Having some trouble with an external domain trust. The networking portion is functional as I am able to ping ip addresses in both directions but I cannot ping host names from one side of the trust but I can ping hostnames from the other.
Conditional forwarders are validated and FQDN resolved.
Two Way External
Both sides are 2003 functional level
I am able to ping hostnames from DomainA (from any server) on DomainB however, I cannot ping hostnames on DomainA from DomainB. I can ping ip addresses/
This trust was functional at some point in the past but disabled - I don't think zone transfers/secordary servers were used but and I swear I was able to ping hostnames in both directions just a few days ago.
