CHNTPW(8)						      System Manager's Manual							 CHNTPW(8)

NAME

       chntpw - utility to overwrite Windows NT/2000 SAM passwords

SYNOPSIS

       chntpw [options] <samfile> [systemfile] [securityfile] [otherreghive] [...]

DESCRIPTION

       This  manual page documents briefly the chntpw command.	This manual page was written for the Debian distribution because the original pro-
       gram does not have a manual page.

       chntpw is a utility to view some information and change user passwords in a Windows NT/2000 SAM userdatabase file, usually located at WIN-
       DOWSsystem32configSAM  on the Windows file system. It is not necessary to know the old passwords to reset them.  In addition it contains
       a simple registry editor (same size data writes) and hex-editor with which the information contained in a registry file can be browsed  and
       modified.

OPTIONS

       -h     Show summary of options.

       -u username
	      Username to change. Default is Administrator

       -l     List all users in the SAM database.

       -i     Interactive: list all users (as per -l) and then ask for the user to change.

       -e     Registry editor with limited capabilities.

       -d     Use buffer debugger.

       -t     Show hexdumps of structs/segments (deprecated debug function).

EXAMPLES

       ntfs-3g /dev/sda1 /media/win ; cd /media/win/WINDOWS/system32/config/
	      Mount the Windows file system and enters the directory WINDOWSsystem32config where Windows stores the SAM database.

       chntpw SAM system
	      Opens  registry  hives  SAM  and system and change administrator account. This will work even if the name has been changed or it has
	      been localized (since different language versions of NT use different administrator names).

       chntpw -l SAM
	      Lists the users defined in the SAM registry file.

       chntpw -u jabbathehutt SAM
	      Prompts for password for jabbathehutt and changes it in the SAM registry file, if found (otherwise do nothing).

SEE ALSO

       If you are looking for an automated procedure for password recovery, you might look at the bootdisks provided by  the  upstream	author	at
       http://pogostick.net/~pnh/ntpasswd/
       There is more information on how this program works available at /usr/share/doc/chntpw registry works.
