Explanation:

To plan a monitoring solution for 200 Windows Server 2008 servers and ensure that an e-mail notification is sent to an administrator if an application error occurs on any of the servers by using the minimum amount of administrative effort, you need to create event subscriptions for each server on one server and attach tasks to the application error events.
Event Viewer enables you to view events on a single remote computer. However, troubleshooting an issue might require you to examine a set of events stored in multiple logs on multiple computers.
Windows Vista includes the ability to collect copies of events from multiple remote computers and store them locally. To specify which events to collect, you create an event subscription. Among other details, the subscription specifies exactly which events will be collected and in which log they will be stored locally. Once a subscription is active and events are being collected, you can view and manipulate these forwarded events as you would any other locally stored events.
