How do I change the Terminal Server (or RDP) listening port?
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.
To change the default port for all new connections created on the Terminal Server:
1. Run Regedit and go to this key:
HKEY_LOCAL_MACHINESYSTEMCurrentControlSet ControlTerminal ServerWinStationsRDP-Tcp
2. Find the “PortNumber” subkey and notice the value of 00000D3D, hex for (3389). Modify the port number in Hex and save the new value.
You can now connect to the new port by using the “old” Windows 2000 Terminal Server client. A better option is to use the XP RDP 5.1 client (Download RDP 5.1). Even better, use the newer Windows Server 2003 RDP 5.2 client (Download RDP 5.2).
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. See Related Articles list for more info.
just add the new port in the connection string when connecting via RDP i.e.
Default port is 3389
