Thanks for the response. Very helpful. The reason that I did not consider Conditional Forwarding appropriate was that I received an error when I tried adding a forwarder for subdomn.example.com to the example.com Windows 2003 dns servers. The error was "The server forwarders cannot be updated. A zone configuration problem occurred". I am guessing that it is because the example.com domain has a mix of Windows 2000 and Windows 2003 DNS servers (we are running in Windows 2000 native mode). I suspected that there should be no Windows 2000 DNS servers in the example.com domain for conditional forwarding to work and enable the subdomains to be resolved.
