256986 Description of the Microsoft Windows Registry



SYMPTOMS
When you start your Windows NT-based computer, you may receive the following error message:

TRAP 0000000E ============ PAGE FAULT =============


 * at linear address 00000002

tr=0028 cr0=80000011 cr2=00000002 cr3=00300000

Note that the register values you receive may vary.



CAUSE
This issue may occur if one of the following conditions is true:
 * The System registry hive is damaged.
 * The Boot.ini file contains invalid characters or incorrect settings.



RESOLUTION
To resolve this issue, use one of the following methods.

Method 1
If your computer can boot off of a CD-ROM, start your computer with the Windows NT 4.0 CD-ROM, click Repair, and then click Inspect registry files. If you have an updated Emergency Repair Disk (ERD), choose the option to use the ERD for repairs. If you do not have an updated ERD, choose the If you do not have the Emergency Repair Disk, press ESC option, and then choose to repair the SYSTEM registry file.

Method 2
Replace the System hive in the Config folder with the SYSTEM._ hive from the Repair folder. If you are using NTFS, start your computer from a Windows 2000 CD-ROM or Startup disk into the Recovery Console, and then copy the System hive file (SYSTEM) from the %SYSTEMROOT%\Repair folder to the %SYSTEMROOT%\System32\Config folder. If you are using the FAT file system, use a Microsoft Windows 98 Startup disk to copy the System hive.

IMPORTANT: The %SYSTEMROOT%\Repair folder contains a compressed copy of the System hive in the SYSTEM._ file. Expand and then rename the file to SYSTEM prior to using it. Note that this System hive is only updated if RDISK is run and the Update repair information option is chosen. If this is the case, use &quot;Method 3&quot;.

Method 3
If the %SYSTEMROOT%\Repair\System._ file is old and RDISK has not been run to update repair information, copy the %SYSTEMROOT%\SYSTEM32\CONFIG\System.Alt file (to create a backup), and then rename this file to %SYSTEMROOT%\SYSTEM32\CONFIG\System.

Method 4
If the preceding methods do not resolve the issue, create a parallel installation of Windows NT 4.0, and then restore the System hive from a tape backup to the original %SYSTEMROOT%\System32\Config folder.



MORE INFORMATION
WARNING: If you use Registry Editor incorrectly, you may cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that you can solve problems that result from using Registry Editor incorrectly. Use Registry Editor at your own risk.

If one of the first three methods in the &quot;Resolution&quot; section of this article resolves the issue, you can verify if the original System hive is actually damaged. To do so, run Regedt32.exe, and try to open the original System hive by using the Load hive command on the Registry menu. If you receive a message that the file is not a valid registry file, this confirms that the System hive you replaced was damaged.
