[Samba] Samba 4 + Samba 3

[Francis Guslinski]

Hello,

I have a samba4 running as ADS, domain logons and gpo's running fine. So I
want some features of samba 3 then I running samba3 in ADS mode, joinning
the domain in samba4.  Everything is fine to machines that are joined on
domain.

The problem is in machines that aren't on domain, i try access a share which
is public access ("guest ok = yes") on samba3 and it return that host of
samba3 is not found.

Some help?
