Accessing folders owned by another user? Linn Kubler 12-06-2007

As the earlier posts indicate, a creator of an object in the 20th
century legacy Windows is its owner what same cannot be denied any power
over the object.

Use of that power can be curtailed if the access is not local (ie. over
network share, or mediated by a web service, etc.).

To "see" what is there use any software, like NTbackup, that uses the backup
and restore capabilities, run in context of an account with those rights.

This is a network share and I thought I had curtailed her power by removing
the Full Control right. What else must I do to prevent users from removing
or modifying everyone else's rights to a folder or file?

This is part of my concern, how do I know that our backups are complete? We
use Backup Exec, when I look at the logs for that directory it shows it as
empty. How do I know it's not just being blocked from backing up the files?

Thanks,
Linn

If you have reduced all share level permissions to modify/change
at most, that should have done it.

Back it up as an admin using the built-in ntbackup, and then
restore to alternate location without keeping permissions.
If it is empty and the backup log does not show errors, then
that directory is empty.
