SYMPTOMS
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.
CAUSE
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.
