Got an error appearing on a clients server, the error is as follows.
The Microsoft Exchange Replication service failed to start the TCP listener. Error: System.Net.Sockets.SocketException: An attempt was made to access a socket in a way forbidden by its access permissions at System.Net.Sockets.Socket.DoBind(EndPoint endPointSnapshot, SocketAddress socketAddress) at System.Net.Sockets.Socket.Bind(EndPoint localEP) at Microsoft.Exchange.Cluster.Replay.TcpListener.StartListening()
I have done basic troubleshooting such as restart server, the service etc. I have checked and the database is mounted and both copies are running. This does not seem to be impacting the users in any way.
As you can see, one of the common reasons people say is that there is something else on the ports that MSE runs on. However it seems that there is nothing else.
In the event log there is nothing but this error logged every 30 seconds, obviously making diagnostics difficult.
Any help or ideas would be amazing right now.
