I am also working in a school and I face the same problems not only the student.

I found your script work great but I have not yet implement on my system.
You have remind Cariley to force Logon to Domain and lock down msdos.sys, how can we do that, if the user click cancel at login screen (sure in Win9x), then they will still bypass the login script.

Thanks for your attention.
