Forgot Windows admin password. Knoppix solution?? User accounts have an interesting history in Windows. If you forget your password in Windows 9x, resetting it is as simple as deleting a. With Windows NT, , and XP, Microsoft has increased its user security by creating different user accounts on the same system and passwords that protect them. However, unlike in Windows 9x, if you forget your Administrator password, your only recourse is to purchase a tool to reset your Windows password or to reinstall Windows to create a new administrator account.
If you have a Knoppix disc, you can download and use the chntpw tool, which is a small program that lets you reset the local passwords on a Windows system, and return to your system. However, this gives you a floppy image and requires that you mount multiple loopback entries to extract the utility from the floppy image to use under Knoppix.
While you can simply create an ntpasswd boot floppy, this means yet another rescue disk to carry with you, and the beauty of Knoppix is that you have access to all of your recovery tools in a single disc. You could use the apt-get wrapper, which is included for Knoppix, to download chntpw. However, to be certain you retrieve the latest version of chntpw , you must run the apt-get update, which downloads about 10 times as much data per repository as the KB chntpw package.
It saves bandwidth and time to download the package directly. Download the. Instead, you must convert it to a tar file, and then extract out the chntpw utility. Open up a terminal, and run the following commands:. Change the. This command makes use of the alien utility, which has the ability to convert files between.
This conversion is necessary to extract only the chntpw executable file. To reset the password, you must have write permissions on the Windows partition. Replace hda1 with your Windows partition. Once the partition is mounted, you must locate the directory containing the SAM file. Once you have navigated to this directory on the command line, reset the Windows Administrator password by running:.
The default for this utility is to edit the Administrator password, so there is no need to specify an account. Now that you're in the proper directory you can change the administrator password using:. At the prompt that asks you if you wish to disable SYSKEY select no, at the prompt to enter a new password simply hit return to set a blank password this is the safest option.
Make sure to confirm the change and write the hive files when prompted. This will reset the administrator password to a blank password so you can reboot and log in as the administrator. Another option is to use Offline NT Password and Registry Editor which is another bootable linux distribution with all the tools you'll need to reset your passwords. This set of tools actually utilizes the same ntchpw program and other utilities as Knoppix-STD, but you may have more success with one tool or the other.
The nice thing about this utility is that it's pretty straightforward. You simply boot off the CD and answer the questions as they're asked, there isn't any extraneous utility or options on the disk. Assuming you actually have access to the machine through another legitimate account cracking the passwords for other system accounts becomes much easier. Of course, using one of the above methods you could reset or discover the password to a legitimate account, then use that information to log in and utilize these programs.
Using cracking tools from the machine itself presents some advantage, but also some challenge. Anti virus or other security protections loaded on the machine might thwart attempts to load such software or crack the password, and without access to the administrator account it might be impossible to disable these safeguards.
