System Policy for Win9x operating system

I have a network with an NT4 server as the domain controller, 5 Win98, 1 WinME, 1 WinXp and 4 Win 2000prof workstations on the network. I have found it easy to apply System Policy on WinXp and Win 2000 workstations. I can’t do the same on Win98, so I need help on how I can apply the policy from the server as I did on the others
