SYMPTOMS
The following audit record may be incorrectly logged in the local Security log in Microsoft Windows Server 2003 or in Microsoft Windows XP:
EventID 516
Internal resources allocated for the queuing of audit messages have been exhausted, leading to the loss of some audits.
Number of audit messages discarded: 1
This symptom may occur when the following conditions are true:
- The “Audit object Access” policy is enabled.
- An access attempt to a named pipe occurs. This named pipe has a system access control list (SACL) in its security descriptor.
- Windows makes an access control determination for this access attempt.
Instead of event ID 516, you expect the following “object open" audit record (event ID 560) to be logged. Event ID 560 indicates success or failure. Whether a success or a failure is logged depends on the outcome of the access control determination.
