Hello, First of all, I want to confirm you are using Per Device CAL When you use the Per Device model, a temporary license is issued the first time a device connects to the RD Session Host. After a user sign in to the session, the RDS server instructs the license server to mark the issued temporary RDS CAL token as being validated. (1) If you are not sure about whether you have your per device key validated, check your registry in one of your client (2) . If you have that registry , you may have received your license, it may be a display issue. RDS license issue usually happens when you pay little attention to your version. (Lincense Server > CAL > Session Host) (3) Find the official link below: (1). https://learn.microsoft.com/en-us/windows-server/remote/remote-desktop-services/rds-client-access-license Per Device CALs (2). https://learn.microsoft.com/en-us/troubleshoot/windows-server/remote/remove-terminal-server-licenses-from-rdp Clean RDP client's license cache (3). https://learn.microsoft.com/en-us/windows-server/remote/remote-desktop-services/rds-client-access-license RDS CAL version compatibility
