Hi Louis,

I don't use DHCP so most of what you wrote doesn't apply in my case.

As for the reverse zone: I followed the wiki in this respect and do have 
a reverse lookup zone for the network, pointing to the DC.

RLZ: 0.168.192.in-addr.arpa
NS dc samdom.com
SOA [2], dc.samdom.com, hostmaster.samdom.com

Let me know if you see any issues in this configuration, thanks.
