How do NTFS permissions become improperly ordered?

Solution 1:

There is no one definitive way for them to get out of order, it can happen a few different ways. Some that I've run into:

  • Making a rights change and hitting cancel cancel OMG cancel in a panic before it gets done applying (kinda bad if you do it at the top of a 4-million file directory tree).
  • Command-line utilities (I'm thinking xcacls, I believe) that didn't respect ordering, you could shoot yourself in the foot easily that way.
  • Backup utilities that misbehave on restore.

There are probably more!
