BUG - Renaming a Folder Causes NTFS Permisions to reset
I just renamed a top level directory on 5 of our file servers. There is 40TB of data across all these servers. Renaming each folder took an abnormally long time, but eventually finished. Come to find out, Windows reset the NTFS permissions on the folder. I did this same operation on two 2008r2 servers and it worked just fine. Windows should not being changing permissions on a simple folder rename
