Login failed for user 'IIS APPPOOL\dev.newapp.com'. I have checked the User Mapping properties and both applications are listed. I did not make any changes in IIS or the SQL Server. Also, I tried changing the Identity in IIS for DefaultAppPool to LocalSystem with no luck.

If one uses trusted connection to a sqlserver database under Windows 7 and II7 one might get the error message "Login failed for user 'IIS APPPOOL\DefaultAppPool'." when trying to run a web application. There are several articles for this but all points to a different GUI than mine (earlier versions of Windows7/IIS7?).

What you want to do is go to your SQL server, and add an SQL login for "IIS APPPOOL\DefaultAppPool". The reason MS stopped using NETWORK SERVICE or LOCAL SYSTEM is that there can be security issues between processes sharing those accounts.

Take a look at the Application Pool used, in this case DefaultAppPool. 2.Now that you know the application pool the website uses, instead right click Application Pools (in IIS root) -> right click the correct application pool -> choose Advanced Settings.
