Recently we had our exchange 2007 server fail. Reinstalled exchange on a new server and attempted to restore the mailbox database to a Recovery Storage Group with Backup Exec 12.5 The restore seemed to work until I attempted to mount the database.

Received the following error when trying to mount the restored database in the EMS TA.:

Error encountered while trying to mount the database

Error encountered while trying to mount the database (Mailbox Database) in the recovery storage group (Recovery Storage Group). error message is Exchange is unable to mount the database that you specified. Specified database \WIN2K8-EX\Recovery Storage Group\Mailbox Database; Error code: MapiExceptionCallFailed: Unable to mount database (hr=0x80004005, ec=1276)

In the event viewer I see the following errors:

Event 1088, MSExchangeIS
The information store could not be loaded because the distiguised name (DN /O=LAN/OU=EXCHANGE ADMINISTRATIVE GROUP (FYDIBOHF23SPDLT)/CN=RECIPIENTS/CN= of message database "Recovery Storage Group\Mailbox Databe" does not match the DN of directory /O=FIRST ORGANIZATION/OU=EXCHANGE ADMINISTRATIVE GROUP(FYDIBOHF23SPDLT)/CN=RECIPIENTS/CN=.
The database may have been restored to a computer that is in an organization or site different than the original database.

Event 9519, MSExchangeIS
Error 0x4fc starting database "Recovery Storage Group\Mailbox Database" on the Microsoft Exchange Information Store.

Event 9518, MSExchangeIS
Error 0x4fc starting Storage Group /DC=COM/DC=LAN/CN=Configuration/CN=
Service/CN=Microsoft Exchange/CN=First Organization/CN=Administrative Group/CN=Exchange Administrative Group  (FYDIBOHF23SPDLT)/CN=Server/CN=WIN2K8-EX/CN=Information Store/CN=Recovery Storage Groupon the Microsoft Exchange Information Store.
MDB failed to start

I have search the web with various articles talking about scanning and repairing the database, but as far as I can tell the database is cleanly shutdown. It looks like the errors point to a difference in the organization name from the old server to the new server.

Any help you could provide would be greatly appreciated.
