I restarted my exchange server the restart failed because of a bad Key board I had to power off the server and restart with a new Keyboard to get the server back up. When It did come up exchange would not mount the msg store because the Microsoft Exchange Information Store service was not running. the Microsoft Exchange System Attendant Service is in a starting mode and the information store is dependent on this service. I am not running Anti virus on the server and I have ran the tools to check the message store and its ok . I need help starting this service please.
