Windows 2003 has a good feature is that you forget the password can be logged in Safe mode to find the password, in Safe mode with the administrator to login directly to enter the system without the need to enter the password, so you enter the operating system after the password reset can be.

But above this kind of operation need to operate in front of the server, need to go to the engine room, otherwise you can not enter the operating system Safe mode remotely.

Here we introduce the software brute force crack method


1. Download ERD Commander 2003 (Download address for www.fxxz.com/SoftDown.asp?) Id=3161&action=1). After the download is complete, change the extension of the "Winpe+erd2003.rar" file to ". ISO, and then burn the ISO image as a CD with a burner.

2. Use this CD to start the computer, enter the ERD Commander 2003 start interface. During the startup process, ERD 2003 may allow users to make some choices about the system hardware configuration. Because our purpose is only to use it to modify the password, so choose "yes" all the way.

3. Next, the ERD 2003 will search all installed systems on your hard drive, after which you can select the directory where you want to modify the login password, and then press [OK] to enter the ERD 2003 desktop.

4. The interface of the ERD 2003 is similar to Windows XP. Click the Start button on the taskbar to select the Administrative tools → password modification command, which pops up the ERD Commander 2003 Locksmith Wizard Welcome page. Click "Next" and a dialog box appears to modify the system login password. In the dialog box, select a username first, and then enter the password you want to set in the Password box below. When you are done, click [Next], and the system prompts "The password has been modified successfully, please restart the computer to test the new password". Click [Finish] and then press the prompts to restart the system, then use your modified password can login to the corresponding account.

Some other legends of the internet to crack the 2000/xp/2003 password is as follows:
1, delete sam file-This method is valid for Win2000, not only for XP and 2003, but also for system deadlock and completely unusable.
2, use WinPE to boot into the console, and then use the DOS command to manually add users--unless the original administrator password is not set, otherwise invalid.
3, the screen protection renamed, will cmd.exe renamed as LOGON.SCR (of course, to hang on other machines changed), after the boot wait 10 minutes into the screen protection, actually entered the DOS command line interface, can use NET command plus users-

-It has been proven that in SP1, SP2, 2003, the permissions that go into DOS are not administrators at all, and therefore cannot be added to the user.
4, the hard drive hangs to other machines, the test Sam file, uses the LC4 violence to decrypt--theoretically can, but if the password is more complicated, the decryption time will be BT long.
5, with the Windows key floppy boot system, you can directly modify the administrator password--but I do not find any of the software registration code or registration machine, that is not really use the software
