I am not behind a xp machine so I can not go into detail with you.
What you have to do is to create 1 user (lets call it schooluser1) with the settings that yo want. So login as that user (schooluser1) and configure that user.
Next login as the administrator and go to the local users and groups snapin and create the other users (schooluser1, schooluser2, etc). 2x click on the other users (shooluser2)you create and select the profile path.
In here you have to provide the path of where the profile of schooluser1 is. (it would be c:\document and settings\schooluser1)
And that's it.
Hope this helps,
Leopold
