Another thing you can try is to put her poop out in your yard (even if she goes in your house). That may help her understand that she is supposed to go out there. Obviously she's got it backwards in her brain because of being kenneled so you are going to have be more creative with teaching her.
Is she pooping in the same spot in the house? Can you block off all of the places where she's pooped in the house? How are you cleaning the area?
Instead of crating her, have you tried leashing her to you?
Sorry this is so tough: when I adopted Kai he thought he should pee in his crate and on the dog beds and in the back of the truck so I do understand your frustration...
