Over the weekend, someone broke in to our offices and made off with a laptop. We have about an 18-hour window when that might have happened. I was hoping there would be an easy way to see, in the server's Security log, a machine being either shut down or disconnected from the network. The machine was on and logged on, but locked, when we left. Is there a descriptor or something I could search for in the Detail field that would scream "here's when the burglars were here, check the video"?
