Follow these steps if you can't log into your PC and see a dialog box that says "To log on to this computer, you must be granted the Allow log on through the Terminal (or Remote Desktop) Services right...."
You're seeing this error message because the user you're trying to log in as does not have the correct permissions to use Remote Desktop. To fix this, we'll grant these permissions to your user account. Note: Please be careful when following these steps, make sure you follow these steps as listed here.
