We are running exchange 2007 on a windows 2008 server, both are fully
patched. We backup with Backup Exec 12.5, again fully patched. All of our
backups finish without any problems.

Our problem; when i restore a database backup to a RSG and then try to
restore a mailbox i recieve errors telling me that the maxium number of
corrupted messages has been reached. i tried moving the limit up, but i have
to move the limit up to 5000 before it works and then i only get a few
emails not the complete contents of the mailbox.

After a bit of research i found a few similar cases. These were resolved by
running the following command:

isinteg -s test -fix -tests alltests

i'm quite new to exchange and i have never used this tool. How can i run
this against the RSG? Will it help? Can i run the command as it is now
(changing the server name of course) or does it need a database agrument?

Thanks for any pointers
