This image creates a Linux boot disk that will allow any NT user/admin account password to be changed to whatever is entered.

Here is the link:

You may want to use winimage rather than rawrite.

This is not a hacker's forum !!

Password cracking will take 2-3 days for a 6-8 char password, exponentially longer for more.

Not worth it.

If you want to recover files, get hold of NTFSDOS from www.sysinternals.com

Or - install NT to another directory on the system, and bootup into that to recover your files.

Note: this is not for hacker purposes, only a way to get hold of a forgotten administrator password, or if a hacker has change it:

Download l0phtcrack from www.l0pht.com.
Download NTFSDOS from www.sysinternals.com.
Boot the NT-machine from a DOS/Win98-floppy/hd, run NTFSDOS.
Copy the file SAM from the directory C:\WINNT\system32\config.
Start L0phtcrack and open the SAM-database.
Start processing the passwords.
Wait..

As Tim says, it could take days to get the passwords. But it does'nt have to. It depends on how complicated and long the passwords are (dots, dashes, etc).

I have used this solution a couple of times when costomers had forgotten the administrator passwords or when someother before you have installed the NT-machine and not have documented passwords.

Regards.

You can get the files off the drive simply by putting the disk in another machine (as a slave) and boot off the original (where you know the admin password) and you can access the drive and copy off the files you need.

If you the want to blank the admin password, you can delete the sam file.

In my opinion the comments before me does not clearly explains the hole solution. I've tried to shortly explain a complete solution to divya_sg's question. Is there anything wrong in that?
Should we help each other solve problems and learn more together here at E-E? That was only my intention anyway..

But, as I am so kind, I withdraw my answer and hope that divya_sg solves his problem.

You can do it making a repair disk, make the boot disk and insert them, when the system ask for the type of installation (Upgrade, Installation or Repair) select repair and one moment you have to select the type of fix, from there you can shutdown the administrator's password

If you can't be bothered with all this, buy the package from www.lostpassword.com, which just goes in and changes the admin password to something you hopefully won't forget.
