Hi All, I have just installed my first Exchange 2003 server and the Information Store will not start. The error in the event log is The Microsoft Exchange Information Store service terminated with service-specific error 0 (0x0). I checked on TechNet and they stated that the Exchange Domain servers group of the child domain should be a member of the Enterprise Exchange servers group in the Parent domain. I made the change rebooted the server and the same problem. Any ideas?
