This is a dominance issue. She's basically saying, it sounds like, "No, I don't wanna!" Even though this is a dominance issue, the worst thing you could do is go in, guns blazing, and smack her just for the sake of "showing her who is boss." She won't respond to that.
So, what you really need to do is make her more curious about you. Open her stall door (have a lead rope with you) and stand just outside the door. If she ignores you, crouch down and very.....very.....very....slowly, inch toward her hind end (but stay out of the kick zone!) and when you can, take the lead rope and flick her on the gaskin, under the flank, under the belly, etc....you don't want to hurt her or cause pain, but you do want to irritate her....enough that she looks at you like "WHAT do you want??" You'll have to use enough umph to cause an effect. When she looks at you, stand up, turn away and walk to the door. As soon as she looks away, crouch down again and repeat the process. The reason you go slow is because you want everything about you to be intense.....if someone approaches you quickly, it's kind of predictable, but if someone is slow and seemingly sneeky, you don't know what's coming and you want to keep your eye on them...same with a horse (a confident, dominant one). You want to get her curious about you so that she will offer to come over to you...then you can put the halter on. And make sure when you lunge her that you make things fun and interesting, not just boring circles.
