issues with my exchange on outgoing messages
Intermittently get the following message in event log
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.
changed the set-TransportServer Exch0 -MaxConcurrentMailboxSubmissions from 30 to 50
tried stopping and restarting services, on both domain and exchange server
End up having to reboot the domain controller, at which time messages are sent
