I am trying to login my user in server 2008 with domain controller as per this document. But the "Allow log on locally" in Group policy is not enabled. It is in hidden mode and one warning message is displayed near properties button saying that "If you modify this access, compatibility problem may occur for clients". But in all documents same procedure is mentioned. How can i enable that option? Remote desktop login is working fine and Administrator login too working. Please check the image below
Please note: I am domain admin and I have all rights in domain server to alter any settings.
Please anyone help how can I enable login to user in server
