i want to limit rdp sessions per user to one on a Windows Server 2019 RDSH (vm). The vm is not part of a Remote Desktop Gateway Deployment, so it&amp;amp;#39;s a standalone session host.
I tried to realise that with a local GPO via
Computer Configuration &amp;amp;gt; Administrative Templates &amp;amp;gt; Windows Components &amp;amp;gt; Remote Desktop Services &amp;amp;gt; Remote Desktop Session Host &amp;amp;gt; Connection
and activated &amp;amp;#34;Restrict Remote Desktop Services user to a single Remote Desktop Services session&amp;amp;#34;
I also tried setting the related registry value Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Terminal Server\fSingleSessionPerUser to 1
However it&amp;amp;#39;s still possible for users to create multiple rdp sessions on that system.
I checked other RDP session hosts, that are behind a Remote Desktop Gateway. In such a setup somehow the limitation seems to be enabled automatically. So I compared the relevant registry values in Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Terminal Server of both machines. I could not find any differences related to my problem.
Does anyone has an idea what I am missing?
