You have to run ICS on each pc, if I remember right the wizard HT was talking about created a disk that you run on each pc? I do remebmer you have to have the second edition or later. If you have Netbeui on the clients that could prevent ICS from working. If the ICS wizard doesn't make a disk then just set the clients to obtain IP address and set WINS for DHCP and remove any previously installed gateways. Ah what the hell let me look it up.....
