Just things to look for:
Do your Client PC's have there Primary DNS IP set to your Win 2003 Server? SHOULD BE
Does your Win 2003 Server have it's Primary DNS Server set to it's self? SHOULD BE
Do you have File and Printing intalled  and set in your Exception list of your FireWalls? SHOULD BE

it is because of firewall and Lazarus 2nd soul is also ok,

check them, and let us know, better you will provide your network config so we will figure out where you made a mistake.

pinging is only requied to check connectitvity of your computer. If the other services are working fine with out any trouble so you don't have to worry about it. Another thing is that which programe you are using to share your internet amoung your clients may that programe stopped the pinging because of security.
