I need to find a way to blocked internet access on approximately 25 of the machines that only allow them to surf to designated sites. Some of the PCs need to have unlimited surfing access. Currently I am using the Firewall, Access Restrictions with IP but am not finding this very convenient.
Does anyone have any suggestions? If at all possible I would like to steer away from software on the individual PC due to resources it takes up and a bulk of my users use heavy CAD programs.
