Changing the default MS-Windows Terminal Service 2003 port

May i have to change the default port (3389) of the windows terminal service 2003 into server and into RDP client application to connect onto other port number (3390).
Because i have a NAT router which tansefer the inbound connections to terminal server1 also i have anther terminal server2 and i need to NAT inbound connections to it through the same NAT router like this:

public IP= 82.23.37.11 on port 3389 NAT to private IP= 192.168.4.20 on port 3389    terminal server1
public IP= 82.23.37.11 on port 3390 NAT to private IP= 192.168.4.21 on port 3390    terminal server2

Start Registry Editor.
2. Locate and then click the following registry subkey:
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\TerminalServer\WinStations\RDP-Tcp\PortNumber
3. On the Edit menu, click Modify, and then click Decimal.
4. Type the new port number, and then click OK.  
5. Quit Registry Editor.

Good Limjianan:
But this is for changing RDP port into client side application.
How can i change the terminal service port also into server 2003 to connect to.

what you are saying doesnt make a lot of sence, but that may be your english.
what you have been told will change the port that the server listens on for RDP/terminal server connections from the clients.
The clients will need to connect by typeing in :3390 (for term server 2) after their normal connection string.
eg.
Start MSTSC
type 82.23.37.11:3390
Click connect.
this will connect them to the second terminal server through port 3390

and of course, for internal user, they will have to connect via 192.168.4.21 on port 3390  

means mstsc -v 192.168.4.21:3390

hope it helps
