Exchange 2007 - transient failure has occurred

Hi Everyone,

Our Exchange 2007 Server has been running for almost 1 year without any problems, but recently Exchange stalls, and the server has to be restarted to resume the Exchange operations.

The following error messages appear in the event log:

The connection between the Client Access server and Mailbox server "heex.he.local" failed. If this event is logged infrequently or only during scheduled downtime for a Mailbox server, no user action is required. If this event occurs repeatedly, check network connectivity using PING or PingPath. Also, check connectivity using the Test-ActiveSyncConnectivity cmdlet. More information:
