Unknown Entry - S-1-5-21-2533013469-2641548184-613786714-1000

I have recently discovered the entry
S-1-5-21-2533013469-2641548184-613786714-1000 in the security setting
section of the Properties box when i right click on an object, be it a
program or a shortcut.

This entry show a person with a qiestion mark next to it, I do not remember
adding it and it appears to have special permission attached to it. I have
tried to get rid of it however some items such as the boot area refuse to
let go of it.

1. What is this ?
2. how to get rid of it competely ?

Thankyou in advance

Hello,

This represents a user that does not exist in your windows installation. It
could represent a user on a different installation of Windows. This can be
expected if the file was created in another Windows installation.

<snip> Not really.

Do you know where the permission originates at? What I mean is, you see this
permission on a folder. Go up to the parent folder, and check to see if it
is there as well, and keep doing that until you either find a folder that
doesn't have that permission or you hit your hard drive.

Once you find out where the permission originates at, you should be able to
remove it from that location's permission list by going to the security tab,
clicking the edit button, clicking the permission, and clicking remove.

It seems to only apply to the drive that windows is installed on. Have Tried
to remove it and Boot files and a few system files won't let me delete the
account. It appears to start at the root folder, in this case C:\. It hase a
special permission attached to it. I have sent an email of to NEC because,
if I remember correctly it was already active when I used the Recovery
Disks.

I am still seeking help form all here as well as NEC.

Please explain how it does not let you remove the permission. List what
actions you take, and any errors you get. You should be working with the
security properties for drive c, it sounds like it is inheriting this
permission from it.

I have tried to remove is as perscribed in windows help, however when the
files, as described before, are encountered windows returns a access denied
error but it soes allow me to continue. Widows warns me at the end of the
procedure that the permission may not be set correctly for some files and
windows basically dosen't like this.

As far as I can see it is a standalone with not inherited attachments. Even
if I change it to my security setting that wass setup when i configured
windows after using the recovery disks, windows will allow it but some files
still remain on this setting.

I have also checked on my other computer and found that this setting does
not exist in it, so I am thinking that it must be somthing to do with the
Recovery disks as my laptop has a fresh install on it and the origginal
installation disk was used not a recovery disk.

Hope this helps

So if I understand you correctly, you have removed the permission on all
files except for some system files, which have returned an access denied
error.

It sounds like Windows Resource Protection is blocking the changes to the
protected system files.

You will need to take ownership of the files left in order to be able to
edit their permissions. To do that, click advanced on the security
properties page, click the owner tab, click edit, select administrators, (do
NOT check the box next to replace owner on subcontainers and objects if it
is there), and then keep clicking ok until all the properties windows are
gone. Re-open the security properties screen, and you should now be able to
remove the permission.

Ideally, you should change the ownership back to the owner that was there
before, once you are done changing permissions (unless of course the owner
was the unknown account). To reference the trustedinstaller user, you must
use "nt service\trustedinstaller" for the user name.

I would point out too that this extra permission is harmless, it sounds like
it's just a side effect of the way they imaged the recovery CD, though
there's nothing wrong with removing the permission, as long as you keep the
rest of the security settings intact (including the inheritance structure).
