Fix - No Remote Desktop Licence Server available on RD Session Host server

A fully functional and activated Windows 2008/2008 R2/2012 Remote Desktop Session Host server displayed the following message

error no licence

This was a simple setup on one server with the: connection broker, Session Host and Licensing server with RDS/TS CAL’s installed.

Even though the licensing seems to be configured correctly, in server manager:
ServerManagerLicencingOK

Licensing diagnostics:
Licdiag

everywhere you look, everything seems to be OK. But the license manager shows something odd where No licenses are being used? 
This server was used since late 2012 Some interesting things could also be found in the event logs, the following events appear
NoLicensesUsed

EventID: 1130
Source: TerminalServices-RemoteConnectionManager

The Remote Desktop Session Host server does not have a Remote Desktop license server specified. To specify a license server for the Remote Desktop Session Host server, use the Remote Desktop Session Host Configuration tool.

The RD Licensing grace period has expired and the service has not registered with a license server with installed licenses. A RD Licensing server is required for continuous operation. A Remote Desktop Session Host server can operate without a license server for 120 days after initial start up.

Solution 

Delete the REG_BINARY in "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Terminal Server\RCM\GracePeriod"

Only leaving the default.
regkey

After a reboot the server should be working fine and get the licenses issued now and being getting used
Licencemanager

Although everything seemed to be ok and configured correctly with valid licenses, it seems that the setup was still in a 120 day grace period, even though it was correctly configured.

Note: you must take ownership and give admin users full control to be able to delete this key.
