Please help me setup Local Area Network. I cannot ping Windows XP host from Ubuntu 9

Hi, complete noob here. I need a helping hand with a Local Area Network that I am planning to put up.

Details:

Equipment:

1. CNet Network Switch
2. UTP CAT5 Ethernet Cables
3. RJ45
4. Ethernet Cards for each host

Operating Systems:

1. 2x Windows XP
2. 1x Ubuntu 9.04

Diagram:

Objective:

1. ping each host to check connectivity
a. Ubuntu ping Windows
b. Windows ping Ubuntu
c. Windows ping Windows

2. Share Files
3. Play Network Games
4. Internet Access for the 3 hosts

Yet More Details:

1. I've set all of the hardware up
2. Windows hosts can ping other Windows Hosts - NOT UBUNTU

PROBLEM:

1. CONNECTIVITY

a. Ubuntu cannot ping other Windows hosts - Therefore NO CONNECTIVITY
Since I run dual boot.
b. I have not tried pinging Ubuntu from Windows XP yet
c. When I boot into Windows I CAN PING other Windows hosts

So my problem is 1.a. I have disabled the firewall of both Host 3 (Ubuntu) and Host 2 (Windows XP). I still cannot ping.

Diagnostics:

1. ifconfig

Code:

ifconfig

2. netstat -rn

Code:

netstat -rn

3. ping IP

Code:

ping 169.254.204.222

From the output of ifconfig, it appears that the eth0 card is only running IPv6 (see line 2). The rest of your network is probably IPv4.
Unfortunately I don't know Ubuntu, so I can't help much further.
On my system I'd be looking at

/etc/sysconfig/network
/etc/sysconfig/network-scripts/ifcfg-eth0

but I'm not 100% sure that's where they are on Ubuntu.
