You didn't explicitly list them. Can I assume that they are:
win7 192.168.1.1
fedora 192.168.1.2
xp1 192.168.1.3
router 192.168.1.254
?
Are these all DCHP assigned from the router? or static?
If dynamic, the router will also probably help set up your routing
tables as well.... (and possibly your DNS stuff as well....)

Strange! Could be firewall related....

??? xp1 can ping win7, but win7 cannot ping win7???
And win7 cannot ping fedora? I must confess, I don't know that much
about win7, but that seems strange.

Does traceroute tell you anything about the network routing?
(BTW, Microsoft spells traceroute: tracert)
Usually, if you have the proper routing, it will tell you how it
connects. My laptop connects to every machine on my LAN directly (only
1 hop), even though the laptop is connected to the router with the wlan,
and the other machines directly with the wired network.
And my network is particularly convoluted:
ISP <-> ISP wireless-router <-> linksys wireless router (2 linux servers
wired directly, third cable goes to a 4 port switch, one of which goes
to my son's XP, another goes to another switch with 2 more XP machines
and an HP printer on it). All of my linksys-wireless and the wired
connections use the same 192.168.6 network.
Microsoft has a tendency for each new OS to try and supersede the
previous wrt Microsoft networking control (netbios stuff).

631 is the CUPS printing stuff. The rest of those are Microsoft only
services. Maybe Samba (smbd/nmbd) will make use of them.
Are you running samba on your fedora machine?

If you can ping the router without them, you don't need them.

OK.

wlan0??? You didn't mention this before (but its the same as I am using
from my laptop). I have 3 XP machines on my home network, and I have no
problems pinging them (though they don't seem to respond to traceroute!)
Either way, and I have 2 linux servers (wired) that the XP machines can
ping as well as my laptop.

Have you tried the ping tests after turning off your fedora firewall
(iptables)? Are they any better or do they still fail?
What about turning off your XP firewall, just to test the pinging?
