Exchange server creating dns records automatically. How to stop

Question

We have 3 exchange / active directory servers.

exchange.queensberry.com exchange2.queensberry.com exchange3.queensberry.com

In the domain 'queensberry.com'

Our web server is remote from the network, www.queensberry.com but we want to change it to queensberry.com

The problem is that the DNS on the above servers is automatically creating 'a' records for "same name" with the internal ips of those servers. x.x.1.20, x.x.2.20, x.x.3.20 and there is also my record for the external server.

The problem is that on each lan the ip address being returned is for the local active directory server not the external web server.

Can anyone please tell me why these records are being automatically and how to fix/stop please.

Thanks Stephen

Domain controllers always register A records for the name of the domain (queensberry.com) with their own IP address.

This is by design and should not be tampered with under any circumstances. This is primarily required in order for domain members to find the SYSVOL share.
