Hi, I have quite a problem on my hands and have been working on it for a few hours with no success. Firstly i dont have a recent enough backup, so i cannot restore. (i know, but there is nothing i can do about it now) The machine went a bit screwy over the weekend and was stuck on a reboot screen when they came in this morning. Everything but exchange came right on a hard reboot. The EMC tells me that "Mailbox Database" is dismounted.
