NTFS folder permissions apply to any users that logs on locally or via a
share. Share permissions apply only to network users accessing the share and
for such a user the most restrictive of the two settings will apply. Share
permission of change allows a user to access the share and write and delete
on that share. If you do not need that then set the share permissions to
read which allows the network user to only read/list/execute.
Everyone in your situation would mean anyone that can authenticate to the
computer unless the guest account is enabled which could then potentially
allow everyone and anyone access to that folder. I usually change everyone
to authenticated users. That way if the guest account is enabled somehow
that folder is still protected from anonymous access. Firewalls are an
important part of network security but be sure to have a strategy for
malware prevention, detection, and removal and for keeping current with
critical security updates at Windows Updates. --- Steve
