I'm looking for the cause of this error in my Security Event Log. The server is Windows 2008 R2 Standard running Microsoft Lync 2010 with the integrated SQL (formally known as MSDE, I don't recall what they call it today). This error seems to occur about every 20 minutes or when manually running GPUPDATE. When it occurs I always get 3 in a row (never any more or less).
An operation was attempted on a privileged object.Subject: Security ID: LOCAL SERVICE Account Name: LOCAL SERVICE Account Domain: NT AUTHORITY Logon ID: 0x3e5Object: Object Server: LSA Object Type: - Object Name: - Object Handle: 0x0Process Information: Process ID: 0x1e8 Process Name: C:\Windows\System32\lsass.exeRequested Operation: Desired Access: 16777216 Privileges: SeSecurityPrivilege
Take a look at this thread in TechNet for a related discussion which may point you in the right direction.
BTW "SQL Express" is the name you are looking for.
