256986 Description of the Microsoft Windows Registry

SUMMARY

By default Terminal Server and Windows 2000 Terminal Services uses TCP port
3389 for client connections. Microsoft does not recommend that this value be
changed. However, if it becomes necessary to change this port, follow these
instructions.

MORE INFORMATION

WARNING: If you use Registry Editor incorrectly, you may
cause serious problems that may require you to reinstall your operating
system. Microsoft cannot guarantee that you can solve problems that result
from using Registry Editor incorrectly. Use Registry Editor at your own risk.



To change the default port for all new connections created on the Terminal
Server:

1. Run Regedt32 and go to this key:
   

   HKEY_LOCAL_MACHINESystemCurrentControlSetControlTerminal
   ServerWinStationsRDP-Tcp

   
   

   NOTE: The above registry key is one path; it has been
   wrapped for readability.
   
   
   
   



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.
   
   
   
   To change the port for a specific connection on the Terminal Server:
   
   
   
   • Run Regedt32 and go to this key:
     

     HKEY_LOCAL_MACHINESystemCurrentControlSetControlTerminal
     ServerWinStationsconnection

     
     

     NOTE: The above registry key is one path; it has been
     wrapped for readability.

   
   
   
   


3. Find the "PortNumber" subkey and notice the value of 00000D3D, hex for
   (3389). Modify the port number in Hex and save the new value.
   
   
   
   NOTE: Because the use of alternate ports has not been fully
   implemented for Terminal Server 4.0, support will be provided as "reasonable
   effort" only, and Microsoft may require you to set the port back to 3389, if
   any problems occur.

To Alter the Port on the Client Side

1. Open Client Connection Manager.


2. On the File menu, click New Connection,
   and then create the new connection. After running the wizard, you should
   have a new connection listed there.


3. Making sure that the new connection is highlighted, on the File
   menu, click Export. Save it as name.cns.


4. Edit the .cns file using Notepad changing "Server Port=3389" to "Server
   Port=xxxx" where xxxx is the new port that you
   specified on Terminal Server.


5. Now import the file back into Client Connection Manager. You may be
   prompted to overwrite the current one, if it has the same name. Go ahead and
   overwrite it. You now have a client that has the correct port settings to
   match your change Terminal Server settings.

NOTE: The Terminal Server ActiveX client listens on TCP
port 3389 and this cannot be changed. The Remote Desktop Protocol (RDP) client
that is available in Microsoft Windows XP and Windows .NET (version 5.1 and
later) has this ability.

NOTE: You must restart the Terminal Server before the new
listening port becomes active, or recreate the RDP listener via Terminal
Services configuration.
