When we log in the system, the system will automatically and Config of the SAM automatic proofreading, found all the passwords and user names and encrypted data in the SAM file found, you will be successful login; If the error can not log on. So,
la gear mens shoes, our first method produced: delete SAM file to recover the password.
If you do not control the system cards have been included in any account, and there are two operating systems, you can use another operating system can access the NTFS boot the computer, or it is not installed on both systems, but can use other tools to access to NTFS. Then delete the C: \ WINNT \ system32 \ config directory SAM file, restart. At this time, there is no administrator password for the Administrator account. Of course, remove the hard drive switch to delete the SAM file onto other machines are also considered a good idea.
Tip: WindowsNT/2000/XP in the security of user account management and use of the security account manager (Security AccountManager, SAM) of the mechanism, the security account manager on the account management is conducted through a secure identity,
la gear walking shoes, security , identity when creating the account created at the same time, once the account is deleted, the security identity also be deleted. Security identity is unique,
la gear shoes, even if the same user name each time to obtain the security identity is created is completely different. Therefore , once an account is deleted, its security ID no longer exists, that is, re-use the same user account name will also be given a different security identity, does not retain the original without permission.
Security Account Manager
specific performance is% SystemRoot% \ system32 \ config \ sam file. SAM file is WindowsNT/2000/XP the user account database, all the user's login name and password, the Ministry and other relevant information will be saved in this file.
Tip 2: Use Off1ine NT Password & Registry Editor. The software can make use of Linux boot disk, the boot disk can access the NTFS file system, so you can better support Windows2000/XP. The use of the floppy disk in a run in the Linux tools Ntpasswd can solve the problem. And you can read the registry and rewrite the account password. The approach is simple, just based on their step by step post-prompt to do it. In this, I suggest you use the fast mode so the user will be listed for which you choose to modify the user's password. Admin group of users selected by default, automatically find the name of the Administrator replace the user, is very convenient.
Tip 3: Use the Windows Key 5.0. The software included in the PasswareKit5.0, used to restore the system administrator's password, run after the 3 files generated: txtsetup.oem.winkey.sys and winkey.inf, 3 files total of only 50KB, short and pithy. Any of these three files on a floppy disk,
la gears sneakers, and then start the computer using the XP installation CD, press the F6 key during startup the system to install third-party drivers. At this point, what we cut the best time to release the floppy disk will automatically jump to WindowsKey interface. It will force the Administrator password changed to \
Tip 4: Use NTFS DOS this can be written under the NTFS partition from DOS tools. The software used to make a DOS boot disk, and then to C; \ Winnt \ System32 under the screen saver logon.scr renamed, then copied command.com to the C: \ Winnt \ system32 Next (2000 can be used cmd.exe), and rename the file logon.scr. So the bootstrap the machine, wait 5 minutes, this should appear in the screen saver now becomes a command line mode, but with Administrator privileges, it can be modified by adding a new administrator password or account of. Do not forget to change after the screen saver's name changed back ah. Download: http:/www.cgsecurity.org/index . html?
Tip 5: Here's a rather different approach. You can then install a different partition on the XP, hard drive partition format should be the same as the original, and certainly not to draw your attention to the original XP installed on the same partition! Before you begin, be sure to back up pre-boot MBR (Master Boot Record). There are many ways the backup MBR, you can own programming, or use software tools such as antivirus software KV3000. Bahrain with the Administrator login, and now you have the original XP write access to the absolute. You can copy down the original SAM, with lOphtcrack get the original password. Can also be the newly installed XP, Winnt \ System32 \ Config \ all the files under the cover C \ Winnt \ System32 \ Config directory (assuming the original XP installation here), and then restore the previous backup KV3000 master boot MBR Now you can use the Administrator login as the previous XP.
Tip: MBR commonly known as \ District 1 position, that is vulgar 0 track your location. It is produced by the partition fdisk command. Including the hard disk MBR partition table boot program and the two parts. MBR end marker for the 55AA, use the F6 function KV3000 anti-virus software to see, the default screen is the MBR. If the MBR can not find the active partition, it will display on the screen such as the Missing operating System error message,
la gear originals, so if you can not properly open the WindowsXP. And you see on the screen an error message like this,
la gear light, because many of them are out in here
