thats only with teleconverters normally

have you tried cleaning the contacts on the lens and camera body (a pencil eraser works well) - i'm a canon user so dont have any direct experience with the D200 but dirty contacts account for a number of error messages on canons and i wouldnt imagine that nikons are immune
