[Samba] Migrate and Update (Samba 4.1 ADDC to Samba Latest Version on different Server).

[Juan Ignacio]

I ping DC2.OURDOMAIN.ORG from itself and work.

Its resolving localhost. 127.0.0.1

I ping DC2  and is resolving localhost too.


If i ping DC2 from DC1 the old server its resolving the address correctly
too.


Thx.
