How to Break Domain Controller Password without Logging In

Forgot domain administrator password and couldn’t log on your domain controller? This is the most common password problems that many network administrators and system administrators face when dealing with domain controller. Here we’ll show you an easy way to break domain controller password quickly and easily.
Reset Windows Password is the powerful utility which enables you to break domain controller password on Windows Server 2008/2003/2000. This utility works offline, that means you need to shut down your computer and boot off your computer using a CD or USB stick.
How this software works?
Windows Active Directory stores the domain user passwords and other account information in a file called NTDS.dit. This file can be usually found in:\windows\ntds. This file is a part of Active Directory database and remains inaccessible as long as the domain controller is running. Hence, it is necessary that you boot off your computer and access this NTDS.dit file via the boot disk. This tool intelligently gains access to this file and will reset/change the password associated with administrator or any other domain user account.
