Following are some common problems and their solutions. I think it will help you :)
-if the error is of invalid login then the problem is with your user-name and password check them on the system
-Another common problem which we face during the use of app.config files is Firewall.
-Please check which authentication are you using is it window authentication or SQL authentication. I think SQL authentication will work for you


Its giving error
Object Reference not set to an instance of an object
But its working fine in visual studio
And want i deploy at user end it gives the above error
