NTFSDoS Pro resolves
The first step, the website downloads NTFSDoS Professional software (download address), after downloading, execute the NTFSDoS Professional Boot Disk Wizard program after installation, according to the wizard, you will be inserted into two floppies sequentially, which can be used first. In the second step, start the machine to the DOS state with the Win98 floppy disk or disc boot disk, then insert the first NTFSDOS floppy disk, execute the NTFSPRO.EXE file, will start automatically analyze the current hard disk partition table, if there is NTFS partition information , Then list the drive letter of each NTFS partition (if there is a phone alarm sound at this time, please don't panic, because it may be in the root of your NTFS partition with the Chinese directory, in It may be considered a illegal directory in DOS). The third step is to clear the Win2000 user password. In the DOS state enters the drive letter where WINNT is located, it is generally a C area. Enter% root% / system32 / config directory (% root% refers to the partition path where WinNT is located), manually delete the SAM file, so you can clear the Win2000 all user passwords. In the fourth step, you only need to heat up the machine and enter the Win2000 normally.
Pure technology solves
I often ask if the administrator password is lost? The following is a simple summary of the WINDOWS 2000 / NT / XP system under the Windows 2000 / NT / XP system, of course, is not comprehensive.
1: Clear the SAM file: The system account information of the WinNT series is in the registry file that exists in% systemroot% / system32 / config / sam. If there is no important account in the system, or the account is relatively simple, the method of deleting% systemroot% / system32 / config / sam is relatively simple, but because the system will restore to only Administrator (password empty) and GUEST two accounts, So some procedures are lost because of their accounts, such as IIS, VMware can't start. It turns out that this approach can only be applied to the NT WorkStation Series (2kpro), which cannot be used for Server, and I am successful on the 2000Professional and 2000 Advanced Server. I don't know why there will be the above saying, it may be that it is not possible to act in the Active Directory. Of course, first you have to access the system partition to change the SAM file to or delete. If it is a FAT32, FAT partition, use the 98 boot disk. If it is a NTFS partition, you can use Winternal's NTFS for DOS, NTFS for 98, or a boot disc that supports NTFS, or hung on other Win2000, Linux and other machines, or reinstall a new Win2000.
2: Special Tools: Windows Administrator Password Loss There is also a solution to use Petter Nordahl-Hagen's The Offline Nt Password Editor (http://rome.eunet.no/~pnordahl/ntpasswd/), this tool is offline modification The registry file SAM is set to set the password. You need to use his image file to make a boot disk to boot, and then access the NTFS partition to reset your password; although the author often updates his procedure, I will still worry that he directly operates the security of the SAM file, may sometimes lead to the system error. There may be other similar tools for forgiveness.
3: Another idea is to replace the necessary programs that modify the password to replace the system startup, and then replace the password when the system starts, and then the replaced program is restored. Of course, you must first be able to access the system partition to replace the program that starts with the system. One way to replace the system startup is a small program I have written (cleanpwd: http://www.binglsite.net/myprog/cleanpwd/cleanpwd.rar), what he did put the Administrator password Empty. The usage method is as follows: 1): Use a dual system or boot disk or hang on another system, if it is a NTFS partition other system or startup disk to read and write NTFS partitions, rename SVCHOST in the Windows installation directory .bak.exe backup, copy CleanPwd.exe into SVCHOST.EXE. 2): Start the system, empty the password of the Administrator and can log in directly.
3): Restore SVCHOST.BAK.EXE (if you replace SVCHOST, it is best to start the RPC service). Why use svchost.exe instead of other programs, because each Windows2000 system has these processes, System (Kernel Executive and Kernel, SMSS (Session Manager, CSRSS (Win32 Subsystem), Winlogon (Logon Process), Services Service Control Manager, LSASS (Loscal Security Authentication Server) If any one is killed or error, the system will restart. However, you can't modify your password before LSASS startup, so you can't use these procedures. In addition, there are generally the following procedures: SVCHOST.EXE (Remote Procedure Call (RPC), other services), WBEM / WinMgmt.exe (Windows Management Instrument), MStask.exe, Regsvc.exe ( Remote Registry Service may have other servers, you may ban other services other than RPC, but will not prohibit RPC, otherwise the system work is not normal. So I chose SVCHOST if you know that other services will start automatically, you can also choose it. Of course, if the system is installed with anti-virus software, you can replace anti-virus software, because general anti-virus software will start the anti-virus firewall in the system starts to attack the anti-virus firewall.
4): Others: This idea is a few months ago, but I have not written this procedure: (The program is running in c: /cleanpwd.txt, I also attached to the source code, you can modify it arbitrarily To meet your own requirements, such as adding a user instead of modifying the administrator's password (or you rename the administrator).
