Monitoring websites visited by users

I use websense for our company with about 400 users. It allows me to block the web altogether and also for just certain times and comes with a great reporting feature built in.

i run MS Small Business Server 2000 and handle around 50 users in one network. I can create a report through the Operating system itself. HOwever, if you have anything else then you got work around like if it is NT then check the user profiles see that it is on the server then you can monitor the user sites. But reporting you can do it from NT.

You need to implement some sort of Proxy server, that will log all internet activity. Microsoft ISA server in cache mode would suffice, or perhaps a linux/squid solution if cost is an issue. Once set up you need a software package that will analyze the generated reports. I use an inexpensive program called proxy log analyzer
