Event Log, Suspicious events?

[HelpWithEventLog]

Hi all,

I was looking through my event log this morning to figure out what time i got off the computer earlier in the morning (am) and found a whole lot of what looks to me as suspicious events in the security log.

I have uploaded an event log with the details to a couple hours.

Does anyone know what might cause all the logons and offs and account enumerations?

this is the url for the event file
