I am starting with framework 4 and VS2010 (MS Windows Server 2008 R2 + IIS 7.5). On same server I have SQL Server 2008 which have to access with Windows authentication.
This is my connection string:
<add name="Server" connectionString="Data Source=Server;Initial Catalog=database;Integrated Security=SSPI" providerName="System.Data.SqlClient" />
I enable only Windows security in IIS Manager-Authentication.
When I try to load aspx page with gridview (only select command) I got this error:
Login failed for user 'IIS APPPOOL\ServiceApp'.
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: Login failed for user 'IIS APPPOOL\ServiceApp'.
I have no problem connecting to this server from SQL Server Management Studio with Win Auth.
What else do I have to do to connect to sql server from my app?
