Login failed for user 'IIS APPPOOL\ASP.NET v4.0'

Question

I have a web project (C# Asp.Net, EF 4, MS SQL 2008 and IIS 7) and I need to migrate it to IIS 7 locally (at the moment works fine with CASSINI).

Locally in IIS I ha

Answer 1

I ran into the same problem testing ASP.NET Web API

Developed Web.Host in Visual Studio 2013 Express Database created in SQL Server 2012 Express Executed test using built in IIS Express (working) Modified to use IIS Local (from properties page - web option) Ran test with Fiddler Received error - unable to open database for provider.... citing 'APPPOOL\DefaultAppPool'

Solution that worked.

In IIS

Click on application pool 'DefaultAppPool' Set Identify = 'ApplicationPoolIdentity' Set .NET framework = v4.0 (even though my app was 4.5)

In SQL Server Management Studio

Right click on Security folder (under the SQL Server engine so applies to all tables) Right click on User and add 'IIS APPPOOL\DefaultAppPool' In securables on the 'Grant' column check the options you want to give. Regarding the above if you are a DBA you probably know and want to control what those options are. If you are like me a developer just wanted to test your WEB API service which happens to also access SQL Server through EF 6 in MVC style then just check off everything. :) Yes I know but it worked.
