Hello,The error occurs from a Windows 7 Home computer to a Windows 7 Professional computer.I connect successfully through a Sonic Wall VPN client.I can ping the IP address of the remote computer.

I run remote desktop (using IP address of the remote computer) and get error:"Remote desktop connection.  An internal error has occurred."

It used to work flawlessly and all of a sudden quit working.

Please advise.


  • Make sure your system firewall is not blocking the incoming/outgoing connection to Remote Desktop ports .
  • Make sure remote system's firewall is not blocking the incoming/outgoing connection to Remote Desktop ports .
        For eg: Windows firewall, Zone Alarm etc .
        Remote Desktop Port is 3389.
  • Check your network firewall configuration amnd kae sure it is forwarding remote desktop port 3389 ,if you are trying to connect to a remote system outside your network or through VPN .
