i went there and there was no security tab , so i did what u said and enabled it , now i can see the tab .
i had to uncheck simple file sharing check box . does this compromise my system at all in any way . I am the only one who users this computer as it is mine .
in the list that appears under the security tab , there are about 5 items in it . Is it possible to have a delete check box there as that does not appear in that list .
and by checking deny all as you mentioned does that only apply to the file or folder i did it on ?
