I really appreciate all the help. Are forwarders standard in setting up
DNS
servers? I have setup a few networks and never used a fowarder.

They are a standard option but not absolutely necessary to many networks.

Forwarders serve two major functions:

1) Performance (consolidating cache, avoiding trips across WAN lines,
using server [e.g., ISP] closest to the Internet backbone.)

2) Security -- when internal sensitive DNS servers either cannot (due
to firewalls) or must not (due to security policy) visit the
entire
Internet. (We really don't won't our DNS, especially our
DNS-DCs
visiting "EvilHackersRus.com", right?)
