Must Be Granted Allow Logon To Computer Through Terminal Services

Logon to this computer you must be granted the allow logon through terminal services. I have setup a AD in my virtual box and install ts. i also have create a client pc in my virtual box. Whenever from my client pc I connect to the ts web access to get the apps from the server. I key in my id and password it will prompt me this message. But I have already assign the rights. I have already enable this option allow logon through terminal service, allow logon through terminal locally. I have added remote desktop user to permission to it. But it seems like it not working. How I can do it? Or is it the ts license without activating I cannot access?
