SQL-Server-2014

I am using sql server 2014 to perform database operations, and it is working fine when I run from visual studio localhost. But when I put my web application on IIS on my system only, it is giving me error : The underlying provider failed on Open.

Both, application and database on single system. I googled it too, and I already followed this link,
Solution for "The underlying provider failed on Open" exception.[^]
But it's not working in my case.

What other changes I need to make to make it work. ?

you said the solution from the link didn't work for you - so you are SURE you don't have authentication problem, correct? - really? ;-)
