DNS Delegation

Hi,
I've got an AD child domain and when I created it I made an AD integrated
dns zone on the child domain with the same zone as the parent (domain.com).
I'm having a problem with the replication between the two domains and I've
read an article on the microsoft site that says you should delegate the
child dns zone to the child servers:

http://support.microsoft.com/support/kb/articles/Q255/2/48.ASP&NoWebContent=1&NoWebContent=1

On the parent servers I deleted the child.domain.com section and created
delegations to the two child DCs instead. On the two child DCs I want to
create a zone child.domain.com and put all of the existing records into that
zone. Is there an easy way to extract all of the data from the current zone
and import it when I've recreated the new child.domain.com zone?

Thanks,
Ronan

You will have to recreate all manually created records, the Dynamic records
will be automatically created by the netlogon service if you allow dynamic
updates on the zone.
You may have to run netdiag /fix to complete DNS registration.

Thanks Kevin, not the answer I was hoping for though - I've about 500
entries I'll have to manually create.

That is a lot of manual records, were you not using DDNS?

They're all unix boxes and domains for testing mail servers.

I've figured out a quick way to do it. In the DNS change the type of domain
from Active Directory integrated to a Primary Domain. This creates a file in
c:\windows\system32\dns called domain.com.dns. Save this file somewhere.
Delete the old domain and create a new domain called child.domain.com as a
Primary domain.

Open up the old domain.com.dns file and find the child section. Copy it all
and paste it into the end of the new child.domain.com.dns file. Then you'll
need a copy of vi for windows (http://www.winvi.de/en/). Open up the file in
vi and type:

:%s/.child//g

This removes all of the entries for .child (or whatever your domain is
called). Save the file. Open up your DNS server, right click on your new
zone and click on "All Tasks", then click on "Reload". Then go into the
properties of your zone and change it to Active-Directory integrated.

Happy Days :)

One thing that quick fix didn't work for was mx records or aliases, when I
removed the .child from the dns file my mx records changed from
mx1.testdomain.child.domain.com to mx1.testdomain.domain.com and I had to
manually change them back.
