Reset Terminal license on Windows 2008, 2008 R2 and 2012


EventID: 1128
Source: TerminalServices-RemoteConnectionManager


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.



The official solution is to Activate the RDS/TS CAL License server and point the Server to License server with User/Device License and will be resolve the problem

But if you want to reset the timer and again avail 120 days grace time  here is the solution

The solution was to delete the REG_BINARY in
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Terminal Server\RCM\GracePeriod
Only leaving the default.


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

After a reboot the server should be working again for another 120 Days
