Win2K, BIND & Multi-master

Hello all-
I've got a consultant here telling me that BIND can be set up with a
multi-master model.
I've been trying to get it to work (for several days), but everything I
currently know about BIND 8.2.3-REL goes against having multiple
masters.
Test #1: I've configured just 2 servers. A test domain -on server 1 is
configured as "master",
on server 2, it's a "slave". Using nsupdate, (while on DNS server #1) -
I add a record, the master sends a NOTIFY, it's received, the slave does
a AXFR, -and all's well.
(I'd like for it to do a IXFR... I can't figure that out either!)
Test #2: I've configured just 2 servers. A test domain -on server 1 is
configured as "master",
on server 2, it's also a "master". When using nsupdate, again -on DNS
server #1, it sends the NOTIFY to server #2, but [I presume 'cause it's
also a master] I get:
notify: info: NOTIFY(SOA) for non-secondary name
...and, as expected, the second "master" server ignores the update from
the "true" master.
I've been playing with "notify yes;".. and that doesn't make any
difference either.
My goal is to find a way to get BIND 8.2.3 replication-model to mimmic
Win2K's DDNS. I need to allow for multiple company sites to each have
their own master for ....say... the adaptec.com zone. If a Win2K client
in one site does a dynamic update- it'll update the DNS server specified
in the clients DNS settings... right? That would be their *local* DNS
server.
Any ideas on how can I get the other "master" DNS servers to see their
update (and do IXFR's)?
Thanks in advance-
John
