Licensing grace period

When playing around with RDS in your LAB, you might run in to the problem that you have exceeded your grace period.

The RDS server will show the message: Remote desktop licensing mode is not configured. Remote desktop Services will stop working because this computer is past its licensing grace period. On the RD connection Broker server, use Server Manager to specify the Remote Desktop licensing mode and the license server.

If you try to connect from a client you will se this message: The remote session was disconnected because there are no Remote Desktop License Servers available to provide a license. Please contact the server administrator.

Given that this is just for testing and not production, you might not be able to specify a valid license server.

Open registry editor and go to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Terminal Server\RCM\GracePeriod right click on the key and select Permissions

After a server restart you will get a new full grace period: Remote Desktop Services will stop working in 119 days. On the RD connection Broker server, use Server Manager to specify the Remote Desktop licensing mode and the license server.
