We have an AD 2003 Domain.
We have added the correct site and subnets to AD sites and services and the right DC is in the correct AD Site.
What we are finding is that this domain controller is not authenticating any clients in the applicable subnet ranges that it should be. There are no attempts for the clients to contact this domain controller, and they are being authenticated by other domain controllers and we dont know why.
We know that this domain controller is handling replication activities correctly such as user account creation etc, so we dont know why it is not authenticating clients.
We have run a dcdiag against this domain controller and all seems fine.
Any other help greatly appreciated.
