OU Group Policy Not Applying to User

W2K Pro clients – W2K SBS — I have one new user I set up in an existing OU that has a GP. The GP will not apply to this user. It does not matter what PC she logs in at, she gets the same results. The login script does not run therefore she is not getting the mapped drives she needs. It works fine for the other users in the OU. I even blew away her id and recreated it by copying from another user in the same OU. Why is this happening to this one user, and how do I get it fixed? Thank you for your help!
