WMI causes object access failure events when an SACL is applied to the HKEY_USERS registry subkey in Windows Server 2003 or in Windows XP with Service Pack 2

When a system access control list (SACL) is applied to the registry subkey on a computer that is running Microsoft Windows Server 2003 or Microsoft Windows XP with Service Pack 2, Windows Management Instrumentation (WMI) causes object access failure events. Specifically, you receive a failure audit for the LocalSystem account when the LocalSystem account tries to open the registry subkey for the MAX_ALLOWED property. The service tries to access this subkey through the Svchost.exe process that is running under the LocalSystem account.

Additionally, the following event is logged in the Security log:

Event Type: Failure Audit Event Source: Security Event Category: Object Access Event ID: 560 Description: Object Open: Object Server: Security Object Type: Key Object Name: \REGISTRY\USER\.DEFAULT Handle ID: - Operation ID: {0,141727} Process ID: 1352 Image File Name: C:\WINDOWS\system32\svchost.exe Primary User Name: COMPUTER$ Primary Domain: WORKGROUP Primary Logon ID: (0x0,0x3E7) Client User Name: COMPUTER$ Client Domain: WORKGROUP Client Logon ID: (0x0,0x3E7) Accesses: MAX_ALLOWED Privileges: - Restricted Sid Count: 0

This problem occurs because of a bug in the Wbemcore.dll file.
