I have a question about MS Proxy server 2.0. I have been tasked with tracking one of our user's web access. He is suspected of going to questionable websites and I have to extract from the logs where he went and when. I was able to do that, but the boss wants to know how long he was at each of the sites. Ok, so on to the point. Is there any way of determining from the W3*.log files created by MS Proxy Server 2.0 how long a user was at a particular site or if there are any programs out there that can do the same. I have searched Google and various other search engines for programs of this sort or articles written on this subject, but I haven't found exactly what I need. If anyone can point me in the right direction I would be deeply appreciative. Thanks in advance.
