Just to make sure I understand:

1) Is your 2003 DNS server going to an exernal DNS server and attemping to get a zone?

Or

2) Is a external BIND DNS server attemping to get a zone from the 2003 DNS server?

Either way, the DNS server that is the authoritive (source) may be configured to only allow zone transfers to specific server, by IP address.  So you need to make sure that the DNS server that is the source is configured to allow your DNS server to request a zone tranfers.

Hi


Make sure that named.conf has:  allow-transfer {IP of 2003 DNS server; }; in the options section, and that 2003 DNS is configured to retrive DNS updates from the BIND server (mentioned above by bleeuwen ).

Also TCP is used instead of UDP for zone transfers, make sure your firewall is configured to allow TCP port 53

Are you using TSIG etc to secure the DNS transfers?
