While Windows installed with Terminal Server role it does work without License for 120 Days on trail license, where within 120 days if the License server is not connected, the server will stop accepting connection with below error and event ID:

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 is 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. Obviously, use this solution only for test and not in production environment.

If you have a home lab environment or other lab that you continually test various solutions, licensing and trial expiration is a challenge that you constantly tend to run into. It is just part of the fun of lab environments. While most trials are fairly “hard and fast” and don’t allow you to reset the trial expiration, if you work with Microsoft Windows Server and Remote Desktop Services (RDS), there is a “hack” that allows you to effectively reset the expiration of Remote Desktop Services grace period where you can essentially rewind the clock on your RDS licensing if you are making use of this role inside your lab environment. In my lab environment, I am making use of Windows Server 2019 for my Windows workloads. In this post, I will show how to reset 120 day RDS Grace period on 2016 and 2019 Windows Server. Let’s see.

  Hi,
  
  First of all sorry if this is in the wrong forum - since it involves sysprep I thought it was most appropriate here. So basically, I cant work out how to get sysprep to reset the RDS grace period on Windows Server 2008 R2. I am using: sysprep /generalize /oobe /reboot /unattend:Unattend.xmlto sysprep the systemand it works like a charm.
  
  The only problem I have now is that it wont reset the Remote Desktop Service's grace period it will continue to count down from 120days since it was originally installed on the system. I have tried activating the licenseserver before running sysprep, and a few other hacky sort of things (ie: Delete %windir%\System32\LServer) without success. Thegrace period continues to countdown from 120 days from original install. Any help on this matter would be great =)
  
  Regards.

  sysprep to reset the RDS grace period? Are you correct? I have never heard about that.

  If you have installed an RDS Server 2016 for testing purposes and the RDS licensing grace period has expired, then continue reading below to learn how to reset the 120 days grace period.

  * Important: Apply the instructions below, only if you 're using the RDS Server 2016 on a testing environment. If you want the want to use the RDS Server on a production environment then proceed and buy RD CALs.
