Cannot ping network PCs

[Andy Baker]

We have a simple network running Small Business Server 2003 and with 3 XP
SP2 PCs connected to it. There is also a wireless access point to enable a
wireless CE device to access the network. The device can connect to the WAP
and I can ping the WAP (IP Address 192.168.1.1) and the server (192.168.1.2)
from the device successfully. The problem is that I cannot ping any of the 3
XP PCs. My first thought was that it was something to do with Windows
Firewall, so I tried to disable it. At first it wouldn't let me because it
said settings were controlled by Group Policy, but eventually I found the
Group Policy Settings for Windows Firewall and disabled it. On the XP PC the
connection no longer says 'Firewalled' but I have no Advanced Tab so I am
not really sure if I have done it correctly. What I would like to do is
disable the group settings and control the firewall from the XP PC (or
install a different firewall to the XP one.) However, it has not helped
because I still cannot ping the networked PCs.
My 2 questions are 1) Have I disabled the firewall correctly? (once I
have proved it is the firewall I will re-enable it and set it up properly)
and 2) If it is not the firewall, what else could it be? Thanks for any help
in advance.

Can all XP computers ping each other? Or post back the result of ipconfig
/all.

Yes, all the XP computers can ping each other. I think it is something to do
with the wireless filters on my wireless access point. The default setting
allows traffic to the access point and to the upstream device, which I think
is the server in my case, which is what is happening. I then need to allow
access either by IP address or MAC address to the other stations , but am
having some trouble working out the syntax for this. Hopefully I'll get
there eventually....
