We have 3 exchange / active directory servers.

In the domain ''

Our web server is remote from the network, but we want to change it to

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 ( 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.

See the following posts which discuss this situation:

Thanks Graeme. I find myself going grrrr at the organization that set up our active directory. I can see us changing the website now. But thank you – Stephen Baugh Aug 14 '09 at 10:51
You're welcome. You can give them some more 'grrrr' for putting Exchange on Domain Controllers, which is generally frowned upon. ;-) – ThatGraemeGuy Aug 14 '09 at 11:19
