Product: Exchange

Message: process name (process id) %3The database engine stopped.

ESE Event ID 100 indicates that the database engine started.

ESE Event ID 101 indicates that the database engine stopped.

ESE Event ID 100 is usually followed by a series of other ESE Events

describing an online restore, or mounting of information store databases. 

If an online restore fails to complete, or a database fails to mount, you may

receive an Event ID 101, indicating that the database engine has stopped. 

You may also receive this event when an information store dismounts for any

reason.  If you try to mount the store again and the store fails to mount, you may receive Event ID 100 indicating the database engine started, and then

again receive Event ID 101, indicating the database engine failed to start. 

In Exchange System Manager, if the arrow points down and is red, which displays

on the Exchange System Manager icon, this indicates that the stores are


In summary, receiving ESE Event ID 100 simply means that the database engine

started.  It does not mean the information store will mount, since it may be

followed by an ESE Event ID 101, which means the database engine stopped. 

In this case, the store failed to mount.  The reasons for ESE Event ID 101

are many and varied.  These events by themselves are generic for restoring

and for mounting of the information store databases.

For examples of causes, there may not be enough permissions on the
directory where the database or logs exist to mount the store.  There may

be missing log files on the production, or in an online restore, there may be

old log files that are out of sequence with the log that is mentioned in

Restore.env file.  There may be file level virus scanning software running

against the log file directory.

User Action

In normal operations, if you receive ESE Event ID 100 or ESE Event 101, and

Exchange is functioning normally,  no user action is required.

However, if an online aware restore of Exchange fails or an information

store database fails to mount as expected, then ESE Event ID 101 indicates that there may be a problem with the database or its logs.  Check the Application

log and the System log for related events to determine the exact sequence of

events leading up to ESE Event ID 101.
