Ladies and Gentlemen,
I ran a restore from tape and tried to start the IS with this error:
The Microsoft Information Store service terminated with service-specific error 4294966746
Event ID: 7024
Source: Service Control Manager
I run restores all the time for people who "misplace" emails. We recently installed sp4 for exchange 5.5 as a fix for an oversight. Oversight being: When sp4 was installed on exchange servers, it wasn't installed on our recovery server.
Before I got the error listed above, I got the error 3355445011 indicating the RestoreInProgress registry key. I deleted the key and tried to start IS. Now here I am...
