Event 102 signifies that an instance of Jet has started and indicates which instance has started. Event 103 indicates which instance has stopped. These events can occur in the ordinary operation of a Microsoft® Exchange Server environment, or they may be associated with errors. An error is never mentioned in the description section of event 103. Event 104 definitely indicates that there is a problem and that the named instance of Jet has stopped with a definite error associated with it. The error is named in the description section of event 104.
