Hello, We currently have Two DC's that are configured with Active Directory integrated DNS. Although everything "works" we sometimes have a problem where when trying to resolve an IP on our network we're given their old stale address (an address they had a few days ago.). After doing some digging it seems as though our DNS servers are not replicating their cache with one another. Sometimes, the same listing may appear on both, but with different IP resolutions. It was my understanding that AD was supposed to handle the replication process.. is there something I should be looking for to aid in correcting the base problem? I'm not sure if my initial problem is caused by the replication issue or if it CAUSED the replication issue. It may be worth mentioning that one is running Server 2003 and the other is on Server 2008. Also, there is nothing abnormal in event viewer for either of them.
