One of our Exchange 2010 servers had its mailboxdatabases dismounted sometime during the night. When we tried to mount them we got a strange error message : “MapiExceptionNetworkError: Unable to make admin interface connection to server. (hr=0x80040115, ec=-2147221227)”
As we usually do with issued like this on Exchange is to check that all services have been started. Went into service manager and sorted on “Startup type” to see if all marked as Automatic startup was started, and they where. Next was to check all DNS records and Eventviewer. No luck. Rebooted server. Still no luck. Finally, a closer inspection, the “Microsoft Exchange Information Store” service was set to “Disabled”. Enabled and started it. Now it was possible to mount the databases. How it ended up being disabled is another issue, perhaps some update did it..
Couldn’t mount the database that you specified. Specified database: MBXDATABASE; Error code: An Active Manager operation failed with a transient error. Please retry the operation. Error: Database action failed with transient error. Error: A transient error occurred during a database operation. Error: MapiExceptionNetworkError: Unable to make admin interface connection to server. (hr=0x80040115, ec=-2147221227)
