Question

Hi I have the problem to successfully log in my application after deploy.
I am using ASP MVC default login and membership provider and it is working on my localhost.
But after deploy I am trying to log in, then error is shown.

A network-related or instance-specific error occurred while
establishing a connection to SQL Server. The server was not found or
was not accessible. Verify that the instance name is correct and that
SQL Server is configured to allow remote connections. (provider: SQL
Network Interfaces, error: 26 – Error Locating Server/Instance
Specified)

*Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more
information about the error and where it originated in the code.

SQLExpress database file auto-creation error: The connection string
specifies a local Sql Server Express instance using a database
location within the application’s App_Data directory. The provider
attempted to automatically create the application services database
because the provider determined that the database does not exist. The
following configuration requirements are necessary to successfully
check for existence of the application services database and
automatically create the application services database:

1. If the
   application is running on either Windows 7 or Windows Server 2008R2,
   special configuration steps are necessary to enable automatic creation
   of the provider database. Additional information is available at:
   http://go.microsoft.com/fwlink/?LinkId=160102.

2. If the application’s
   App_Data directory does not already exist, the web server account must
   have read and write access to the application’s directory. This is
   necessary because the web server account will automatically create the
   App_Data directory if it does not already exist. If the application’s
   App_Data directory already exists, the web server account only
   requires read and write access to the application’s App_Data
   directory. This is necessary because the web server account will
   attempt to verify that the Sql Server Express database already exists
   within the application’s App_Data directory. Revoking read access on
   the App_Data directory from the web server account will prevent the
   provider from correctly determining if the Sql Server Express database
   already exists. This will cause an error when the provider attempts to
   create a duplicate of an already existing database. Write access is
   required because the web server account’s credentials are used when
   creating the new database.

3. Sql Server Express must be installed on the
   machine.

4. The process identity for the web server account must have a
   local user profile. See the readme document for details on how to
   create a local user profile for both machine and domain accounts.*

If anyone knows how to resolve this, I will be really happy.
Thank you!

Answer 1

if you deploy this to an external webserver you must adjust your connectionstring settings in the web.config
