Logon attempt by: MICROSOFT_AUTHENTICATION_PACKAGE_V1_0 Logon account: administrator Source Workstation: LOCALCOMPUTERNAME Error Code: 0xC0000064Data formatted as » None
Somebody has tried logging on using the local administrator account, but - the error code C0000064 tells us that there is no such user. You've probably got a slightly dippy admin who has forgotten that your local admin accounts are renamed as a matter of course.
