IMPORTANT: This article contains information about editing the registry.
Before you edit the registry, make sure you understand how to restore it if
a problem occurs. For information about how to do this, view the "Restoring
the Registry" Help topic in Regedit.exe or the "Restoring a Registry Key"
Help topic in Regedt32.exe.
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: Using Registry Editor incorrectly can cause serious problems that
may require you to reinstall your operating system. Microsoft cannot
guarantee that problems resulting from the incorrect use of Registry Editor
can be solved. Use Registry Editor at your own risk.
For information about how to edit the registry, view the "Changing Keys and
Values" Help topic in Registry Editor (Regedit.exe) or the "Add and Delete
Information in the Registry" and "Edit Registry Data" Help topics in
Regedt32.exe. Note that you should back up the registry before you edit it.
If you are running Windows NT or Windows 2000, you should also update your
Emergency Repair Disk (ERD).
To change the default port for all new connections created on the Terminal
Server:
Run Regedt32 and go to this key:
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\Terminal
Server\Wds\Repwd\Tds\Tcp
NOTE: The above registry key is one path; it has been wrapped for
readability.
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_MACHINE\System\CurrentControlSet\Control\Terminal
Server\WinStations\<connection>
NOTE: The above registry key is one path; it has been wrapped for
readability.
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
Open Client Connection Manager.
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.
Making sure that the new connection is highlighted, on the File menu, click
Export. Save it as name.cns.
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.
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 cannot
be changed.

Subject: Need to bypass Firewall-Can the telnet port be changed?
[7:12707]
I need to use the VPN to get to my study lab in the office. Unfortunately,
telnet appears to be blocked. Is it possible to change the terminal server
configuration so it answers on a different port such as port 80?
