By 'see' I mean, even though each machine can access resources on the
'net, non can connect to and access LOCAL resources, despite all being
connected through the same router. On one machine I can see a window's
network icon, but I click on it and generate a permissions error, that I
don't have sufficient permissions to access those resources. 

In suggestion I avoid Samba, are you indicating that NFS would work much
better? Samba has always, until now, worked well for me, but I am
willing to give NFS a shot. I really don't care which I use, as long as
I can enable sharing among these machines and establish remote access
and control that works too.

On my router's web admin screen, it shows machines on my LAN, even
though those machines can't talk to each other. I have uninstalled
NetworkManager, even though it was working fine.

Are these in a script, or just entered at the command prompt? I don't
mean to sound ignorant here, but I am not sure how to use these.

Is 'finnix' then a replacement for NetworkManager?
