Symptoms

You have installed multiple instances of adTempus. When you try to start the adTempus service, it fails to start and adTempus reports the following error in the Application log in the Windows Event Viewer:

Failed to initialize listeners for remote connections: There is already a listener on IP endpoint 0.0.0.0:3760.  Make sure that you are not trying to use this endpoint multiple times in your application and that there are no other applications listening on this endpoint.: Only one usage of each socket address (protocol/network address/port) is normally permitted

Resolution

To run multiple instances, the Net.Tcp Port Sharing Service must be running on the computer. By default this service is disabled. You must change the startup type for the service to "Automatic" and then start it. After doing so, restart any instance of adTempus that was already running, and you should now be able to start additional instances.

See the Multiple Instances topic for more information.

Status

This behavior is by design.
