Suche @TSSESSION(Kix) Variable unter VBS

Hallo !
Ich bräuchte eine Funktion o.ä. in VBS, die prüft, ob man sich gerade am Terminalserver anmeldet wie unter Kix @TSSESSION.
Gibt es soetwas?

Currently @TSSESSION returns a 1 if KiXtart is running in a Terminal Server Session.

I would like to suggest it be enhanced to provide the following.

    @TSSESSION
    1 = Terminal Session on Server in APPLICATION MODE
    2 = Terminal Session on Server in ADMINISTRATOR MODE
    3 = Terminal Session on Windows XP Pro
    4 = Terminal Session on Windows Vista
