Mysterious file & folder "owner".
Recently my system crashed and 'system restore', repair from Vista DVD and
sfc /scannow were unable to recover my system except to take me to a
temporary desktop. This did enable me to copy both of my internal drives to
my external drive.

Then, with the guidance of a Microsoft tech, I was able to re-install and
activate Vista Ultimate. It did change the drive letters but I had named the
drives "C as of..." & "D as of..." so I knew which had really been the "C:"
drive. As I did not reformat most of my files remained intact but, of
course, I did have to re-install all programs.

When I started getting 'access denied' messages I decided to take ownership
again of all drives but I discovered that the current owner of my external
drive had become "S-1-5-21-3581062555-3082721082-2155200769-1000".

I had taken ownership of all drives and subcontents several months ago. I
have allowed both Microsoft and Symantec Tech Support to have use of my
system during help sessions via the internet since then. Other than that
only my wife has access to my system and she knows nothing about computer
science.

Does anyone have any idea who this
S-1-5-21-3581062555-3082721082-2155200769-1000 could be and how my ownership
status could have been usurped?

Is there a way to lock my ownership so it cannot be changed without my
permission?

My firewall is Norton Internet Security 2008.

Thanks for any help with this mystery,

Norman Castel

RE: Mysterious file & folder "owner".
S-1-5-21-3581062555-3082721082-2155200769-1000 is your user account on the
installation that broke. S-1-5-21-3581062555-3082721082-2155200769 is the
identifier of the computer, and 1000 indicates that it was the very first
account created on that computer. Every time you reinstall the computers ID
(called a Security Identifier or SID) changes. All access control is tied to
the SID. Therefore, when you move the drive to a different computer, which
you effectively did by flattening the original installation, it cannot
resovle the actual name associated with that SID because the account no
longer exists.

And, this question actually is answered in the book. :-)
