We currently have a company on Server 2008 R2 domain. They have requested to have 5-10 AD users to only have access to 5 websites in total. These 5-10 users have assigned computers, so if this can be accomplished easier through individual computer than individual AD user we can do that. The rest of the AD users need to have access to all websites. We use Open DNS as our content filtering now. How do we set this up to only apply to certain users, if all users have to point to the same primary DNS of the domain server?
