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.
