If you’re like me, you have many computers that you connect to remotely when away from work, or home, using RDP.

The easiest way to connect to all of these computers (aside from setting up a VPN) is to change the default port on which Windows will accept RDP connections.

Since things have changed a bit in Microsoft Windows Vista, here is how to change that port:
Click on the Start button, and navigate to accessories. From there, clik on the Run icon. Once the Run applet has started, we’ll enter the good ole regedit command. It still works like a charm!

Within the registry editor, navigate to:

Computer\HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\
Terminal Server\WinStations\EH-Tcp

We want to change the registry key PortNumber in order to modify the default port. The default port is 3390, and I normally use ports in the 338x range, so double click on the key, check the decimal setting, the set the “Value data” to 3389.

Click OK, then close Regedit, and connect from a remote PC.

Note: you may want to create a firewall rule for port 3389 in order to allow connections.
