Question : you do not have access to logon to this session

I've setup a DC with GPO's that restrict some user on the network. I'm logon to the DC as administrator. I want to RDP to the all the workstations in the network. It all work fine when I'm RDP from the DC to Domain Admin user. My problem is when I try to RDP to a client using a Domain User login it show a error massage  : "you do not have access to logon to this session."
Please help.

Answer : you do not have access to logon to this session

You'll need to allow some time for the computer accounts to take in the new group policy settings.  Do you have more than one DC in your AD environment?  If so, please wait ~20 minutes, then go to a workstation, open a command prompt and type:  gpupdate /force  Type yes to restart the computer, then test and see if it's working.
