Question : SBS 03 with AD/DC is automaticall re-generated A Host Records

Hello everyone, got an odd one for you all!

My company network is currently working off of a SBS 2003 with AD/DC/FS roles and acts as a DNS Server for the domain. Unfortunately, the person who setup the domain way back when used a .com extension, the same .com as our external website. So, I have been going into the DNS management console and deleting a Host (A) record that is the root set to the physical IP on our server. I have created a new root Host (A) record pointing to our actual external website.

I am also noticing that a Duplicate Host (A) record is being created with a random IP address to the FQDN of our 2003 server. So here is the map:

SBS 2003 @ 192.168.0.1 hosts the AD, DC & FS and is named exampledc.domain.com
Host (A) record for 192.168.0.1 pointed to domain.com
Host (A) record for 192.168.0.1 pointed to exampledc.domain.com
Random Host (A) record for 192.168.0.71 pointed to exampledc.domain.com
Host (A) record for domain set to external website IP address (along with a www. Host (A))

So I delete the incorrect records, but then they regenerate. Is there somewhere that I need to check to see what it is causing this?

Answer : SBS 03 with AD/DC is automaticall re-generated A Host Records

Exactly as cgaliher said really.

If you do this you will break AD. That record is used for DFS and Group Policy deployment.

You can work around the issue in a number of ways, the easiest is to have everyone use www.company.com rather than company.com to get to the web-page.

You might also set up IIS on the SBS server and have it redirect HTTP requests for company.com to www.company.com.

Renaming the domain isn't an option for SBS, it'd take a migration to change the internal domain name otherwise that'd be in the work-around list.
