Hi There;

I have set up several networks with internal DNS servers..
Use a Linksys router between the cable modem and your internal
network.

Set up a W2K Pro or XP Pro box on the system

go to http://www.jhsoft.com and download Simple DNS

I personally use this as my secondary DNS works fine

I use a Cobalt Server as my primary internam DNS

You need to have lots of networking skills to do this
But it works for me

You have to consider what you plan on doing
I have 3 internal DNS servers here in my shop
just to be sure my skill are up to par when I set
up a network for a customer..

Once it is in place you will not have to worry
about your ISP DNS's and you can do lots of neat things
like assign internal domains to your different
pieces of equipment.

Hope this helps
