After you complete an installation of Exchange Server version 5.5 over a previous version of Exchange Server, or upgrade Exchange Server version 5.0 Service Pack 1 to Service Pack 2, the following events will be logged in Event Viewer and will appear to be a problem with the installation:
Event ID: 1005 Source: MSExchangeSA Type: Error Category: Monitoring Unexpected error <<0xc0040000 - The Microsoft Exchange Server computer is not available. Either there are network problems or the Microsoft Exchange Server computer is down for maintenance. Microsoft Exchange Server Information Store ED no.: 8004011d-0526-00000000>> occurred.
Though the event appears to be a problem with the server, it is actually an expected behavior. The Exchange system attendant is attempting to contact the information store, which is not available at the specified time. After the Exchange Setup program has completed, it begins restarting all the related services. When you check further in the Event Viewer log, you will see a display of the successful startup of the information store, as follows:
Event ID: 1001 Source: MSExchange IS Private Type: Error Category: Monitoring The Microsoft Exchange Information Store has started. Service startup complete, version 5.5.
