Event ID 333: An I/O operation initiated by the Registry failed unrecoverably

Last Updated: 7/11/11

Problem:
Event Type:    Error
Event Source:    Application Popup
Event Category:    None
Event ID:    333

Description:
An I/O operation initiated by the Registry failed unrecoverably. The Registry could not read in, or write out, or flush, one of the files that contain the system's image of the Registry.


Solution:
Update vendor software that uses low level drivers (backup software and antivirus software). We updated our Symantec Endpoint Security 11.0.4xxx to 11.0.5xxx, because 11.0.4xxx has a known bug with pool memory. Doing this resolved the error above on your server.
