Hello everyone
I can't find ping in my 'Services' control panel applet. Can I at all
switch it off ?

Beg your pardon? Ping is a command line utility and it will not be
displayed in control panel. In fact: None of the command line
utilities will show up there.
What do you want to switch off?

apperently there is also a ping server (which responds if you try to do
ping 127.0.0.1)
I want to switch it off because I ran the Norton computer scan and they
recommend to shut down all ports. Since I don't have a firewall another
way to do it should be to just switch off the server.
Does all that make some sense to you ?

Norton are full of rubbish if they are telling you to shut off a port to
block pings. See if their firewall allows you to block ICMP traffic to
control this, though what it gains you I'm not sure.

"Ping server" is not a common description.
Ping is a tool for testing ICMP (internet control message protocol).
This is the first test tool I use if something is going wrong
(connection loss). I use "ping <ip-address> to look if the basic
network functions are up and running. If <ip-address> is pointing to
an internet address it will show me if my devices (and the devices of
the provider) are working like intended. If "Ping 127.0.0.1" doesn't
work (127.0.0.1 is the machine's internal address (so called
"localhost")) then something is awful wrong with the IP stack, the
NIC, the routing table or some other thing on very low connection
level (network layers 1 or 2).
Each host - if configured by defaults - has to answer an ICMP package.
This has nothing to do with PING.EXE, this is standard protocol stack
implementation. There is no use deleting PING.EXE because your host
will still answer to ICMP packets.
You will not be able to shutdown ports without a firewall.
The only firewall known to be absolutely secure, stable and
indestructable is shown here:
http://www.ranum.com/security/computer_security/papers/a1-firewall/index.html
Ever heard of something like "fli4l" or "ipcop"? Those are small
firewall implementations for free. Fli4L requires an old computer (486
or up, 16 MB or up).
Maybe you heard about so called "personal firewall" which will run on
the same computer you are trying to use on the internet.
I cannot recommend those firewalls for some reasons.
Here is a list with some links.

Security on the internet is a myth. You will be able to avoid some of
the "default" leaks but you have to live with a compromise between
absolute security (a1-firewall) and an open network.

Hi,
Very interesting. Certainly relevant if you have a office network to protect
but for a standalone "home" or "sole business" setup its rather less
important to filter ICMP.

Agreed.
