Cracking passwords

What tools can I use to crack or replace the passwords on a Windows 2000 machine?

There are a number of tools ranging from freeware to commercial software.

  1. John the Ripper
  2. L0phtCrack
  3. Emergency Boot CD: This CD contains a number of utilities, including password recovery and cracking tools.
  4. Offline NT Password and Registry Editor
  5. Login Recovery
  6. Ultimate BootCD
  7. Knoppix

If you are starting to get the feel that Windows passwords aren't that secure, especially if one manages to get physical access to the box, you are correct.
