[SOLVED] SERVFAIL error on DNS resolution

[AngeLOL]

You're going to sleep relaxed having disabled the firewall on your machine and left it wide open?

Yes, because I really needed the DNS server working for this morning.
Along this week I´ll be working on the security of the server, I'm studying engineering, and this months we'll be working on security in class
