I have set my DHCP server to automatically configure my clients. In my DHCP the 252 option looks like this for my isa server http://SENTINAL:80.dat. But if i deselect use a proxy server and select automatically detect settings then my clients cant get on the internet. I have the firewall client software installed in all clients machines and the white arrow is pointing up. Did i miss something with the DHCP 252 ?
