Thanks for the tips I'll take a look and let you know.
As for the redundant protocols, I unchecked those (did *not* uninstall them)
after trying everything else.
(I should explain that this is not my laptop. It belongs to a very good
friend of ours here on a visit who normally resides in your neck of the
woods, but a bit further south - in San Deigo [don't worry I shan't send him
round to your place when he returns] but I don't know the full history of his
machine. If all else fails, he'll have to do a system rebuild when he gets
home, but he is rather desparate to get internet connectivity back before he
leaves us on the next stage of his journey round Europe.)
Best regards
Mike

XP laptop ("badcomputer") has the following symptoms:

Goodcomputers CAN ping each other (IPs) Goodcomputers CAN'T ping Badcomputer
(IP)
Background:
Badcomputer went wrong after Norton was used to remove "6 Trojans" which
were all in PCODEC folder and all part of the same problem I suppose.
Behaviour is identical whether connected to my wireless home network or
neighbour's unsecured wireless network or via an ethernet cable or using a
plug in wireless card (although I have replaced drivers for all relevant
hardware). I get an excellent connection in all permutations, but neither IE
nor Firefox can be persuaded to use the "excellent connection".
Have run network wizard several times.
Have tried setting IP addresses manually to no avail.
Have run several regfix programmes and not found anything seriously amiss.
Have tried switchig off firewalls to no avail.
Have tried swearing at Badcomputer to no avail.
Any suggestions gratefully received.
Mike
Mike,
Eliminating the obvious first, swearing at the computer won't work. I know from
experience. ;(
Asymmetrical ping would generally be a personal firewall problem - and
"switching off" (which?) firewalls isn't always productive.

Having happened after you removed malware ("6 Trojans"), I'd bet LSP / Winsock
corruption though.

Dear Chuck
Thanks very much for the response. Unfortunately though, I have followed all
the steps, at the link you kindly provided, to the letter but still have
exactly the same behaviour.
Best regards

For what it's worth, winsock catalog is:
<SNIP Winsock enumeration>
Mike,
What is the actual problem? Ping makes a good diagnostic, but maybe looking at
another symptom will tell us something.
And I see IPX/SPX (NwlnkNb) in the enumeration. Do you use IPX/SPX?

http://nitecruzr.blogspot.com/2005/05/fix-network-problems-but-clean-up.html
And did you use the Cerelli registry based fix (Step 8)?
Dear Chuck
you aked: "What is the actual problem?" Well the real problem is that I
can't connect to the internet using IE or Firefox and I can't connect to
shared resources on my network (although I don't actually need to share any
resources, but I take this as a sign that something is wrong). Actually, I
get an "excellent" connection which ever way I connect and which ever network
I connect to, but the computer refuses to use that connection to communicate
with the outside world.
As for IPX/SPX, I've unchecked this and all other superfluous protocols
since I last posted (using your blog as a guide) but this has not improved
matters in any way.
I did try step 8 (and all the other steps you recommended) but none of them
helped. I'm completely mystified.
Regards
Mike
Mike,
Did you uncheck IPX/SPX? Or actually un install it? Before, or after, your
problems started? Before, or after, you ran the LSP / Winsock repairs?
The thing about LSP / Winsock problems is that we are constantly learning about
the problem. I'm currently looking for a way to actually translate the content
of the enumeration (such as what you provided) into an actual diagnosis.
Something more than "there's IPX / SPX - get rid of that"!.
As to your existing problems, let's look at them.
Have you looked at DNS and MTU, for the Internet symptoms?
