Some DNS confusion, any clarification deeply appreciated.

Configuration: Three child domains (all Native Win 2003) - rem01, rem02, and
rem03.domain.internal and a root domain - domain.internal, each with two
DC/DNS servers. All DNS servers use AD Integrated zones with replication
scope to all DNS servers in Domain. Forwarders from the child domains to ISP
DNS for internet name resolution. Hub and spoke VPN from root to child
domains.

Question groups:

1. Should the Name Servers tab on each zone contain only the names of the
two servers in each domain and should you list only the "authoritative"
servers for the domain on this tab? Is this list in a priority order?

2. Stub zones on each DNS server for the other three (2 child and 1 root
domain) zones will work for name resolution between hots in different
domains? Is any other configuration needed to make stub zones work such as a
forwarder to each child/root domain? Should/can stubs be AD integrated?

3. Will zones configured as "AD integrated - Replication to all DNS servers
in domain" show up in the DNS GUI tool only under the DNS servers for said
domain? Another, way...I should not see fully populate zones in rem01 when
looking under rem02 DNS servers zone for rem01...I should see only the stub
with name servers for rem01 zone?

4. Is it possible to "transfer" a zone from an AD integrated zone to a
non-AD integrated "secondary"? If not, is the "zone transfer" tab totally
useless with AD integrated zones?

Many thanks.
