Types of events

Event Viewer displays five types of events:

Event type	Description
Error	A significant problem, such as loss of data or loss of functionality. For example, if a service fails to load during startup, an Error will be logged.
Warning	An event that is not necessarily significant, but might indicate a possible future problem. For example, when disk space is low, a Warning might be logged.
Information	An event that describes the successful operation of an application, driver, or service. For example, when a network driver loads successfully, an Information event will be logged.
Success Audit	Any audited security event that succeeds. For example, a user's successful attempt to log on the system will be logged as a Success Audit event.
Failure Audit	Any audited security event that fails. For example, if a user tries to access a network drive and fails, the attempt will be logged as a Failure Audit event.
