You are a server support technician for a data warehouse company. Recently a Windows based server has had several unexpected shut downs. Where should you look first for more information?
On Windows based systems the Event Viewer will display a detailed log of events such as application crashes, power losses and other debugging information for the operating system, third party applications and hardware.

Event Viewer is a component of Microsoft's Windows NT operating system that lets administrators and users view the event logs on a local or remote machine. Applications and operating-system components can use this centralized log service to report events that have taken place, such as a failure to start a component or to complete an action. In Windows Vista, Microsoft overhauled the event system.Due to the Event Viewer's routine reporting of minor start-up and processing errors (which do not, in fact, harm or damage the computer), the software is frequently used by technical support scammers to trick the victim into thinking that their computer contains critical errors requiring immediate technical support. An example is the "Administrative Events" field under "Custom Views" which can have over a thousand errors or warnings logged over a month's time.
