Thanks Jim,
    I will try your suggestions.  Unfortunately some things have came up
here again and I have to put this on hold for a couple of days.  I have
seen the #ltsp IRC suggested in the past, but how do I join/use it?

    Also I have determined definitely which card is eth1 and which is
eth0, since they are both different brand cards right now I just checked
the network properties in the gui to see which card had which settings.
The LNE100TX is set for 192.168.0.254 to offer DHCP to the internal
network, and the Intel Pro100 is set to DHCP waiting for an IP from the
external network (I have also tried static).  I have plugged each cable
in individually and tested with ping.  Nothing I do gets me past the
NIC's.

    But just shoot me info on how to get to #ltsp IRC and I will just
jump on when I try my next attempts.
