Creating a DNS Stub Zone in Windows Server 2003/2008/2012

This guide will give you a walk through how to configure your existing Squid proxy server to provide content filtering capabilities for your Active Directory users.

This guide has been produced using Red Hat Enterprise Linux 6.3 and a Microsoft 2008r2 Active Directory domain.

If you currently do not have an existing Squid installation, you can follow my previous article on how to configure Squid for Active Directory authentication.

To start with, if you have read this far, you most likely already have an existing Squid installation on a server that has system authentication back to Active Directory. Follow the below steps to add Content Filtering with SquidGuard.
