Can you post a bit more of your code? I suspect that your connection string isn't right, as the server should respond in 200 mS easily. Are you using a local installation of SQL Server Express? If so, it should have a name for the instance, not ".\SQLEXPRESS." It may be that it isn't responding because it's never notified on the request. For instance, on my setup, the SQL Server installation is named "BAAL\SQLEXPRESS" and shortening the name in the connection string never works. The shortcut ".\" may not be valid for this application, so try adding the full name of the computer that hosts the server and see if that helps.
