SYMPTOMS
When you use a computer that is running Windows 2000, you may receive the following error message:

STOP 0x00000051

REGISTRY ERROR



CAUSE
This issue can occur if there is a registry or Configuration Manager problem with your computer. The error message that is mentioned in the &quot;Symptoms&quot; section of this article is a Windows 2000 Executive character-mode STOP error message. An input/output (I/O) error may have occurred while the registry was trying to read one of the registry files. This issue may be caused by hardware or file system problems.

You may also receive this error message if a refresh operation does not work, which occurs when your computer encounters resource limits.



MORE INFORMATION
To resolve this issue, use one or more of the following methods:  If you have a Emergency Repair Disk (ERD), it is recommended that you restore the registry to a known operating state.For additional information about Emergency Repair Disks, click the article number below to view the article in the Microsoft Knowledge Base:

 If this is the first time that you have started the computer after you install new hardware, remove the hardware and start your computer again. View the following Microsoft Web site to verify that the hardware and the drivers for the hardware are compatible with Windows 2000:

For information about the hardware, contact the manufacturer. If you are installing Windows 2000 for the first time, verify that you have all of the Windows 2000 requirements, including the amount of required random access memory (RAM) and hard disk space to load the operating system. If Windows 2000 is loaded and you have not installed new hardware, restart your computer with recovery options set to create a dump file. If you continue to receive the error message, select the Last Known Good option when you restart your computer. If there is no Last Known Good configuration option, use the ERD. If you do not have an ERD, contact your technical support group.For additional information about the Last Known Good configuration option and other Windows 2000 boot options, click the article number below to view the article in the Microsoft Knowledge Base:
