We have 16 2003 domain controllers all of which have DNS loaded on them. We have setup a conditional forwarder on 1 of our domain controllers and it points to another domain's dns servers. When we are on the domain controller that the conditional forwarder was setup on we can ping the domain with no issues. When we are on any other domain controller in our domain, we cannot ping the forwarder address, even though it does show up in forwarder under the domain controllers properties. It looks like the forwarder was propagated to the other dns servers, but it is not working as it should. Any suggestions would be appreciated!!!
