The Everyone group has (in effect) as a subset the Users group,
which often itself has as part of it the Domain Users group.
In W2k Everyone has a more broad definition than it does in
the default config of XP and Windows .Net. In these newer
systems anonymous connections are specifically excluded from
Everyone (making it difficult to distinguish Everyone, in its
default form, from Authenticated Users). In the heritage systems
Everyone is effectively an indicator of any token that can be
used for a process, even when there is no identity. Right or not,
for the heritage systems I think of Everyone as Authenticated
Users (which includes Guest) + Anonymous User.
