    Based on the event entry, it looks like you have a program/process running
    under the network service account (or local system) and is attempting to
    logon using the advapi.dll LogonUser call.

    I know it's been a while since you posted this, but hopefully you resolved
    it. Just in case, I thought I'd point this out. I've been working on an
    ASP.Net application that uses the DLL for user login via a web application.
    Generally, you would want this web application running as a specific account
    - not the local system or network service accounts. That way you can more
    succinctly identify entries like the one you've posted.
