First place to look is your Windows SP2 Firewall settings, which may have
been changed in the Norton update. The firewall is designed to prevent
uninvited signals (such as a ping!) from coming in.

This makes logical sense to me because, when you ping the Linux server from
the laptop, the server's response is an invited one, but the server's ping
comes to the laptop unannounced and would be rejected by the firewall.

You can make an exception for your server in the firewall settings.

Win XP service pack 2's wonderful firewall? Zonealarm if you are running
that doesn't have the Linux machine as a host in the trusted zone. Norton
or other firewall installed doing the same?

Remove yourself from the Internet

Disable anything/everything to do with firewalls on both machines and see if
it then works.

Just because you can't ping doesn't mean other services aren't available.
If all services have stopped such as being able to browse the XP box over
the network then suspect either the add on firewall or wonderful MS firewall
behaving like junk. If you have a firewall running on the Linux box then
stop that running too. Always start testing from the position of nothing to
cause obstructions on either side. Re-implement in stages so you can
determine what is causing the issue.

Also need the output of ipconfig /all on the MS box - start menu, run -
type in cmd and hit enter, ipconfig/all, half information isn't always what
is required.

Well, here we go. The new Norton version includes some "internet worm
blocking" feature, which is a firewall driver without much you can change
there. You need to purchase the full internet security product to get a
configurable (and lan-aware) firewall.
Probably you wull have to uninstall all of norton, especially all the sym*
drivers, to regain control of your xp lap.
Or linux, if there is a chance it works with your wlan chips.

Thanks to everyone who replied!

It was the Firewall settings - I enabled all of the ICMP options and it
worked!

Thanks again
