High GPA vs. Course Retakings

I've got a question regarding academic records. I've got a pretty respectable GPA (~3.7), but I also have a couple of courses that I either received a grade and retook or withdrew from the course. Specifally, I earned a C- and a C in another class and chose to retake those. I also have a withdrawal in another class. While the grades I earned in those classes aren't horrible, I still feel they might be a liability on a transcript for a top business school. I was wondering how top business schools view GPA's in light of circumstances such as those outlined that influence them?
