I ran into an issue the other day where a file on a network share ended up with its NTFS permissions being hosed in such a way that no one could edit, delete, or even take ownership of it. I’m not sure how it happened, but it did and the ticket ended up with me to get it fixed.
Nothing I did in the GUI could fix the problem. I could see the filesystem security attributes were hosed and nothing, not even taking ownership, would successfully complete. After a quick visit to Google, I found the Technet page for takedown.exe. It’s basically a tool for sysadmin’s to take ownership of a file with borked permissions. Perfect! That’s exactly what I need.
Unfortunately, it didn’t work and failed with a non-helpful generic error. Turns out I was having a case of the stupids and the file was locked by a crashed application. Killing the processes released the lock on the file and then I was able to delete the file and restore it from the previous days backup. On the plus side, I found what looks to be a great tool to keep bookmarked for the future!
