What I want to be able to do is either:

1) Restrict access within IE by a username and password

2) keep track of website's viewed (people always go a delete the history and cache)

3) Or do a combination of the above.

It has to be able to work on both XP and Vista.

There will be approximatley 5-10 people using IE. And blocking website is not really an option as their are too many legit sites.

Any idea's on how I can go about this? The best solution would be free, and Linux is not really an option at this stage. Unless someone can devise a way to do it all on a flashdrive or bootable CD which requires not setting up each day.
