No, you don't absolutely need DNS for a network of this size. It would
be sufficient to mahe /etc/hosts entries on each machine, for each
machine on your LAN. Or you could use NIS, but that's more complicated
unless you know it already (but worth considering later as it
simplifies maintenance of hosts, passwds and countless other

Do you in fact have /etc/hosts entries for the peer machines ?
What does the hosts line in /etc/nsswitch.conf look like ? 
You don't perhaps have over-zealous firewalling o you machines ?
What exactly happens when you try to ping ? Does it just time out or
are there any error messages ?

What does the "ifconfig" output on 2 machines look like ? Have you
assigned the 2 NIC's on PC two to different subnets ?

I don't think you do. But ping me off-list if you like and I'll show
you my own DNS configuration. I run DNS locally in addition to NIS,
just because.

Windows Tip of the Day:

If your computer slows down for no obvious reason, this may be because
it is running short of either 1's or 0's. Files containing extra 1's
and 0's may be downloaded free of charge from the Microsoft web site
to correct this problem.
