Well, it really doesn’t matter, as there indeed are some ways to solve this problem.
Method1 (This is a risky operation) Delete SAM file to clear administrator account password
Under the directory of Winnt\System32\Config where Windows 2000 program files locate, there is the SAM file, which is the database file of Windows 2000 user account passwords.
When you are trying to log on Windows 2000, the system will check whether the password you entered is the same with the encrypted data in the SAM file. If the two are completely the same, you can enter the system smoothly; otherwise, you are not able to log on the system. So we can use this method to delete the SAM file to restore the administrator password.
After the SAM file is deleted, restart the computer. Now, the administrator’s account has no password. You can log on to the system with administrator account without entering password. After you have entered Windows 2000, reset your administrator account password will be OK. .
Method2 To find the password from the SAM file
Here is the tool needed: LC4. Run LC4, open and create a new task, and then click “IMPORT→Import from SAM File”. Open the to-be cracked SAM, at this time LC4 will automatically analyze the file, displaying the user names. Then click “Session>Begin Audit” to start the cracking. If the password is simple, you will get the result in a very short time. Yet, if the password is complicated, the time needed is a little bit longer. In this case, we need to use the following methods instead of this one.
Method3 Use a password reset disk to create a new password
Log on to Windows XP on condition of no use of “Welcome Screen”, press “Ctrl+Alt+Del”, there displays “Windows Security”, click “Change Password”, there displays “Change Password” window. Backup the current user passwords: click “Backup” on the bottom left to activate the “Forget Password” wizard, follow its instructions to create a password reset disk.
If you have entered a wrong password on the Windows XP login window, a "Login Failed" window will pop up. If you really can not remember what the password is, click "Reset" to start the “Password Reset” Wizard. Then you can reset the password with the created password reset disk and enter Windows XP.
Method4 Use software programs to reset password
If you are an alien to computer settings, or can’t figure out what I am saying above, then come to use software programs to solve the problem. You don’t have to go directories, no need to know what is SAM, etc. These little programs are easy-to-use, providing step-by-step instructions, making them closer to common users. Among the sea of such little programs, I’d like to recommend you these : Windows Password Reset 6.0 and windows password unlocker 4.0(http://www.passwordunlocker.com) They can automatically clear the administrator’s password. After you restart the computer, you can enter the system through administrator’s account. These two programs right now is the best tools to remove the password after my constant comparison of similar tools.
