Internet Access from local Win2K Server

Hi,

I need to set up a local Win2000 server
(local IP address range, local domain name),
but still be able to access the Internet
through an ISDN router.

I learned from a previous question I posted,
that I should not enter my ISPs DNS server
under TCP/IP properties, as this gives a lot
of DNS calls. (Thank you, Andy_P)

How do I then access the Internet? I set up
a domain .local, and I understand
I have to set up the local DNS server as a
root server. In the answer to my previous
question, Andy_P told me to check for “DNS
Forwarders”

What is this, and how do I set it up?

Thanks a lot!

-Rolf.
