Windows NT 4.0 is the successor to the Windows NT 3.x release. In this release, the user interface from Windows 95 was integrated, making NT just as easy to use as its consumer counterpart. Internet Explorer was bundled, providing a web browser out of the box. Speed was improved by moving components into kernel-mode, at the expense of security and reliability - changes Windows is suffering. We have a Windows NT 4.0 Workstation which we forgott the admin password. The admin is the only user assigned to the machine. I want to know, is there any free software out there that will let me reset or change the password of the administrator? Or how can I gain access to the Win. HashCat, an open-source password recovery tool, can now crack an eight-character Windows NTLM password hash in less than 2.5 hours. 'Current password cracking benchmarks show that the minimum eight character password, no matter how complex, can be cracked in less than 2.5 hours' using a hardware rig that utilizes eight Nvidia GTX 2080Ti GPUs, explained a hacker who goes by the.
Hash Suite by Alain Espinosa
Windows XP to 10 (32- and 64-bit), shareware, free or $39.95+
Hash Suite is a very efficient auditing tool for Windows password hashes(LM, NTLM, and Domain Cached Credentials also known as DCC and DCC2).It is very fast, yet it has modest memory requirements even when attacking amillion of hashes at once.The GUI is simple, yet uses modern features offered by Windows 7 and above.Besides the password security auditing program itself, there's an includedreports engine that generates reports in multiple formats, including PDF.(The reports engine requires free Java VM from Oracle to be installed.)
- Sep 07, 2004 Some of the Linux boot disk utility variants leave a footprint. The password is changed. Some include backup/restore features for the sam. With this feature, one could boot a Windows NT PC; backup the sam data; overwrite the pw; reboot; login using the compromised account and do mischief including sending inappropriate email or deleting bits and pieces here and there - darn those unreliable.
- In such cases 'Windows Password Kracker' can help in recovering the windows password using the simple dictionary crack method. Before that you need to dump the password hashes from live or remote Windows system using pwdump tool. Then feed the hash (LM/NTLM) for the corresponding user into 'Windows Password Kracker' to recover the password for.

This handy utility dumps the password database of an NT machine thatis held in the NT registry (underHKEY_LOCAL_MACHINESECURITYSAMDomainsAccountUsers) into a validsmbpasswd format file (which is understood by practically allWindows password security auditing tools).
This is the original pwdump program.It is mostly of historical value these days.You will likely want to use a newer reimplementation such aspwdump6 instead.You might also be interested in ourfile archive with local copies of many pwdump-like and pwdump-related programs.
Windows Nt Password Cracker
pwdump2 by Todd Sabin of Bindview
Windows NT/2000,free(GPL v2)
Download local copy of pwdump2 (46 KB)
This is an application which dumps the password hashes from NT's SAM database, whether or not SYSKEY is enabled on the system. NT Administrators can now enjoy the additional protection of SYSKEY, while still being able to check for weak users' passwords. The output follows the same format as the original pwdump (by Jeremy Allison) and can be used as input to password crackers. You need the SeDebugPrivilege for it to work. By default, only Administrators have this right, so this program does not compromise NT security.

Windows Nt 4 Iso
pwdump3 enhances the existing pwdump and pwdump2 programs developed by Jeremy Allison and Todd Sabin, respectively. pwdump3 works across the network and whether or not SYSKEY is enabled. Like the previous pwdump utilities, pwdump3 does not represent a new exploit since administrative privileges are still required on the remote system. One of the largest improvements with pwdump3 over pwdump2 is that it allows network administrators to retrieve hashes from a remote NT system.
pwdump3e provides enhanced protection of the password hash information by encrypting the data before it is passed across the network. It uses Diffie-Hellman key agreement to generate a shared key that is not passed across the network, and employs the Windows Crypto API to protect the hashes.

pwdump5 is an application that dumps password hashes from the SAM databaseeven if SYSKEY is enabled on the system.If SYSKEY is enabled, the program retrieves the 128-bit encryption key,which is used to encrypt/decrypt the password hashes.

pwdump6 is a significantly modified version of pwdump3e. This program is able to extract NTLM and LanMan hashes from a Windows target, regardless of whether SYSKEY is enabled. It is also capable of displaying password histories if they are available. Currently, data transfer between the client and target is NOT encrypted, so use this at your own risk if you feel eavesdropping may be a problem.
pwdump7by Andres Tarasco Acuna
Windows NT family (up through XP or Vista?), free
Download local copy of pwdump7 revision 7.1 (505 KB)
pwdump7 works with its own filesytem driver (from rkdetector.com technology) so users with administrative privileges are able to dump directly from disk both SYSTEM and SAM registry hives.Once dumped, the SYSKEY key will be retrieved from the SYSTEM hive and then used to decrypt both LanMan and NTLM hashes and dump them in pwdump like format.

Offline NT Password & Registry Editor by Petter Nordahl-Hagen
Windows NT to 8.1 (32- and 64-bit), freeware
This is an utility (available in the form of bootable floppy and CD images) to reset the password of any user that has a valid (local) account on your NT system, by modifying the password hash in the registry's SAM file.You do not need to know the old password to set a new one.
The editor works offline, that is, you have to shutdown your computer and boot off a floppy disk or a CD. The boot disks use Linux as the OS and include stuff to access NTFS partitions and scripts to glue the whole thing together.
This will also work with SYSKEY, including the option to turn it off.
