On our network we use DHCP, but recently those IP addresses won’t browse to the Internet. We can get to everywhere on our internal network, but not to the Internet. We switch these people back to a static IP and it works. Then a few days later the static IP might not work, we go back to DHCP and it works again. We also have a PIX firewall in place. Can anyone offer an idea as to why this might be happening and a way to fix it?
