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.

NetAdmins versus SysAdmins: What’s the Difference?

In this type of environment, you’ll be a sysadmin, netadmin, and security administrator all rolled into one. As organizations grow and decentralize, the complexity and scale of the infrastructure lead to specialization of the administrative roles. It’s not uncommon to see four separate roles emerge: Systems administrator Network administrator Database administrator Security administrator Search for job descriptions for sysadmins and netadmins, and you’ll see quite a lot of overlap. Although it’s fair to say that there are skills and knowledge that are common to all IT roles, there are also real distinctions, especially as you get into more extensive infrastructures. Systems Administrator  Systems administrators typically deal with the computing resources in the infrastructure — servers and desktops, and the services and applications that run on them.
