Event ID 3154 ‘Active Manager Failed To Mount Database’

KB ID 0000867 


Seen on an Exchange server, in my case I got one for the mailbox database, immediately followed by one for the public folder database.

Event ID 3154

Active Manager failed to mount database MailStore 01 on server {Server-name}. Error: 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).


1. On the affected server > Windows Key+R > ncpa.cpl {Enter}.

2. You should be presented with the network card for this server . right click >Properties.

3. ENSURE that IPv6 IS selected and has NOT been untucked.
