Internet Connection Sharing

Hi
i am running w2k server and i am trying to get internet connection sharing working.
I did have it working but since rebuilding both machines (w2k and 98se), i cannot get it working again.
I have DNS setup so i can PING on either machine with both IP add and Machine Name and it works…so DNS is working.
The 98 machine is being assigned an IP add by the DHCP on w2k…that is working other wise i would not be able to access the network.
i have obviously got ICS enabled on the connection on the w2k machine……so has any one got any ideas on what else to check (yes i am using 192.168.0.1 on the server and the 98 machine is being assigned 192.168.0.2)

help…..
