Questions
1. Given the date and time of the last error message that Rebecca saw, look through Rebecca s System log and use the following table to list the error events by their source name, time, and error ID. List only error events that occurred within 5 minutes of 5:00 p.m Central Time, and sort the list from oldest to newest. If you are not in the Central Time (US & Canada) time zone, change your computer s time zone to (GMT-06:00) Central Time (US & Canada).

Summary
Services are programs or processes that start with Windows XP Professional and run in the background, providing necessary functions to other programs and operating system components. The Services console allows you to perform basic com-

mands on services such as stopping, starting, pausing, resuming, and restarting services. You can also use the Services console to configure options for services such as the startup type, the user account under which the service logs on, and recovery options. You can also use the System Configuration Utility to enable and disable services.
You use Event Viewer to view the contents of Windows XP Professional log files. By default, Windows keeps three log files: Application, which records events generated by programs; Security, which records audit events; and System, which records events generated by Windows services. You can use Scheduled Tasks to schedule programs and batch files to run once, at regular intervals, at specific times, or when certain operating system events occur. Windows XP Professional saves scheduled tasks in the Scheduled Tasks folder, which can be accessed through Performance and Maintenance in Control Panel. System Restore works by creating restore points that contain a snapshot of the Registry (which includes user account, application, and hardware configuration) and a copy of certain system files that Windows XP Professional requires for startup. System Restore creates restore points automatically when certain events occur, and you can also create restore points manually. Remote Desktop allows users that are members of the Administrators or Remote Users groups to remotely gain access to a computer running Windows XP Professional. Remote Assistance allows a user who needs help to invite an expert user to connect to the user s computer. After the connection is established, the expert user can take shared control of the user s desktop, chat with the user, and send and receive files.
