I've recently set up NT Challenge/Response for a particular folder on IIS 4.0. My problem is, I can't overwrite the asp files in this folder even though it appears as if it does - same timestamp, but the display is always the old one. I've actually deleted my files from the folder - but for some whacked-out reason, I can still access them from IE. I've even rebooted my machine, and I can still access the files I've deleted!! Is this an unpleasant side effect of NT Challenge/response?
