NTFS ownership stripped

Got a question on how the following happened.

I changed rights of users to not allow delete files and
subfolders. Applied the new set of rights to around
200,000 files and 15,000 folders. The process was not
interrupted. After it was done, a semi-random assortment
of files and folders had their ownership trait stripped,
(couple hundred of them)leaving them with no owner, thus
no rights, thus no access.

I've seen something similar happen when the rights change
process was interrupted by a power failure, but this time
the process seemed to complete normally and without error.

Any insight on this would be much appreciated as my client
is asking the much dreaded 'Why' question.

Thank you
 
That is a lot of files and folders to process and there is no way to know exactly
what happened or guarantee 100 percent success. I can hazard some guesses - there
were some corrupt files to start with or there was a "glitch" with memory or power
supply during that process which had to take some time or maybe a few bad spots on
the hard drive. The remedy may be to restore from backup and try the whole process
over, restore the orphaned files from backup and redo, or use subinacl to try to take
ownership of those files and then give them proper permissions. It also probably is a
good idea to do a thorough diskcheck before ever attempting such. --- Steve
