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
       program 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. 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

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