Kind of desperate for some help here.
The Microsoft Exchange Information Store service will not start and the event log says: "The Microsoft Exchange Information Store service terminated with service-specific error 0 (0x0)".
I have been working on this for hours and have not been able to fix this. I have already followed http://support.microsoft.com/kb/285116
but it did not help. Some previous entries in the System error log are showing that some services cannot start due to a missing file so I am confident that the store service is being affected by something like that as well...but I did a full C drive file restore using ntbackup and it didn't help.
