Dear Sir,
Our Both Servers (NAV Server & SQL Server) are on Azure. The Client Service Port on NAV Server is 1234 & it's working fine till day before yesterday. Yesterday onward, it stops working. The following error message is found in Event Log while trying to start the service.
Server instance: DynamicsNAV90
The service MicrosoftDynamicsNavServer$DynamicsNAV90 failed to start. This could be caused by a configuration error. Detailed error information: System.ServiceModel.AddressAlreadyInUseException: There is already a listener on IP endpoint 0.0.0.0:1234. This could happen if there is another application already listening on this endpoint or if you have multiple service endpoints in your service host with the same IP endpoint but with incompatible binding configurations. ---> System.Net.Sockets.SocketException: Only one usage of each socket address (protocol/network address/port) is normally permitted

But the Status of the 1234 PORT is found free in netstat.
What is the issue ? How to resolve it ?
Kindly help.
