Did you try to calm her or punish her when she acts like that? When you counsol her you are allowing acceptance of the behavior and she may interprete it as a positive re-enforcement but if you picked her up and slammed her on her back with you straddleing her all the while screamming at her she would see you as alpha and most likely pizz the floor but she wouldn't behave like that again while you were there.

Also, one trick that worked with a Shepard we had was to keep a bag of treats by the door. When someone came over they would give him a treat. After a few visits the dog was all about having people over.
