Exchange 2007 Hub Transport can not contact Active Directory
Posted on 2008-06-18
We recently built a lab to mock our production environment. For some reason, the Hub Transport server does not appear to be talking to Active Directory. If I send an email from the mailbox server, it just hangs in the Hub Transport Queue. Event Viewer shows....
Event ID: 1009
Computer: Hub Transport
The Microsoft Exchange Mail Submission service is currently unable to contact any Hub Transport servers in the local Active Directory site. The servers may be too busy to accept new connections at this time.
From the research I've done and the possible fixes I've ran across, I've already....
Verified the local disks are not low on storage.
Made sure no Firewall filtering is taking place for network data or blocking RPC.
Exchange is not in a perimeter network.
Rebooted the Domain Controller, Hub Transport and Mailbox servers.
Verified Microsoft Exchange AD Services and Transport Services are running.
Has anybody else ran across this problem?
