Windows 2000 Administrator Password Recovery Number
Windows 2000 is a very successful operating system of Microsoft, not only powerful, stable, its excellent performance even surpassing the last Windows XP, while Windows 2000 has also become the most popular Windows system after Windows 98. However, there is an unexpected event. Do you have encountered the problem of forgetting Windows 2000 login password, which is a very tricky thing, if it is a personal user, it doesn't matter, as long as the time is allowed to reinstall Windows 2000, choose to repair the installation, however for companies In this manner, this loss can be large, reinstalling WINDOWS 2000 for at least 40 minutes, and the loss cannot be estimated.
So there is a way to recover the administrator password for a quick and effective manner? The answer is of course affirmative. After unremitting efforts, the author found a lot of recovery methods online, they are: screen protection law, input method loophole, start script, software modification, etc., let's introduce:
http://anheng.com.cn/news/23/285.html
First, the input method drain method: "Input Law Vulnerability" is a widely circulated WINDOWS 2000 method, but it requires a high system requirement, requires the system for Windows 2000 Simplified Chinese version or installed SP1 version, and no installation In the case of the input method patch, it can be used after the SP2, SP3 or input method is installed. Ok, let's take a look at its specific steps: move the cursor to the username input box, press the Ctrl Shift key on the keyboard, and the input method status will appear in the default installation state. Move the mouse to the input method Status bar Click the right mouse button. Select Help in the dialog box, select the Operation Guide or input method. Several buttons will appear in the operation guide or input method in the input window, click the left mouse button. Options button, select the Internet option in the dialog that appears, right-click the option button will appear, select the jump URL, if it is in local, then enter C: /, then enter the control panel, the author is here Not much to say.
However, if it is remote login, it is also necessary to have "Remote Terminal Services" with the system. Use the above method to the jump URL, and then write "X: / Winnt / System32" in the URL and find NET in the folder. EXE, click the right mouse button to create a shortcut, right-click this shortcut, modify the command line:
1. Add "User Guest / Active: Yes", double-click to run; 2, add "User Guest Password", double-click Run;
You can use Guest to log in with Guest after you are running three steps.
Second, the screen protection method: This method is a vulnerability to the Windows 2000 screen saver. In general, there is no operation within 15 minutes within 15 minutes of the system login interface, the system will start the screen saver, this program is logon.scr under x: / winnt / system32, this logon.scr is an executable file, if the user can Try to modify this file to reach the purpose of the landing. The easiest way is to change the logon.scr and copy the Explorer.exe under x: / winnt to the x: / winnt / system32 directory, so waiting for 15 minutes after landing, it is not the screen saver. But the IE browser, the following is the same as the "Input Method Law". So how do we do what we do above? If it is a FAT32 partition, then you only need to start with the Windows 98 floppy disk or disc, you can perform the above operation; if it is NTFS, you have to trouble some, you can put this machine hard disk Hang up to another Windows 2000 computer, do the above operation. Third, the startup script: "Start Script Law" is to use the Windows 2000's footsteps to reach the landing purpose. Everyone knows that Windows 2000 computer start / shutdown scripts (startup / shutdown s cripts) This is a new feature of Windows 2000. The startup script is a batch file that invites the user to log in, its function is similar to the automatic in Windows 9x and DOS. Implement the batch file autoexec.bat; Similarly, the shutdown script is a batch file running before the computer is turned off. Since the script file is run before the Windows 2000 login mechanism, we can set the system by modifying scripts (for example, add administrators, modifying passwords, etc.), as for how to edit these files already have been introduced (FAT32 The partition is started with a Windows 98 boot disk, and the NTFA partition is started with another Windows 2000 computer). Let's take a step step by step:
Write a batch file that can restore administrator passwords, which is "Net User Administrator 12345" and saves this file in the fault system partition "x: / winnt / system32 / grouppolicy / machine / scripts / startup" Next; Next to write a start / shutdown script configuration file Scripts.ini, its contents are as follows: [startup] 0cmdline = admin.bat 0parameters = and save this file in "x: / winnt / system32 / grouppolicy / machine / scripts "Next; let the system start from the fault partition, this time you can use the username:" administrator ", password:" 12345 "to log in to the computer.

Fourth, Software Modification: In many ways to recover administrator passwords, the use of software repair methods is the highest success rate. Undoubtedly, Erd Commander 2002 is a very good one, this is a 150MB RAR compressed file, with instructions in the file. After downloading it to the hard disk, and burn it through Nero to CD-R, so you make a Erd Commander 2002 boot CD, you can use it you can make any user password modification and file reading for Windwos 2000. Write and copy, the function is quite powerful!
1. First put the engraved Erd Commander 2002 into the CD-ROM drive, let the system start from the CD-ROM; 2. Everything that happens will make us surprised, starting out of the startup interface of Windows XP after starting dozens!
3, then, Erd Commander 2002 will analyze the system, search all operating systems, partition formats, and more on the system.
4, then enter the system selection interface of Erd Commander 2002, where all systems searched, if not found, the user can manually specify the Windows 2000 directory, click OK to continue.
5, then we see the main interface of Erd Commander 2002, simply in the same way as Windows!
6, then select Start -> Administrative Tools ---> LockSmith to enter the administrator password to modify the interface, you can reset the password of the Administrator, then select Reboot to restart, you can use the new password after you can use the new password. Log in.
V. Delete SAM (Security Account Management Database) Method: When we want to end this article, we found a very easy recovery method, that is, delete SAM. To understand this method, we understand what is SAM, SAM, security account management database (Security Accounts Management Database), which is the core of the Win NT / 2000 operating system, where the group account control domain controlled by the local machine and the operating system is stored. User account information. The start of the SAM stores the description information and permission information of each group in the domain, and the next portion stores the description information of the domain user and the encrypted password data. Super User Administrator's password is stored after the last "Administrator" string in the SAM file. And very interesting, if the system can't find the SAM file, it will allow the username: "administrator", password to log in to the computer, based on this principle, we can reach the destination of the landing computer by deleting the SAM file, SAM Save under X: / Winnt / System32 / Config, and the method of deleting this file has a lot, the most thorough is to hang the fault system hard disk on another Windows 2000 system.
Let's introduce so much, choose that one? It is recommended that everyone will try the screen protection method, enter the method, and remove the SAM (Security Account Management Database) method. If you don't try to start the script, it is very convenient to use the software modification method, premise your network condition Good enough and have CD-R and recorders. If the above method still does not solve the problem, then you can only reinstall the system, and warn yourself until you don't forget the administrator password!
