Contoh Soal jadi Hacker
Yang kita butuhkan adalah sebuah Bootdisk image yang dapat didownload di http://home.eunet.no/~pnordahl/ntpasswd/bd040116.zip. Setelah didownload segera ekstrak dan jalankan file install.bat, tapi sebelumnya masukkan sebuah disket kosong ke dalam floppy disk drive anda. Ketika file install.bat dijalankan, maka sebuah floppy disk yang bootable akan dibuat. Nah, disket inilah yang akan kita gunakan untuk melakukan hack.
Setelah bootdisk selesai dibuat, restart komputer anda dengan membiarkan disket tadi tetap di floppy disk drive. Mungkin anda perlu mengatur boot sequence agar ketika booting yang pertama kali diboot adalah floppy disk drive.
Bila disket anda berhasil diboot, maka tinggal ikuti petunjuk saja. Berikut adalah cuplikan dari program tersebut : ( komentar saya akan diawali dengan tanda ‘–>’)

* This utility will enable you to change the password of almost
* any user (incl. administrator) on an Windows NT/2k/XP installation
* WITHOUT knowing the old password.
*
* The program is now able to actually parse/follow the internal
* registry structure completely.
* There is now support for adding and deleting keys and values.
* Tested on: NT3.51 & NT4: Workstation, Server, PDC.
* Win2k Prof & Server to SP3. Cannot change AD.

* or you may do it manually from the shell prompts.
*
* Good luck!

Calling scsi.rc to probe for SCSI controllers
Mounting floppy to fetch drivers from /scsi on it
SCSI-drivers found on floppy:
BusLogic.o.gz aic7xxx.o.gz
Do you have your NT disks on a SCSI controller?
y – this will autoprobe for the driver
n – no, skip SCSI, I have IDE drives
or give the scsi-driver modules name (without the .o or .gz)
+ optional parameters to go directly for a known driver
Probe for SCSI-drivers: [n]

Blanking password. This may actually fix things if previous password-preset
did not work. Or it may even make things worse. Happy joy!
