So, what? Go to top directory properties, Advanced, Owner tab, Change, and
change the owner to what is desired.

If you write these SID's it would be easier to tell.

As Corinna said, this can be fixed, you just have to fake a valid UID for old
user to jumpstart the process.
Obviously, you would need to run the script as administrator account to work
on the permissions changes.
