I have a company that is using OpenDNS to filter ceartain web sites. The way I beleive it works is you set the workstations to use a OpenDNS servers. If you no longer wish for them to use OpenDNS filtering, then you use a different DNS server, such as 18.104.22.168.
Our domain controller has forwarders setup with only OpenDNS servers. So if I set a computer's primary dns server to 22.214.171.124 with no secondary server, then OpenDNS does not effect this computer. If i set the primary dns server to 126.96.36.199, and the secondary dns server to 192.168.1.200 (our DC, this way all internet traffic will use the primary dns server, and local stuff will fall back to the secondary dns server), then OpenDNS blocks stuff. This means that it's not using the primary dns server. Does anybody know why this is?
