Interactive logon: Require Domain Controller authentication to unlock

Hello sir,

i am facing this problem in windows server 2008 r2, not any account can login to server through remotely or locally what can i do?...

"To log on to this remote computer, you must be granted the Allow log on through
Terminal Services right. By default, members of the Remote Desktop Users group have this
right. If you are not a member of the Remote Desktop Users group or another group that
has this right, or if the Remote Desktop User group does not have this right, you must be
granted this right manually."

Thanks

Regards

Sandeep
