Everything went well with the image but the info store and public folder store cannot be mounted. It gives the error message: the database files in the store are corrupted. ID No: C104173b. As I only have one exchange server within quite a small domain the exchange server is on the domain controller. Could it be that I should have restored the active directory and then the exchange server separately?

Hi, Only the 1 DC, this is all testing in case of a DR situation so the exchange is isolated aware from the network. The Imaging software is supposed to be exchange aware but I'm wondering if I've missed something simple with a hardware issue.
I thought the same about restoring from tape so took a back up of exchange using Symantec Backup Exec on an LTO3 tape but think I might have stumbled across another issue as when I try to restore using Window NT backup (on the temp server as Symantec not installed) the store appear empty! Would this be because I have to have symantec backup exec available to do the restore? Sorry I think that's just turned into another question.
HI there,
Although both Symantec and NTBackup create BKF files, they are (not to my knowledge) compatible. NTBackup is actually a cut-down version of Backup Exec, going back to when it was Veritas, but like I say - if you've backed up with Backup Exec, you'll have to restore using it.
All you need is the backup Exec remote agent installed on the Exchange server and you should be able to restore the DB from the media server.
1.
+ Check the consistency of the database with eseutil /mh <database_complete_path>
+ If they are okay just move all the log files out to another directory and try to
+ mount the store .
+ They will mount and create new log files.
+ This will allow the store to mount
2.
Cause:- Log files corruption "Transaction Log"
> Move all the transaction logs and the res1 and res2 files to a backup folder
>Mount Blank Stores - Will Mount
>Now try Mounting Store with Old Database - If it says database is inconsistent
>Run eseutil /mh - Check fi its Dirty Shutdown
>Run Repair on the database "Eseutil /p"
>At the end of repair it might sit on :Deleting unicode fixup table - thats normal... "Wait until it shows the database has been repaired"
>Mount the stores - it will be good

HI there,
Firstly - do you have more than one domain controller? If so, then imaging was a bad idea. You should never image a domain controller. You can enter a state known as a USN rollback which can cause you problems. However this caveat only really applies if you have more than one DC - As you said 'the' domain controller, I'll assume that you only have the one, though.
I would recommend restoring the Exchange DB with a 'standard' backup, such as NTBackup of whatever you use to backup Exchange. Again, imaging of an Exchange database is generally a bad idea, as it is not Exchange 'aware' - it will not flush log files etc.
When you restored the partition holding the DB, did this also hold the log files for Exchange?
I think it may be best to simply perform a 'normal' restore of the Exchange DB now, this should hopefully fix things.
