To cause a computer that is running Windows XP Professional or Windows Server 2003, but is not configured as a Terminal Services server, to advertise itself as a Terminal Services server:
1. Start Registry Editor (Regedit.exe).
2. Locate and then click the following registry key:
3. Change the value of the TSAdvertise DWORD value from 0 to 1.
4. Quit Registry Editor.
5. Restart the computer.
Note Windows Server 2003-based computers that are configured as Terminal Services servers, and Windows 2000 Server-based servers or Windows 2000 Advanced Server-based servers with Terminal Services installed in either Application Server mode or in Remote Administration mode already have the TSAdvertise registry value set to 1. Therefore, these servers advertise themselves as Terminal Services servers.
