I have a w2k domain with checkpoint nokia firewall. The work day is from 9 - 5pm I want to prevent users from using the internet between the hours of 9 - 1pm and from lets say 2:15 to 5pm. Is there a way I can do that. The IP stack of the workstation si configure by the dhcp server. I do not want to change user ip to static and block the ip address from the firewall. I am wondering if there is another way using windows.
