I have a SMB Server 2003 and during the installation of the AVG for Exchange, it locked up. Now, the Information Store won't start. I have no way of undoing the AVG for Exchange. There is nothing under Add/Remove programs. I have rebooted the server with the services disabled and started them manually to no avail. Also, when I look at the application event log it says "file corrupt". I am not too concerned about the application log, I need to have the Information Store mounted ASAP. Any help or suggestions are greatly appreciated.
