We are going to start deploying Kiosks where I work. It is a pretty new
thing for me. The best I have come up with so far is the securews.inf
group policy template from Microsoft. Has anyone used this with
success? did you use ZEN to manage GP?

Here are our system requirements that I know of at this point.

Windows XP SP2
IE 6 SP1
SAV 9 (should update itself)
Windows updates (via patchlink if Netware 6.5 Distribution points ever
work or possibly via Automatic updates).

Other than that users of kiosks should have no access to anything that i
am aware of...
