By default, Terminal Server (For Windows 2000 and Windows Server 2003) and Remote Desktop Protocol (for Windows XP and Windows Server 2003) listens on TCP port 3389.

1. Run Regedit and go to this key:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Contro l\Terminal Server\WinStations\RDP-Tcp

2. Find the "PortNumber" subkey and notice the value of 00000D3D, hex for (3389). Modify the port number and save the new value.

You can now connect to the new port by using the RDP client found in Windows XP, or even better, the newer Windows Server 2003 SP1 RDP 5.2 client (Download RDP 5.2).

Type the IP address then :portnumber (for example 192.168.1.1:3390)

You'll need to configure your TS client to connect to the new port. Although changing the connection port on the RDP clients is quite easy, you CAN also change the connection port for the TS client.

(This will also work for XP, but you're usually limited to 1 session, whether its local or remote)
