Is there a way to make every user have the same profile? If I change one I want all the others to be the same.

We've got 3 Dell Latidude 2100 netbooks running Windows XP Home. At the moment I have to log on to every user on every 2100 to set up the Start Menu, Desktop(I'm using All Users) and the Proxy server settings for IE and proxycfg. Is there a faster or easier way to do all this?

I starting to think that we should just have 2 users, "teacher" and "child" rather than a logon for every year group(primary school.) The advantage of a log on for every user is direct access to our Windows 2003 R2 network with out the need to log on. It just connects. None of the users have passwords.
