I have configured the DMZ on a PIX 515 firewall.
I installed a Windows DNS Server in the DMZ in its own AD Domain.
I can resolve Internet IP addresses but I cannot resolve hostnames to IP.
My DMZ DNS Server is using the ROOT Hints and my ISPs forwarders.

Thank You

Can RARP packets go thru firewall?

OR:
DNS reversive lookup zones seem to not work.
How is your DNS server configed?
Is that server using Active Direcory Integrated Zones?
AD Integrated Zones can set reversive lookup zones automatically.

Also, check SOA, NS, A, and SRV records for replication issues.
