Hmm,
I have the same problem but I cannot fix it with adding the “testdb” name in the “Connect to database” field.
If I fill in “master” it works. But why dows it not work with “testdb” which is assigned to my “testuser”?

I can see this is not new but this articles saved my critical time today. I was doing file group maintenance on a server and brought the database online. I did not know that the database for default for that server. I could not bring it online. I searched google and get to your article. I reconnected to server in SSMS using option, I selected Master and I was in and was able to bring my database online. Thanks once again. Keep up the good work.

Options allowed me to connect.

Then ran :

ALTER LOGIN [domain\userGroup] WITH DEFAULT_DATABASE = master
GO

Thanks

Muchas Gracias Broeshhh.. Pero mi problema tenia algo mas… para aquellos que no les salio quizas es porque hicieron algo antes de que el problema surge por ejemplo en mi caso borre una bd que era usado como database x default sin darme cuenta por eso luego al no reconcoer esta database no me permitia, lo que hcie fue entrar con master como me mencioana qui y luego en vez de hacer el “ALTER” crear la base de datos que tenai antes por medio de Scripts.
ENGLISH: For people who still have the problem, maybe it comes becuase before having the issue, you move or configure something wron, in my case, i delete a database, db which was the default db so the solution was accesing by master and then creating again the old db by scripts….

Hi
Thanks first for getting me a step forward to start my SQL 2008 server
Now I am able to connect with master but not able to change the default user for the instance as it is offline
When I am trying to bring it on line it is showing the same error 4064 login failed
