That is correct. After you delegate a zone to a child domain the dns servers
in the child domain will be authoritative for the child domain, however they
may not be able to use recursion to find the parent domain unless the top
domain in the forest tree is configured to be the root domain and the child
domain controllers have their root hints configured with the domain names
and IP addresses of the dns servers authoritative for it. See the link below
to a KB article on AD dns FAQ. With Windows 2003 conditional forwarding and
stub zones can often be used in place of secondary zones if you do not need
the redundancy or load balancing of secondary zones. --- Steve

Question: How do I set up DNS for a child domain?

Answer: To set up DNS for a child domain, create a delegation record on the
parent DNS server for the child DNS server. Create a secondary zone on the
child DNS server that transfers the parent zone from the parent DNS server.
Set the child DNS server to point to itself only.
