After deploying my web application in server IIS 7.5.

And when I am trying to run it It's showing the error like.

500 - Internal server error.
There is a problem with the resource you are looking for, and it cannot be displayed

In my local it's working fine. through google I came to know that error lies in web.config file..but I could not solve it.

Here's my server web.config file.
