

Under touchdown properties, I have the correct FQDN, but it can't validate the IP address.

Check if setting up conditional forwarders would help in yuor case. Set up conditional forwarders in both domains and check again

How to do that, you can read there

I've tried that, and I get a timeout occurred during validation.

Can you verify if there is no firewall blocking port TCP/UDP 53 ?
If not, please run on a DC in any domain in command-line''

dcdiag /e /c /v>c:\dcdiag.log
and
repadmin /showrepl /all /verbose /intersite>c:\repadmin.log

and post it here for analyze. Thanks in advance
