I have a Windows 2003 DC that has shares on it.

With the share permissions set to "Authenticated Users" having read access,
non-authenticated users can see files and folders too. Why? I thought
Authenticated meant only if you had a valid login and password.

I have a member server also running Windows 2003. It requires a login to see
any shares. If you double click it from "Microsoft Windows Network" a login
dialog box pops up asking for a login. Where is that set? I'd like to have
more of my servers require a login to see anything.

So what is it that you believe is "non-authenticated users" ?

I am not trying to be smart or turt, but we do need to get
this clear. Since as I understand it non-authenticated users
are only people that cannot present successfully a domain
account somewhere in the forest (and hence are anonymous),
I just want to make sure we are both after the same end result.

Roger,
Thanks for the response. I agree with your definition.

We have a single domain in the forest and all users do login.

However, a small office has opened up in the same building and the users are
not associated with the domain at all. They simply want to share the LAN
rather than have their own.

I took in my own personal laptop just to make sure that nothing was
available to them. I logged in locally. The laptop has not been joined to the
domain and, I did not authenticate to the domain.

However, when I browsed the network neighborhood, the server not only showed
up but, many of the shares were visible. I then changed the share permissions
from "Everyone" to "Authenticated users" and let it sit over night. I came
back the next day and, the shares were still visible.

I then took the "Authenticated users" from the share permission and added a
single group or user and, I no longer had access form the laptop.

I thought it was interesting that the member server required a login to see
any shares at all.

Thanks for the help.

steve

The only way that makes sense to me, assuming when you say that
they could see the shares you mean they could see within them (not
just the share names) would be if Guest were enabled.
That would then qualify as an Authenticated Users member.
If it had happened due to the policy to let Everyone permissions
apply to anonymous, then after you changed from Everyone to
Authenticated Users one would have expected behavior that you
saw once changing from Authenticated Users to explicit groups.

I haven't checked this myself, but as I understood it, MSFT eliminated the
Authenticated Users SID from the Guest token back in Win2000 (it was present
in WinNT 4 though).
