Answer 1

The error message you are receiving is telling you that the application failed to connect to the sqlexpress db, and not sql server. I will just change the name of the db in sql server and then update the connectionstring accordingly and try it again.

Your error message states the following:

Cannot open database "Phaeton.mdf" requested by the login. The login failed.

It looks to me you are still trying to connect to the file based database, the name "Phaeton.mdf" does not match with your new sql database name "Phaeton".

Hope this helps.
