Child domain and DNS

Hello list. In a Windows 2003 R2 forest I've added with dcpromo a child
domain of my root domain.

On the Root's DNS, the child domain appears as a subdomain.
I'd like it to appear as a deleagate zone of the child domain pointed to
the child DC's DNS server.

my idea is
1. create the zone on the child DC's DNS by manually copying all entries
from the root's DNS
2. delete the subdomain on the root DNS
3. create a delegated zone in the root domain for the child zone.

Is it a good solution?
Is there any better solution with a 2003 (native mode) forest?

thank you.

Hello,
thankyou for the link but my child domain is already DC promoted.
if I dcpromote again it wants to remove active Directory.

How could I do that without uninstall the chlid's Active Directory?

Raphael,
apologies for lack of clarity - your high-level plan appears to be sound
(you actually can introduce the delegated zone in the step 2 - which will
effectively eliminate the subdomain and simplify creation of the glue
record) - my intention was to point out a couple of additional factors to
consider, which are included in the article. As you stated, the step
"Promote the Child Domain Server" does not apply in your case...
How many computers are currently in the child domain? Note that all DC SRV
records can be automatically registered by restarting its Netlogon service
once the delegation is in place...

Hello Raphael,

In my experience, it's not recommended to create Forward Lookup Zone of
subdomain on root DNS. You can delegate DNS query of root DNS for child
domain DNS, than config DNS forward of child domain to root DNS. For more
detail about DNS configuration, you can reference to the link below,
