DNS server question

[CiD]

Hello.

This is my set up.

I am running windows 2003 server with several xp workstations. I have
an internal DNS server , as well as I use my ISP external DNS server
for Outside Queries. The internal DNS server has entries for local
computers and objects in my LAN and its not suppose to respond to
outsie queries. What I have done so far, which sort of works is to
enter three DNS servers in appropiate order in each of my work
station. Of course, I am sure this is probable not the right thing to
do.


I specify the first DNS server to be my LAN dns server IP address
followed by the ISP external primary and secondary server.

Sometimes, when I ping a Local Address in my network my LAN dns server
responds with the query, however other times the workstation bypasses
the inside LAN dns server and queries the exterior Server. of course,
this doenst work as its trying to locate a LAN workstation on the ISP
dns server which simply it will not work.

What am I doing wrong here, could someone be kind enough as to point
me to the right direction?

thanks in advance

In an Active Directory domain, you must configure your domain controller to
provide dynamic DNS, and it must point to itself for primary DNS. Also, all
computers which you join to this domain must point to the domain
controller's IP for primary DNS. The conventional way to provide Internet
name resolution is to configure Forwarders:

On the domain controller, go to Administative Tools/DNS. Right click on the
server and select Properties. Click the Forwarders tab and click the enable
forwarders box - if this is not available, delete the "." zone. Enter the
IP address of your ISP's DNS server and click Add.
