SYMPTOMS

Consider the following scenario:
  • On a Windows Server 2003-based computer, you set the maximum size of the Security log to a large value. For example, you set the maximum size to a value that is larger than 60 megabytes (MB).
  • You select the Do not overwrite events (clear log manually) option in the Security log properties.
  • You configure the Security log to issue an event 523 when the size of the Security log reaches a warning level. To do this, you configure the WarningLevel registry entry under the following registry subkey:
    HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Eventlog\Security
    You set the warning level to a high percentage. For example, you set the WarningLevel registry entry to 80 or to 90.
However, when the actual size of the Security log reaches the specified percentage, event 523 is not issued to the Security log. Therefore, you are not warned of the Security log usage before the Security log is full. More security events cannot be issued when the Security log is full. In this case, some important audit events are not captured as expected.

Note A typical event 523 resembles the following event:

Event Type: Success Audit
Event Source: SECURITY
Event Category: System Event
Event ID: 523
Date: Date
Time: Time
User: N/A
Computer: Computer name
Description:
The security log is now WarningLevel percent full.

STATUS

Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section.

MORE INFORMATION

Windows Server 2003 and Windows 2000 Service Pack 3 include a new feature to generate a security audit event in the Security log when the log size reaches a user-defined threshold. For example, if the threshold value is set to 90, an event 523 will be issued when the Security log reaches 90 percent of capacity. This entry contains the following description:
The security event log is 90 percent full.
Note The threshold setting does not work if the Security log is configured to overwrite events as needed.
