You will always be able to launch a full remote desktop as an administrator by pressing ctrl + alt + end,
which will display the task manager, allowing you to launch explorer.exe.
You will find below all of the reason why your users shows a published application instead of a full remote desktop:
- First of all make sure you are not attempting to log in with a remote app connection client, which cannot display a full remote desktop.
- The next move is to check your assigned applications, make sure that your groups and users have the "Remote desktop" application assigned, if that is the case this application will always have priority over others.
- The last step if none of the above has solved your issue is to manually edit with notepad the AppControl.ini file located in C:\Program Files (x86)\TSplus\UserDesktop\files
In the paragraph "Security", make sure that alwaydesktop=no (use this setting in last resort to force the use of the remote desktop)
You will also be able to check your application assigning settings here, in the example below only the local administrator has access to Microsoft Remote Desktop :
appname=Microsoft Remote Desktop
