DSL sharing in windows 2000

I set up a DSL (ISP:SW Bell) share on a sys configured with Win2K Pro. The client, configured with Win98SE, is able to access the shared DSL with only one problem. Sites using shockwave appear to hang. Server has no prob accessing these sites. Also,IE5 connects very slow or not at all on both systems. SW Bell only supports Netscape. Anyone have a suggestion on how to fix the problem with shockwave?
