My bro has had the following problem where he works...
Here's the problem. 11.30 yesterday all our internet servers appeared to stop working. Turns out that the reason for this is the services no longer had NTFS file access to the data (accessed as a network share). The user permissions had simply disappeared, or rather been replaced with "Unknown User". Note the user account was not corrupt as it had access to other shares on the system.

I know how to manually add the permissions back, but this is taking ages (over 200,000 files !).

My question is HTF did the user permissions get corrupted without human intervention?
He's posted this on Pistonheads but asked if any of you guys and gals could shed any light on this.

Ta muchly

It could be possible the SID's for the files got corrupted in some way such that the operating system cannot match them to an account.

Cheers ajm. What can cause these corrupted SIDs? An undocumented MS 'feature' perhaps?
