Cannot start Publishing Tools service

I have ArcGIS Server 10.1 installed on Windows Server 2008 and am using the "one machine" approach where the ArcGIS Server and the web server are on the same machine.  I have the Web Adapter installed.  I cannot start the Publishing Tools geoprocessing service and get this error: "Failed to start the server machine xxxx.  Error while starting AppServer.  Required port '4,000' already in use.' 

My understanding from the install documentation ( is that ports 4000-4003 only need to be open if you have multiple machines as GIS servers.  Is this correct or do I need to open these ports to publish a map service using a one machine setup?
