Managing a Windows 2008 Server Core installation locally using command prompt
Another way to manage a Windows 2008 Server Core computer remotely is by using the Windows Remote Shell (WinRS). WinRS uses Windows Remote Management (WinRM), which is Microsoft’s implementation of the WS-Management protocol.
To configure the Windows Remote Shell to manage a Windows 2008 Server Core computer, run the command WinRM quickconfig at the command prompt. This command will create a WinRM listener on the Windows 2008 Server Core computer. Type yes to confirm the changes and to create WinRM listener.
  C:\>WinRM quickconfig
                    WinRM is not set up to allow remote access to this machine for management.
                    The following changes must be made:
Create a WinRM listener on HTTP://* to accept WS-Man requests to any IP on this
                    machine.
