Same problem with PHP 7.1.1 with Windows NT build 7601 (Windows 7 Ultimate Edition Service Pack 1)
i586

It looks like chmod does not work either. I noticed that IIS does not have direct permission to
access the file. Maybe to have access to the file, the direct editing is necessary. I used the Chmod
( chmod 777 ) for the file, but it was only applied in the directory, not being applicable to the
files inside that directory.
In my case, it was a case of file import by form  (move_uploaded_file($tmp_name, $prev)). 

$prev =  $dir. "/" .basename( $filename );
if(move_uploaded_file($tmp_name, $prev)){
    echo "Success!". $prev
}

The file is copied but is not displayed in previews. The file does not have the permissions for the
IIS_IUSRS user.

I have the same problems. PHP 7.1 NTS on IIS ...10? Running Windows 10. The workaround appending a
subdir + .. worked for me.

I have the same problem on Windows Server 2012 R2 and both PHP 5.6.24 and PHP 7.0.9. In my case the
DirectoryIterator::__construct was failing with Access is denied. (code: 5)

This bug still exists in php 5.4.36. win32 - Windows Server 2003, iis6. I can readfile, chdir but if
I try to read the files (scandir, opendir, DirectoryIterator) I get an access denied error.

C:/Website/ -- Not accessible
C:/Website/public_html  -- Accessible
C:/Website/public_html/etc...  -- Accessible

User has correct permission to C:/Website but no permissions for access on C:/.

That's correct, I forgot to add this info to this bug report (present in another 
one). It is required to allow the underlying Windows API to get through the 
directories while it won't allow the user to access it.

Issue still exists in 5.3.22

Workaround is to give the user under which the website is running (advanced) "list folder /
read data" permissions on the parent folder.
this is the only permission required.
