By Default when we install Remote Desktop Services Role in Windows Server then it provides unlimited User Connections for 120 Days (Grace Period) without any TS License Server.
If this Grace Period get expire then Users will unable to login and get below mentioned error:
So to Fix this issue we can regenerate Grace Period for Remote Desktop Services or you can also install RDS CAL .However I am sharing Step to regenerate Grace Period which is mentioned below:
· Open Run
· Type "Regedit" and click OK
· Go to Location:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Terminal Server\RCM\GracePeriod
· Right Click on GracePeriod and click Permissions
· Click Advanced
· Click change
· type username to whom you want to give ownership and click OK
· Click Apply and then OK
- Now Click Add
· Select Domain Admin or any user whom you have given ownership above and click OK
· Give Full Control to Selected User and click Apply and then OK
· Now click on GracePeriod and delete key from right pane as mentioned in below Snapshot:
· Click yes to delete Key and reboot Server
Important Information:-
Post Server reboot you will again have 120 days RDS evolution license and you can delete it if it gets expire again and Server can be used for any number of days by using this method without purchasing RDS Licenses from Microsoft.
However it would be better to use Microsoft RDS CAL for Production Infra. Please use this trick only for your home lab for testing purpose
