Last weekend, attempted to migrate our Exchange 2007 SP1 to a new server with the same AD name. Followed all whitepapers and resources and all went well until it was time to mount the databases. I only have 2 databases, mailboxes and public folders. Both failed. On Server 2003 x64. I've tried the following methods to resolve:1) Performed setup /prepareAD and results were successful2) Disabled Checksum offload with NIC 3) Move Translogs to different physical hard drive4) Manually confirmed domain\exchange servers had appropriate permissions in security policies (local and domain)5) Performed connectivity tests with BPA, results successful6) Ran eseutil /p - failed7) Restored mailbox .edb file and attempted re-mount failed Help?

See if this helps:http://technet.microsoft.com/en-us/library/dd159911.aspxEvent ID 490: Error Occurs When You Try to Mount the Mailbox Database or the Public Folder Database

That wasn't it.I later learned in a roundabout way - if you can't mount a database, use the shell. It'll work.
