I am having trouble setting up Remote Desktop for our Windows 2008r2 server that is also a domain controller. I can login to the system as an administrator but a normal domain user gets the error "The connection was denied because the user account is not authorized for the remote login." I have looked into every policy and setting I could find to make sure the user has rights to connect.
The "Allow log on through Remote Desktop Services" is enabled and the group the user is in has been added/
The "Allow users to connect remotely using Remote Desktop Services" is enabled.
Remote desktop role and licensing services are installed on the server. (I do not have the cals installed yet but I am still under the grace period, and wouldn't I get a different error if that was an issue?)
I do not see any event error logs.
