1. Find a file named SAM. The SAM file does not have an extension
2. Create a DOS boot disk
3. Boot into DOS and delete or renamed the SAM file
4. Boot back into NT and login as Administrator with no password.
This hack is great if you work on a locked down NT box and all you want is to listen to your damn MP3s!!! A couple of notes - this only works if you are using FAT16 or FAT32. Also I think it is better to rename files instead of deleting them because you can go back and fix any errors you have made and you can hide your not so 31337 hacking skills from IT. This only works locally. I have been told that this works in Windows 2000 as well but I have not tried it myself.
