Bad public user name or password. Database Server Error: SQL Network Interfaces: Error Locating Server/Instance Specified [xFFFFFFFF]. ;

Can anyone help me on this?

    Hi
    This message is, when the connection to the db-server doesn’t work.
    - physical: cabling, server down, ...
    - wrong adress for the database: name
    - wrong connection.

    Try to establish a new connection with a different alias name.

    Good luck!
