Exchange Information Store Corrupt with Database not found Error


									In several Exchange database operations, like (but not limited to) backup
process, the operating system is called to read database pages that have
to be written on disk. During this operation, the checksum value placed
in database page header is compared with that returned by READ operation.
The backup operation fails if these values do not match. Such errors
indicate corruption in database and need backup availability to restore
lost data. But in cases when user finds it unfeasible to restore from
backup (because it is corrupted or incomplete), a Microsoft Exchange
Recovery tool can help.       To depict the probable events, let's take a
related scenario of an Exchange Server 2003 user. When he runs a backup
utility to copy the Exchange database, the operation halts with an error
that reads:

   -œDatabase was not found and could not be backed up. Please make sure
database exists and is mounted.-•       The logs also consist of errors
such as:       -œStore_Name is a corrupt file. This file cannot verify.-•
Or       -œAccess is denied. Access denied to database Mailbox Store.-•
On exploring the application event log, it shows error -1018.       Cause
The root cause of the above behavior is corruption of Exchange mailbox
store, most likely due to hardware issues. These errors cause checksum
errors in database pages.        Solution      To resolve the problem:
1. You need to run system hardware diagnostics to find the root cause and
then isolate the related issues.       2. User can create a new mailbox
store and move the mailboxes from the corrupted store, to correct the
database problems.        3. You can also try repairing the corrupted
database using Eseutil/p repair utility. However, this command is often
unrecommended because it deletes the corrupted database pages and can
cause important data to delete.       4. And, for safe database repair,
use an Exchange Recovery Tool. Designed to run safe scanning procedures,
these Microsoft Exchange Server Recovery software can repair corrupted
database and extract valuable data.       Exchange Server Recovery
