Unattended installation

[imaimaibah]

My company where I currently work for bought passware to reset passwords.

I have been making unattended installation CD of XP to reset administrator password.

I don't want to use floppy because a lot of users don't have floppy drives.

We share them when we need. I want to make it work only with CD.

I have followed documents on the web sites but I can not make it yet.

I need your help.
