Folders with no access - no longer visible

[DavePa]

Odd one in case anybody else comes across it but I've noticed that on a newly imaged Win7 machine (Image created yesterday, includes all updates) folders that the user has no access to are not even visible. We have a folder that is used by a number of people and there are 3 folders within it that have further NTFS permissions set to allow access to only a handful of people. On other machines these folders are visible but trying to access them gives, as you would expect, an 'Access denied' error. Using the image that was created yesterday however the folders are not even visible which is a far better solution and something that should have been done years ago!
