Can anybody help? I want to set-up a computer that sits in the exhibition centre at work for members of the public. It's currently off the network and just runs Windows XP with auto-login, some videos on the desktop and an internet connection to browse a few permitted web sites in Internet Explorer. Soon we're going to connect it to our network so I want to make sure it's locked down!

Ideally I'd like it to run Kubuntu Linux with Kiosk, it would both be easier for me, better (of course) and a nice way to demonstrate a computer running nothing but free software to my colleagues. But I also need to look into the possibilities with Windows (sigh) since we don't have anyone else in our charity or support company who knows anything about Linux.

Can anyone drop a comment with some tips for setting up a well secured video & web browser Linux box, and any hints for Windows?
