Blocking Web Browsing

How to prevent users from accessing the Web except for certain allowed sites.

A common request from admins is how they can limit users to being able to browse only certain websites and not others. One way of doing this is to configure your DNS severs so that they only resolve URLs you want users to be able to access. And in a Terminal Services environment you can also avoid putting DNS entries on the Terminal Server and instead use Hosts files that have pointers to the external DNS namespaces you want to allow access to. Finally, I'd be very interested to hear any other solutions readers might have for this scenario, please email me at info@mtit.com with your comments.
