#RDS - Windows Server 2012 RDS, Remote session was disconnected

Error: The remote session was disconnected because there are no Remote Desktop License Servers available to provide a license. Please contact the server administrator.


1. Go to registry, navigate to HKLM\System\CurrentControlSet\Control\Terminal Server\RCM
2. Delete the GracePeriod folder. (if unable to delete, right click on the GracePeriod folder, click Permission. Assign Full Control)

3. Then restart the server.
4. To validate RD Licensing configuration completed. Go to Server Manager, select Remote Desktop Services, on the Overview, under the Deployment Overview, click Task, select Edit Deployment Properties.
5. Click on RD Licensing, make Remote Desktop Licensing mode selected.(Per Device\Per User)
