What is the difference between success and failure events? Is something wrong if I get a failure audit?
A success audit event is triggered when a defined action, such as accessing a file share, is completed successfully. A failure audit event is triggered when a defined action, such as a user logon, is not completed successfully. The appearance of failure audit events in the event log does not necessarily mean that something is wrong with your system. For example, if you configure Audit Logon events, a failure event may simply mean that a user mistyped his or her password.
