$.get() and $.post() in MVC app works fine in local Cassini webserver but when published into IIS 7.5 it doesn't work anymore

Question

I'm actually stuck on this MVC application and can't find out the cause.

The code works fine in local Vis Studio 2013 Cassini webserver.

Hence when I type the URL in the browser: "/Customer/EnterCustomerDetails" then I'm displayed a simple form, a DIV tag containing status message "Loading..." and after 5 seconds some data via EF is returned due to the $.get() script that gets executed.

However, when I publish the same code into IIS 7.5 running inside Windows 7 Ultimate, then all I see is the form and only the div tag that displays the message "Loading..." but no data is displayed and it seems the $.get() is not working in the full blown IIS and neither is $.post().

Where am I going wrong? Any help much appreciated. Thanks in advance.

Posting this as an answer so that you can mark it as answered.

That sounds like the identity in your IIS app pool is not authorized for database access. Either assign a new identity that has permission, or grant access to the identity you are using.
