Cracking User Passwords in Windows 2000

For years, Windows NT administrators have used L0phtCrack 2.5 to obtain users' passwords in their domain. But, if you’ve tried to use this tool on your Windows 2000 domain controller, you know that it doesn’t work. However, you can use L0phtCrack to crack the passwords for user accounts in your Win2K Active Directory (AD) domain.

Although you might be familiar with using L0phtCrack on NT, note that the process has changed in Win2K. Because passwords are the fundamental lock on your systems, it is a good practice, provided your management approves, to regularly assess the quality of your users’ passwords and provide feedback to users who select easy-to-guess passwords. Without such a program, it is a foregone conclusion that users will pick simple passwords such as repeating characters, simple words, and spouse names. Win2K provides the same minimum password length and password complexity rules as in NT. To view these settings, go to the Account Policies section of your Default Domain Policy Group Policy object in Active Directory Users and Computers.

Cracking Windows 2000 And XP Passwords With Only Physical Access

This article will cover how to crack Windows 2000/XP passwords with only physical access to the target box. I won't be covering into the internal structure of LM and NTLM hashes or what makes them so insecure, there are many other articles on the Internet that cover the basics of NT security so I would recommend that you Google for them. I will assume that the reader already knows the basics. There are a lot of articles floating around that tell interested parties how to use programs like PWdump to get NT password hashes. Using PWDump is what most folks recommend when Syskey is enabled on a system since the hashes in the SAM file are encrypted. The problem is PWdump only works if you can run it from an administrator level account, and if the reason an attacker is cracking the hashes in the first place is to get an administrator account then PWdump is of little use.           Another question I get is why crack the password at all since one can get access to the machine by just d
