Multiple Sessions for one user

Parallels Remote Application Server (RAS)

Hi!

Is it possible to allow multiple Sessions for one user? He should be able to open the same application on different devices simultaneous.

This is the windows setting, use Local (gpoedit.msc) or domain (gpmc.msc) Group policy
Look for
Computer Configuration\Administrative Templates\Windows Components\Remote Desktop Services\Remote Desktop Session Host\Connections\Restrict Remote Desktop users to a single Remote Desktop Services session
and disable it. If you disable this policy setting, users are allowed to make unlimited simultaneous remote connections by using Remote Desktop Services.
Then refresh the policies by gpupdate /force or reboot the host.
