SUMMARY
By default, Windows Terminal Server uses TCP port 3389 for client
connections. As a security option, you may want to change this port.
This article describes how to change the default listening port in the
Terminal Server Web Client.
MORE INFORMATION
To change the Terminal Server listening port in the Windows XP Service Pack
(SP) 1 (or later) and Windows Server 2003 clients, follow these steps:
- Locate the Default.htm file in the %system root%WebTsWeb folder.
- Open Default.htm in Notepad or in another text editor.
- Locate the entries that start with "MsRdpClient.AdvancedSettings2".
- Add the following line after these entries
MsRdpClient.AdvancedSettings2.RDPPort = xxxx
where xxxx is the new port.
To make sure that you can connect with the new setting, append the port
number to that of the published URL (that is, www.xxx.xxx.xxx:PortNumber).
NOTE: Before SP1 the Windows XP client used the Connect.asp
file, not Default.htm, for these settings. You can make the change described
in step 4 to Connect.asp, but Microsoft recommends that instead you upgrade
the Terminal Services Web client as described in the following Microsoft
