We have a Windows Server 2003 Active Directory. We have Primary and Backup domain controller.
I am told that both have been set up to share certain tasks on the network, including login scripts, DNS etc.
Our internal network runs on 192.168.0.xxx and our ISP DNS servers run on 135.196.0.x
DHCP is setup on our Primary AD controller.
Much of the AD was set up by a 3rd party, and we were checking a few things recently and now have the following question.
Where should the external ISP DNS server information be placed ?
They are NOT listed in the DHCP server setup, so the clients will only list our internal 192.168.0.5 and 192.168.0.7 DNS servers.
It would appear that currently they are setup in the 'Forwarders' tab on the DNS Server properties. However, the ISP DNS servers will not be able to resolve our internal addresses, so this sounds wrong to me ?
Looking at the Forwarders properties on the Primary AD, our secondary DNS server is not listed.
Can someone advise ?
