Which permissions do you mean? Right now I have a file on my share that
has these permissions according to the Advanced Security Settings
window:

Allow - Joe Smith - Full Control - <not inherited>
Allow - Domain Users - Read & execute - <not inherited>
Allow - Everyone - Read & execute - <not inherited>
Allow - SYSTEM - Full Control - <not inherited>

Joe Smith was the one who created this file.

However, I can log in as Jane Doe, who is a Domain User but AFAIK not in
the SYSTEM group, and modify that file.  As Jane Doe I am not able to
delete the file or change its permissions, however.  Why is Jane Doe
able to modify the file?
