sampasswd [options] -uuser <samfile>
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.
Show summary of options.
Reset the user's password.
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.
Lists the users in the SAM database.
Output human readable output. The program by default will print a parsable table unless this option is used.
Do not allocate more information, only allow the editing of existing values with same size.
Do not expand the hive file (safe mode).
Print debug information of allocated blocks.
Print verbose information and debug messages.
- 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.
If the username includes international (non-ASCII) characters the program will not (usually) find it. Use the RID number instead.
