    Do you have a proxy server?

      as Dumber says, a proxy should to this fine. If you want to experiment with it you can try freeproxy (http://www.handcraftedsoftware.org/) to see if this is what you want.

        implementing proxy is a better solution.

        you could also add domains you want to block on your internal dns server HOSTS file.

        for eg.

        youtube.com 127.0.0.1

          Editing the DNS servers hosts file will not help -- it will need to be done on the client

          I believe one of the online "no IP" services -- may be no-ip.org - offers a fairly simplistic web filtering service by pointing your DNS server at their servers for name resolution

            Just an fyi. On cisco switches/routers you can also block websites using NBAR

              Completely agree a proxy is the way forward, or a 3rd party solution such as webroot or even some trend micro AV products include URL blocking, but as a really crude/basic method, if you have DNS running on your server, create a new forward lookup zone for the website (eg facebook.com) and create an A record with no data in it, but pointing to 127.0.0.1

              You can also then setup further A records in your new zone for 'www' for example, again pointing to 127.0.0.1
