Question : Unable to bind in dns (Exchange 2003)

Hello, i have 2 DNS server's on my network. An internal and and external. The zones of those two are identical except the ip addresses of the records in the zones (eg: In the zone hellenic-net.gr the Internal server has a www record points to 192.168.0.X but int the external server it points to 80.76.47.X ip address). I dont use secondary zones or stub zones because i want to have them complitely independant.

Now, to the problem. I also have 2 exchange 2003 Server's which host about 5 domains each. The thing is that when a e-mail user of the first exchange tries to send e-mail to a user which has e-mail on the second exchange, the e-mail never arrives. I checked the queues and it report something about "unable to bind in DNS". I checked for the problem in MS and they say (if i understood it correctly :-) )that when an exchange tries to resolve a domain name it expect's an answer from the AUTHORITATIVE DNS Server for the Zone.

Any ideas ?? Sorry but i only have 250 points left :-(

Shame ;)

It only really leaves a configuration problem with the local DNS.

When they send messages between the servers do they use any one of the 5 domain names mentioned above?
