Can someone help walk me through DNS.

I have tried multipule times to setup up a test 2k server. It seems to always fail when I am setting up DNS. So if someone can help walk me through each step that would be great. Right now I have re-loaded 2k server and just updated to SP4. Now I need to set a static IP. I am getting one from my linksys router right now of 103. Should I set the static to 192.168.1.5? Before I was using something like 208.201.235.2 and then setting the DHCP to 208.201.235.10-50.

after I get the Static IP asigned I have to setup DHCP. There is no special help there. it is all striaght forward.
