Date Time Version Size File name -------------------------------------------------------- 02-May-2002 14:28 5.00.2195.5722 45,328 Eventlog.dllWith this fix installed, you can implement an automatic backup process (by using a registry key) when the current event log cannot be extended. You can add a registry key for each event log to increase the time before the event log becomes full, or before the computer hangs. Note that the size of the event logs is still limited by the available resources on the computer (such as virtual memory and free disk space).
To use the new automated backup behavior after you apply this hotfix, you must add registry keys such as the following keys:
Data value: Value not present or 0 (zero) equals "disabled." (This is the default.) Any non-zero value equals "enabled."
If you are using the "Shut down system immediately if unable to log security audits" (CrashOnAuditFail) policy and if you do not clear the security log after you set the Security registry value to 1, the computer still stops responding when an audit failure occurs.
Description of the AutoBackupLogFiles registry entryUsing this entry causes the Event Log service to automatically clear a full event log and to back up the log file. On computers with the "CrashOnAuditFail" policy turned on, the computer continues to log events (instead of hanging because of an audit failure) if the current log file can be backed up automatically. By default, event logs are stored in the %SystemRoot%\System32\Config folder. If you turn on this registry value, a full log file is automatically backed up in the %SystemRoot%\System32\Config folder, the log file is cleared, and event logging resumes.
If you turn on this registry value, you must make sure to move or delete the backup log files from the System volume. If you do not, the volume may become full. Microsoft recommends that you implement a manual or automated procedure to move or delete the backup log files to prevent the backup log files from consuming all of the space on the System volume. If you turn on this registry value, take immediate action if you receive a "Disk full" message.
When a log file is successfully backed up, event 524 is logged with a source of "eventlog" in the Security event log file. The event is similar to:
