system policy template

Hi,
I have a winnt4.o network. With mostly 95 & 98 clients. I’m setting a system policy creating my own template on the server for the clients(1st on a 95,98 machine & then copied over to the server).
My question is I don’t know the registry path to have the win95&98 machines not be a browser(not to participate at all).I would like to set the setting to no. If anybody knows the registry path. It would be greatly appreciated… Thanks
