Hi in the confusion of Google I cant seem to find a straight answer about
permissions. I know Authenticated users includes any user who has
authenitcated against a DC right? So if I wanted to add all my users to
access a share whats the diff between using Authenticated Users and Everyone?

Also, if I created a share and gave a certain Group, call it "Accounts" full
access to this folder. The Everyone or Authenticated or anyone group wont
give access to this folder through some kind of wacky way microsoft do things
or anything like that will it? The only way Authenticated Users will get
access is by either inhertigin it from folders above or my me adding that
group to the persmissions of that share right?

Yes, that is pretty much it in a domain environment. For a standalone it is
an account that has authenticated on that machine.

You would probably want to use Domain Users. Everyone would include
Guest if it is enabled and used, else it is pretty much Everyone (unless the
group policy setting that allows everyone to include anonymous is in use).
However, notice that these are all accounts in the forest, not just the
domain
where used, hence the comment about using Domain Users.

I am sorry but can you rephrase that ? I really could not fully follow what
was being stated. However, of what I could grasp it does not seem right
that you cannot directly set a grant but must cause it to inherit onto what
you want the grant set upon.

Not strictly.

In earlier Windows versions, Everyone includes the Anonymous group. Windows
XP SP2, Windows Server 2003, Windows Vista and Windows Server 2008 exclude
the Anonymous group from the Everyone group.

I'm not sure if this is a really clever idea, but it's a result of
administrators thinking that Everyone meant Authenticated Users. So now,
Everyone does mean Authenticated Users, and you have to specifically include
rights for Guests and Anonymous users.

Perhaps I should have quoted the "it" in my correction.
While your comment is true, I was not speaking of Windows back at
that level as should have been clear from the comment about using the
policy to revert to the legacy meaning (let Everyone include anonymous).
At this point, it has been so long I honestly do not remember whether it
was with W2k3 or with a late service pack to W2k where that change
first appeared, but if the later then the semantics of Everyone that you
mentioned would no longer exist in a supported Windows server version.

I think it is a result of the widely spread awareness of the hazards of
Everyone
among Windows admins back then (remember the default NTFS permissions on
new partitions back then of Everyone Full?) and our advocation to MS that
they
needed to approach things from a least privilege perspective.
Actually Guests is included in Everyone, only Anonymous must be explicitly
added, if desired. But I agree, in the evolution of Windows post-"security
push"
there are some artifacts that just don't really make a great deal of sense.
Now
that Everyone much less used in a default install, people tend to believe
that
the issues its use once lead to have been removed. Some examination of the
default uses made of Interactive and of Network that appears to glue things
together in the absence of the use of Everyone can however make one wonder.
