HR request to examine the web history on a users machine, can anyone recomend a good history tool

I can't directly answer that question, but would like to toss something up for future needs. Even if you find the tool you're looking for, you are assuming that the user isn't savvy enough to just clear the history. What you really need, especially in a corporate environment, is a web filtering appliance, service or software. This does two things. First, it allows the company to limit where users can go so future needs for searching history can be lessened if not eliminated. Second, if you need to search history, you can do so from the filtering device or whatever and even if the user has cleared the history the answers are still there. Over the years I have tried a number of different approaches to this and finally settled on a filtering appliance from St. Bernard, now Edgewave called iPrism. It does a nice job of blocking out what needs to be blocked and even helps protect us from users going to sites that are known to be phisihing sites or malware sites and it allows me to search history when I need to do so.
