Terminal Services in Windows Server 2003 includes Remote Desktop for Administration, which allows administrators to remotely manage Windows 2003-based servers, and Windows 2000-based servers.
When you install Windows Server 2003, Remote Desktop for Administration is automatically installed, but it is disabled for security reasons by default.
NOTE: If you use Terminal Server mode, the server accepts more than two simultaneous connections by non-administrators, but you must install the Terminal Services Licensing service on a domain controller.
NOTE: In Windows 2000, the Remote Desktop Connection client is named Terminal Services client.
To enable Remote Desktop for Administration:
1. In Control Panel, open the System applet.
2. Select the Remote tab.
3. Check the Allow users to connect remotely to your computer box and press OK.
To change the encryption level:
1. Open Terminal Services Configuration from the Administrative Tools folder.
2. Select Connections in the left-hand pane.
3. In the right-hand pane, right-click RDP-tcp and press Properties.
