DNS QUESTION. Please help

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

Ixnay. This is bad practice and will cause problems such as you describe.
All servers and workstations should specify *only* the
internal/AD-integrated DNS server's IP address in their network settings.
The internal DNS server should be set up with forwarders to your ISP's DNS
servers for external resolution and/or use root hints. See
http://support.microsoft.com/default...b;en-us;300202 for more
info.

See above!

The Domain Controller, assuming it is the DNS, should point to itself. All
other machines should point to your AD/DNS *only*.

The only place your ISP's NDS should appeart is in the Forwarders List
within the DNS Service's configuration.
