Why it is not working despite follwing all the steps as mentioned above

Anytime you have a client-server application that gives you problems, supplying just the client-side error message rarely helps you get an answer. Have you looked at the server's log to see what error is reported? If you cannot make out what the error means, post the server-side error message on the forum; you might get a solution or a pointer to the solution.
