Kevin,
What about file permissions?
I think the Web contents are delivered based on an intersection of IIS and file permissions. Given that you've reformatted and installed everything, permissions may have been altered for a number of reasons (e.g. FAT partition that is now NTFS, new account SIDs, etc.)
