Set Default Gateway for all users
I've recently taken down our schools proxy server. We had 2 gateways. One gateway was going into our proxy server, and out to the internet. The other gateway, was going into our firewall, and out to the internet. Strange setup, but that's how they had it. We have 2 IP's, one on the otherside of the firewall, and one on the otherside of our proxy server. The students went through the proxy, and the staff went through the main default gateway.
Here's the problem. I disabled the proxy service on the ISA 2000 server that always gave us troubles and never actually did a good job of blocking anything. I purchased a Barracuda Web Filter [the 310 model] and it's working flawlessly. The only issue is that the proxy server was now their friend, as students would try to access the internet through the proxy and have their sites they used to access back.
That's why I disabled the proxy service. So that gateway no longer goes anywhere. So the teachers are still being set at the main gateway through the ipconfig /setclassid * proxy command in their login batch file. However the student accounts dont have the permissions to write to the registry to make that entry. I'm not sure if this is something I need to set before hand on all the images under the network card and add it to the default gateways list, or if there's an easy fix like setting it at the domain level or having the dhcp server configure it automatically.
