Login failed for user IISpppool default apppool

In this tutorial we will learn how to solve Login failed for user 'IIS APPPOOL\DefaultAppPool' or System.Data.SqlClient.SqlException problem in IIS7. 

Basically This problem comes when we work with Asp.Net Application With IIS Server. I got this error while working with Asp.Net MVC Application. When I run My MVC application suddenly i got this error

“System.Data.SqlClient.SqlException was unhandled by user code:  Login failed for user 'IIS APPPOOL\DefaultAppPool’” and database connection couldn't open.

There are some step for solving this problem.

When you will click on this Path three dotted button there a window will open from there “Built-in-Account “radio button contain a dropdown box , from this dropdown box you change this path and the click OK.
