NAME

       sampasswd - reset passwords of users in the SAM user database

SYNOPSIS

       sampasswd [options] -uuser <samfile>

DESCRIPTION

       This  manual  page  documents briefly the sampasswd command.  This manual page was written for the Debian
       distribution because the original program does not have a manual page.

       sampasswd is a non-interactive command line utility that can reset a user's password  and/or  the  user's
       account  bits from the SAM user database file of a Microsoft Windows system (Windows NT, 2000, XP, Vista,
       7, 8.1, etc.).  This file is usually located at \WINDOWS\system32\config\SAM on  the  file  system  of  a
       Microsoft Windows Operating System

       On success, the program does not output any informatin and the exit code is 0.

OPTIONS

       -h     Show summary of options.

       -r     Reset the user's password.

       -a     Reset all the users. If this option is used there is no need to specify the next option.

       -u <user>
              User  to  change. The user value can be provided as a username, or a RID number in hexadecimal (if
              the username is preceded with '0x'). Usernames including international  characters  will  probably
              not work.

       -l     Lists the users in the SAM database.

       -H     Output  human  readable  output.  The  program  by default will print a parsable table unless this
              option is used.

       -N     Do not allocate more information, only allow the editing of existing values with same size.

       -E     Do not expand the hive file (safe mode).

       -t     Print debug information of allocated blocks.

       -v     Print verbose information and debug messages.

EXAMPLES

       sampasswd -r -u theboss
              Reset the password of a user named 'theboss', if found.

       sampasswd -r -u 0x3ea
              Reset the password of the user with RID '0x3a'.

       samusrgrp -r -a
              Reset the password of all the users in the Administrator's group (0x220)

       samusrgrp -r -f
              Reset the password of the administrative users with the lowest RID number.  This does not  include
              the  built-in  administrator  (0x1f4)  unless  no  other  administrative  user can be found in the
              database file.

KNOWN BUGS

       If the username includes international (non-ASCII) characters the program will not (usually) find it. Use
       the RID number instead.
