Exchange 2007- Information Store and System Attendant does not start.

A customer of mine had  a peculiar the other day 🙂

In a mixed enviroment with Exchange 2007 and 2010 the System attendant and Information store did not start on the 2007 server after a reboot..

In the event log we got this very describing message “The Microsoft Exchange Information Store service terminated with service-specific error 0 (0x0).” , event ID 7024.

Normally this has to do with permissions to registry keys or permissions on objects in AD (you can find a lot of solutions on this on google). But i checked all permissions and they where OK.

Further back in the eventlog i found som error messages caused by a skew in time. these messages was triggered by “The Microsoft Exchange Active Directory Topology service”.

Ran win32tm /resync and checked that time was the same as on the domain controller.
Rebooted with no luck 🙁 …

The solution was :

1. Stop all Exchange services.
2. Start “The Microsoft Exchange Active Directory Topology service” first.
3. Start “Information store” and “System attendant” + (other Exchange services incase SA doesnt start them)

I do not know if the error occured because of a skew in time between the DC and Exchange or if it was just  a coincidence. The reboot after the timesync should have brought the services up in that case.

Anyway, it worked and in a couple of days we are going to decommision that 2007 server 🙂
