Dies habe ich getan, um den Desktop so zu sperren, dass nur Serveradministratoren und eine benannte AD-Gruppe darauf zugreifen können. Benutzer, die nicht Mitglied der angegebenen AD-Gruppe sind, erhalten eine Nachricht, in der sie aufgefordert werden, das RDWeb und nicht das Desktop- / Standard-mstsc zu verwenden.
- Erstellen Sie ein vbscript und legen Sie es in einem Ordner auf dem Server ab, den alle Benutzer lesen und ausführen können
Fügen Sie die folgende Zeile hinzu %windir%\system32\USRLOGON.CMD
cscript <sourcefolder>\DesktopUserCheck.vbs
