dns setting questions ??

[People]

Hiya, I have one windows 2000 server (DC) at my company. We just buy a
hosting plan for our website recently, & we set the nameserver to our
hosting company as well.

However, now when I try to ping my domain (xxx.com), it's still pointing to
our 2000 server which should be our hosting server instead. That's mean it
will point to our networks WAN IP. And this case only happens inside our
company (inside our network). When I try ping/access from outside or check
the setting from dnsstuff.com, it has no problems about this.

Therefore I am pretty sure it was the setting problem for our server. Could
anyone give me your help ?? Thanks !!

It's because a NAT device will not do a "U-Turn" when an internal request
goes to it's outside interface and the resource is internal. You need a
separate server if you are hosting your public zone on your internal DNS,
and it's behind a NAT device. It's a must to use a separate DNS server(s) to
host the public zone containing records with public IPs in your scenario.

For your internal zone (whether or not you have AD), you will use the
"internal" DNS server that only hosts records with their private IPs.

Basically, you CANNOT mix public and private records in the same zone under
the same server.
