2003 Server can't resolve DNS properly

Posted on 2006-06-26
Last Modified: 2010-03-18
I have 4 2003 servers with sp1 installed and 1 existig NT4 BDC which has exchange 5.5 stil installed on it. All mail has been migrated to the 2003 server.. 1 is a 2003 domain controller, 2 are file servers and the 4 is a 2003 exchange server. The exchange server isnt resolving dns properly.. All other workstations and servers are fine. I can ping by ip address, server name but not the FQDN on the 2003 Exchange server. All other machines can ping and recieve replies all 3 ways... As you can guess being an exchange server this is causing all kinds of problems.  Getting errors in the system event log (5790) No suitable doman controller is available for domain (mydomain). An NT4 or older domain controller is availabel but cannot be used....  It all seems to be caused by DNS not working properly... any suggestions?

POST your DNS Settings on the Server and on a workstation.

Thanks for the info.. Active Directory has seemed to be fine until exchange 2003 was installed and the mail was migrated... I know that Exchange 2003 needs dns to function and was pretty sure things were working properly.. I will post the info requested tomorrow when i get back to the office.

I just did a quick test to see if the problem would clear by running ipconfig  /flushdns and ipconfig /registerdns and this allows me to ping FQDN's from the exchange server and open the system manager and so forth.. the problem is that after 15 minutes dns replicates and all functions stop again from this server... Im pretty sure this tell me its a dns issue... Any suggestions

This is the Firewall (symantec enterprise firewall)... to allow users to access the internet if the 2003 primary dns server isnt available.

Please read the links I posted.

Your workstations and member servers should use ONLY the DNS of the Active Directory Domain Controllers.  The only backups they should use are the backup Active Directory DNS servers - if you only have one, then there should only be one.  Failing to do this can create all sorts of problems if, for whatever reason, your AD server doesn't answer first.
