I have some users in a remote office who end up with a lot of 'down time' on their hands. Their manager feels that they are wasting time on facebook, twitter, etc. At this point, rather than threatening their jobs, he wants me to block their access to the social websites.
The kicker, of course, is that he doesn't want to spend any money...
The site has one pc that is shared by three workers. They use a common logon. There is a dsl connection with a simple dsl router that doesn't support content filtering.
Their pc is running Windows XP Professional.
Does anyone have any thoughts on how I can achieve this without purchasing software or an appliance?
