admin password not working  User name = admin     Password = admin123!

 You can do the following things:

1) On Submit_Click event of the login form submit button write code to test if a user with this username and password exists or not ,if not then throw a errormessage.In this way you will be able to determine whether your entered login details are correct or you have actually mistyped it.
