I'm running Exchange Server 2007 on Windows Server 2008. I see the following event logged when trying to mountthe public store database:Source: ESEEvent ID: 455Category: Logging/RecoveryGeneral: MSExchangeIS (2144) Second Storage Group: Error -1811 occurred while opening logfile C:\Program Files\Microsoft\Exchange Server\Mailbox\Second Storage Group\E0100001655.log.I hadseveral premature shutdownsto repeated power failures / battery exhaustionin the past month, which appears to havecaused some file corruption here. I do not have backup copies of my Exchange Databases. (I'm using full disk images for backups), so I expect I'll need to use eseutil to make repairs. Please advise if this is the correct approach, and what sytax is required.Thanks.

Hi Richard,it seems you have got a currupted log... if you got only the Public Folder databases under Second Storage Group, move the all the transtaction logs and try to mount the database.also you can check the state of the database by running eseutil /mh "path and database name"if its in dirty shutdown.. you can restore from backup or repair the database;Cmds-------- eseutil /mh "database path and name" to find the state eseutil /p "database path and name" to run Hard repair eseutil /d "database path and name" to run offline Defragmentationisinteg -s servername -fix -test alltests please refer "Repairing a Corrupt or Damaged Exchange 2007 Database Using Eseutil" under the following article "http://www.msexchange.org/tutorials/Configuring-Exchange-Server-2007-Preview-Chapter9-Disaster-Recovery-Exchange-Server-2007.htmlNote: Before proceed with repair make a copy of the edb file eseutil needs to be run on the cmd prompt from the bin folder eseutil can run max 10GB per hourRegards,Hari

OK, that was easy. Thanks. I just wanted to make sure I was on the right track before trying anything.
