Instance 8: The physical consistency check has completed, but one or more errors were detected. The consistency check has terminated with error code of -106 (0xffffff96). I get error 401 and 403 twice every time we run a backup. We are running Windows 2008R2 and Exchange 2010. We are using NovaStore v14 backup software with an Exchange plugin. What should I do about this error? Thanks.

That error code seems generic and doesn't necessarily indicate that you have any logical corruption within the DB. It can be hardware related or software related within the back up application. I would look into their knowledge base or contact their support before going down the route of doing any database maintenance on your Exchange DB.James Chong MCITP | EA | EMA; MCSE | M+, S+ Security+, Project+, ITIL msexchangetips.blogspot.com

Thanks....I suspected that. I'll try them first.
