A. Terminal Services in Windows 2003 and Win2K Server has two modes: Remote Administration mode (known as Remote Desktop for Administration in Windows 2003) and Application mode (known as Terminal Server mode in Windows 2003). Although you can toggle between these modes, doing so will affect the installed applications and will probably cause currently installed programs to be reinstalled.
To determine the mode in which a server is currently running, perform these steps:
If the Licensing or Terminal Server Mode value is Remote Desktop for Administration or Remote Administration, you're limited to two connections (plus a local console in Windows 2003) when you're in Remote Administration mode. If the Licensing or Terminal Server Mode value is Application or Terminal Server, you're in Application mode and in that mode can have multiple concurrent connections, depending on the number of existing licenses.
