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. . . .

I have been facing an odd problem for the past few days and also am unable find a soln. on a website. I have a folder on my Win2K domain say "abc" which had permissions for user say 'x'. Even the administrator did not have permissions to enter into the folder. Now one fine day due to some problem in the domain I had to reinstall Win2K and all nodes. Luckily the folder and my data was saved coz it was on my 'D drive'. Now this folder "abc" is no more accesscible, even after I have created the same user 'x' and given it the same rights as before. Please guide me as to how I could retrieve my data from this folder "abc".<br>

Thanks, Regards, Ajay<br>

I am the administrator of a small network. Previous admin of this network have left the company, no one is knowing the password of admin active directory. so is there any tool to recovery the password from workstation while logging other than admin<br>

RE: Ajay's comments...as the administrator of the domain you should be able to "take ownership" of the files/folders in question...

Ajay: you need to "Take Ownership" of the folder. Right-Click > Properties > Security

Click The "Advanced" Button
Click The "Owner" Tab
Select a user("Administrators" would be the best)
Check "Replace Owner On Subcontainers and objects"

Click OK/Apply

Problem Soved :)
