Last night my Windows Server 2008 had an unexpected power failure. It has redundant power supplies and plugs into two different UPSed power sources. So how did it restart all on its own? When I logged in (it was on) it said the last time this machine was shut down unexpectedly and asked why. How can I trouble shoot this?
