How to see what websites other computers are on?

Question

I am an IT Technician at a company and I have been assigned a job by my boss to find a program that can allow me to see what websites other people are viewing on our network. I once had a program that allowed me to see IP Addresses and what websites the IP Addresses (or computer names) is accessing, but I don't have it anymore. I am happy with just doing that, but also if we can see what IP addresses on our network is getting the most bandwidth and also what websites is getting the most bandwidth? Any applications will help. Thanks a million:-)

Answer 1

Try installing a Proxy server on your network.  Then require all users to go through this to reach the Internet.  You can then track either to the workstation or to the user (depending how you configure your proxy) what they are visiting.

** Edit **

In addition to monitoring sites visited, you can also add restrictions to block certain sites.  Subscribe to various list and setup rules to block content based on type (i.e. adult material, malware, games, web mail, etc...).  My company blocks all of these.  Schools will use it to block social networking sites like MySpace, FaceBook, and others.
