Put her in her room at a decent hour and tell her to stay there. If she doesn't put up baby gates in the doorway or continue to take her back to her room. Make sure she doesn't have any toys to play with and it's nice and dark. If she's bored and sees that nothing is happening, she will go to sleep. It may take a few nights of screaming, but she will eventually get that you mean business.
