This can happen when someone takes ownership of files\folders.

The only way to correct the situation is to take ownership as the administator (Local or domain) then reset the folder and share security.

One thing to verify is that ONLY the administrators have Full Control access to anything. Domain users and other groups should have change rights at the NTFS level.

So from the top level folders take ownership and have it Replace on all subfolders and files.(Check box at bottom) Let it do it's thing. Depending on the number of files involved this could take some time. Once complete change the security on all shares to Domain Users Full control, IMPORTANT!!! ONLY DO THIS TO THE SHARE. This allows you to use NTFS to control the file access at a more granular level.
Now change the NTFS security on the folders to what you want. Again make sure that the only groups that have Full Control at the NTFS level are the Administrive level accounts. This might also be a good time to verify that you domain administrator user group isn't bloated with people who have no reason to be there.

Hope this helps.
