To enable a computer for Windows PowerShell remoting, you must configure the listeners to listen on the correct ports. For a single computer, you can use the Enable-PSRemoting cmdlet. To configure the listeners on all computers in a domain, enable the Allow automatic configuration of listeners Group Policy setting.
If you try to connect to a remote computer that is not enabled for remoting, Windows PowerShell displays one of the following errors, depending on the circumstances.
ERROR:ACCESS IS DENIED
- or -
ERROR: The connection to the remote host was refused. Verify that the WS-Management service is running on the remote host and configured to listen for requests on the correct port and HTTP URL.
