i've look around and didn't find a solution for my problem so i decide to turn to the pros.
I have a customer who I just installed a server on server2012 DC configure. There is 4 clients computer on Windows 7 Pro. Everything work fine. Last week he called me and asked me if it was possible to block any browser on the computer and only allow it between 12:00 and 13:00 (lunch break).
Im pretty sure there's a way to do it and thats why am asking you help.
Thanks for your time and help!
