Change wordpress login location of page

I have already read other posts such as this one : http://wordpress.org/support/topic/how-to-change-the-location-of-wp-login?replies=3 and I have not found my answer. I want to change the location of the login page, so if people try to find the default login page, “wp-login.php” they get a 404 or an error. I would simply like to make it something like “wp-adminloginpage” or even “wp-administratorloginpage”. Something really hard to guess. I know I can’t do something like domain.com/login because that would just be a page. Any ideas?
