Separate DNS in remote Office

I have a Windows 2003 domain controller in a remote office.  It also has DNS and DHCP for that office.  Here's my situation.

At our main office I resolve www.ourdomain.com to the DMZ (10.0.10.10).  The remote office needs to resolve www.ourdomain.com to the external ip, such as 123.123.123.123.  

My DNS server in the remote office is set to replicate with our DNS server at the main office.  How do I create a separate DNS zone for my remote office?

Hi!

Go to DNS console, to forward lookup zone and add A host record for www.ourdomain.com which point si external IP 123.123.123.123.
Use the following command "ipconfig /flushdns" to clear local resolver cache and try again.

If DMZ is accessible from remote office you might want to add host record for web server with ip 10.0.10.10.

When I change the IP in the DNS console of the DC in the branch office, it changes the IP in the main office.  How do I configure it, so that it doesn't change the main office dns record?

Are you using AD integrated zones? If so, the contents of the zone is replicated and you can not have  two different records. In this case you wolud have to change hosts file on all clients in remote office. How many clients are we talking about?

I am using AD integrated Zones.  I can change the hosts file, but that seems very cumbersome.  Can I remove the remote dns from AD integrated, so that it doesn't replicate?  How do I do that?

Unfortunately not, DNS data has to be replicated. You could host two different primary zones (in theory) but it's bad karma. Hosts files can be manipulated with simple start up script, which will copy file from server.

I removed the DNS zone from AD and added a non-AD primary zone to each server at each site.
