Internet Sharing Norton Internet Security

Dear Sir/Madam,
I have windows 2000 pro installed and Norton Internet Security 2002 installed. I have another computer in the network with win 98.
I have internet connection on win 2k machine. I want to give sharing to win 98 machine.
I can see both machines in network. I can share resources.
What is with the Norton Internet Security to enable Internet Connection Sharing ?
Thanks
