Thanks Jag; Here is my table:

Kernel IP routing table
Destination     Gateway         Genmask         Flags Metric Ref    Use
Iface
10.3.1.10	    0.0.0.0		  255.255.255.255 UG    0      0
0 eth0
10.3.1.0        0.0.0.0         255.255.255.0   U     0      0        0
eth0
127.0.0.0       0.0.0.0         255.0.0.0       U     0      0        0
lo
0.0.0.0         10.3.1.1        0.0.0.0         UG    0      0        0
eth0

I tried to remove the 10.3.1.10 record and succeed in doing so (sort of)
with

'route -v del -net 10.3.1.10 gw 0.0.0.0 netmask 255.255.255.255'.

When I execute this and issue route -n again I see:

Kernel IP routing table
Destination     Gateway         Genmask         Flags Metric Ref    Use
Iface
10.3.1.0        0.0.0.0         255.255.255.0   U     0      0        0
eth0
127.0.0.0       0.0.0.0         255.0.0.0       U     0      0        0
lo
0.0.0.0         10.3.1.1        0.0.0.0         UG    0      0        0
eth0

But when I restart the network services with 'network restart' or reboot
the machine, the 10.3.1.10 record returns....WHY IS THAT? What can I do
to rid of it forever short of reinstalling?

Thanks,
Chris

This appears to be the problem.  You should have two routes involving
eth0.  The first one should be for the destination of 10.3.1.0 with no
gateway and set to the eth0 interface.  The second should have a
destination of 0.0.0.0 (this is the default route setting) and a gateway
of 10.3.1.1, and the interface set to eth0 of course.

The above advice assumes I'm understanding the way you formatted your
routing info.  It would help if you gave us the output of
'/sbin/route -n'
