As the message says, either the credentials are wrong or that database don't exists on th SQL Server you are connecting to.
												
I guess the Configuration Manager in question has something to with Exchange? Olaf, is like me, specialises in SQL Server and may not know anything about this particular Configuration Manager. (I certainly don't).
What you do is to access the SQL Server instance and create a new database with the same name. But I guess this Configuration Manager will be confused when there are no tables.
Hopefully, someone from Exchange side can chime in.
