samba - Sep 2000 - Samba works with NT machines not 98, please help me

I am running Samba 2.0.7 for Linux and having some problems viewing the shared
directories on the Linux machine from the WIN98 machines. It keeps saying that
the 'Network is Busy' and doesn't show me any  shared folders...
However when I browse the network from an NT machine it works just fine... ??

Can anyone explain to me what's wrong?
