Help with DNS setup

I have tried several times and I think I am doing something wrong.
Previous post: https://www.techrepublic.com.com/5208-6239-0.html?forumID=46&threadID=162976

I have re-installed again and this is what I have done so far.
Installed w2k server. During setup I specified an IP of 192.168.1.5 and the server name is SERVER.
Added DHCP and configured it. With options 03, 06

Now I don’t know if I should setup DNS first before doing the dcpromo. I have always ran the configure your server wizard to add AD and in the wizard it adds DNS for me.
Should I do the DNS and configure it?
