In addition to what Kevin Darcy wrote, let me add the following:

If I correctly interpret what you wrote, you have

     1) You have a BIND server as the master of the zone in question.
     2) Your firewall does not allow DDNS to that BIND server.
     3) You want DDNS to occur on the Windows 2003 DNS Server.

You should search the archives of this discussion group (and may be of
its late sister list, bind9-users), as there have been many W2k-related
postings over the years.

You do not give us your domain name structure.  If your BIND server is
master for

and the Windows client machines have names

then you will have to allow DDNS on the BIND server, or move the zone
to the W2k DNS Server.  You cannot have two masters for the

If your Windows client machines have names

then you can place the AD zone (along with the six AD-related zones)
on the W2k DNS Server and slave the zones on the BIND server.
