An "event ID 516" audit record may be incorrectly logged when an access attempt to a named pipe occurs in Windows Server 2003 or in Windows XP (922769)



The information in this article applies to:

  • Microsoft Windows Server 2003, 64-Bit Enterprise Edition
  • Microsoft Windows Server 2003 R2 Enterprise x64 Edition
  • Microsoft Windows Server 2003 R2 Standard x64 Edition
  • Microsoft Windows Server 2003, Enterprise Edition for Itanium-based Systems
  • Microsoft Windows Server 2003, Enterprise x64 Edition
  • Microsoft Windows Server 2003, Standard x64 Edition
  • Microsoft Windows XP Professional 64-Bit Edition (Itanium)
  • Microsoft Windows XP Professional x64 Edition

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.
