    Details

    Error:  "Name of database connection must be specified. Default database must be specified if an application server exists." when launching ITSM 3 tier connection.


    Resolution

    This error happens when the 2 tier connection gets  changed and is not synced with the settings in the web.config file  (C:\Program Files (x86)\FrontRange Solutions\Service  Management\ServiceManagement)  - see below screenshot for path and  setting.
    Verify the correct connection name is listed and correct if needed and reboot the server after the change.
