The Master Browser went offline and an election ran for a new one. In a nutshell, there is no way to reliably track user logoff events in the Windows environment.

You might want to see if you have any current sessons to your server before you try null session with " net use " command and delete them if there are Microsoft's comments: This event does not necessarily indicate the time that a user has stopped using a system.

A logoff audit is generated when a logon session is destroyed. So now I can indeed verify that I am able to establish a null session with my server; and 'yes' it apparently does log a 538 upon session termination. Is this correct? http://seforum.net/event-id/event-id-7036-not-showing-in-event-viewer.html It will use broadcasts only, if a wins server is not available.
Those often are null sessions used by the computer browser service. Windows Event Id 528 If not, you could have Conficker Worm..

The corresponding logon event (528) can be found by comparing the

A well-behaved application closes the handle to the token when it's finished with it, causing the reference count to be decremented.
