If the Exchange server and the computer without Exchange Server are not running the same Windows NT version and service pack, you may see events in the Application log that indicate that the database indexes are being re-created upon restarting the database service.
Ive seen in the past that its a normal practice of Exchange admins to perform offline defrag aka eseutil /d on exchange databases.. But, is it really worth the time taken and downtime planned ??
