Problem with db connection

My application works properly with development area (VS 2005) , When I created virtual directory and call using browser (IE 7.0) , error occurs exacly the same below

ERROR:

Cannot open user default database. Login failed.
Login failed for user 'CBOZLAGAN\ASPNET'.

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.

Exception Details:System.Data.SqlClient.SqlException: Cannot open user default database. Login failed.
Login failed for user 'CBOZLAGAN\ASPNET'.

Source Error:

Line 4932: this.Adapter.SelectCommand.Parameters[2].Value = ((int)(PROFIL));Line 4933: neuron.KULLANICI_TANIMLARIDataTable dataTable = new neuron.KULLANICI_TANIMLARIDataTable();Line 4934: this.Adapter.Fill(dataTable);Line 4935: return dataTable;Line 4936: }

Connection String is below

"Data Source=.\\SQLEXPRESS;AttachDbFilename=C:\\neuron2007_AJAX\\App_Data\\neuron_Data.MDF;Integrated Security=True;User Instance=True";

How can I solve this problem?

Thanks

Did you grant the ASPNET user account permission for the database?

Are you publishing to a remote server and are you publishing a copy of the local database that you are connecting to in that connection string?

Did you grant the correct permissions for Integrated Security?

Yes BRCK231\ASPNET has rights below

- db_datareader

- db_datawriter

But connection is done with user BORINTERNAL\CBOZLAGAN for BRCK231\SQLEXPRESS sqlexpress 2005 server

Is the website set up (via IIS) to accept anonymous connections? If not, please give that a try.

Did you figure it out yet?
