Overview of "Accident Recovery"
Computer failure is any event that caused a computer that cannot start or continue to run. The reason for the computer's failure is small to a hardware corruption, which is large to the entire system (for example, fire or similar events). Windows 2000 reports a "stop" error message when you encounter such an event, and display some necessary information, you and the Microsoft Product Support Service Engineer can use this information to determine and identify the problem.
Fault recovery is to recover your computer after a failure, enabling you to log in and access system resources. Windows 2000 provides the following options to help you identify your computer failure and recovery:
Security mode
You can start the system using the security mode launch option to start the minimum necessary service in this mode. The security mode option includes the last correct configuration, and if the new installed device driver occurs when the system is started, this option is especially useful.
Fault recovery console
If the security mode does not work, you can consider using the fault recovery console option. It is recommended that only advanced users and administrators use this option. Use the installation disc or the floppy disk created from the CD to start the system. The "Fault Recovery Console" can then be accessed, which is a command line interface that can perform tasks such as starting or stopping services, accessing local drives (including drives to NTFS file systems).
Emergency repair disk
If the security mode and fault recovery console does not work, and the appropriate advanced preparation has been made in advance, you can fix the system with an emergency repair disk. Emergency repair disks can help repair kernel system files.
Restore console
If security mode does not work, you can use the Recovery Console "; however, it is recommended when you are an advanced user or administrator (you can use the basic command ID and positioning the problematic driver and file) You use this method. The Recovery Console is a command line console that can be used after booting a launching disc in a computer CD drive or starting a computer using a floppy disk created.
To use the Recovery Console, you need to log in with the Administrator account. The console provides commands that can be used to perform simple operations (eg, to different directories or view directory) and more powerful operational commands (such as repair start sectors). You can get help information for these commands by typing HELP by typing Help at the "Recovery Console" command prompt.
Using the Recovery Console, you can start and stop the service, read, write data, write data, copy data, copy data, copy data from the floppy disk or CD using the NTFS file system system, and fix the start sector or main boot record. And perform other management tasks. If you need to repair the system from the floppy disk or CD-ROM, or if you need to reconfigure the computer that is not working properly, the Recovery Console is particularly useful. For example, you can use the "Recovery Console" with the correct copy of the floppy disk to replace the covered or damaged driver file.
Point
Because the "recovery console" function is very powerful, only high-level users or administrators are recommended.
Fix startup failure
If the disk system or startup volume fails, the system will not be able to start. The process from starting fault recovery depends on the configuration of the disk and the type of computer system microprocessor.
For systems or boot rolls configured as a portion of the mirror volume (can be applied to the unique fault tolerance method in the start and system volumes), the faulty recovery may use the boot disk.
Startup Disk
After creating a boot disk, you should test it before any faults, otherwise, if the primary disk is lost, you cannot start your computer from the mirror volume. Check the boot disk by starting the system from the mirror volume by using the boot disk. First open the master disk power supply and turn off the power to test your disk. In both cases, if you can log in, then the startup disk takes effect.
The boot disk should be upgraded each time you change the volume. For example, if you are using a volume 2 boot system, and delete volume 1, you must change the ARC name to enable Volume 1. Similarly, if the system is started on the volume 2, the volume 1 is deleted, it is divided into volume 1 and volume 2, and the ARC name must be changed to enable the volume 3. Maintenance start configuration
After the Windows starts success, back up the configuration directory (/ systemroot / system32 / config, and keep the current backup when changing the configuration and account. The registry consists of the files in the configuration directory.
If you must use the repair process in the Windows installer to restore the registry file, you can restore the configuration from the backup.
Don't delete boot.ini, ntldr, bootsect.dos, ntdtect.com or ntbootd.sys in the root of the system volume (if Windows is installed on the SCSI disk).
If you change the success of Windows successfully, but now there is a failed system, you can return to the previous configuration by selecting the "last correct configuration" in the system startup. If Windows still cannot start, start the system in the Windows installer. After the system is restarted, you can use backup magnetic to restore data.
Fix config.nt and autoexec.nt
If Windows displays an error message about these files, or when running a MS-DOS program, check if the config.nt or autoexec.nt file is not correct or lost. These files are located in the / systemroot / system32 directory.
If these files are not correct or lost, you can copy the new version of the file to the / system32 directory from the boot disk.
