ICS - when needed?

I setup a home network, with a D-Link router and 4 PCs behind it. Somehow,
when configuring the initial network connection on the first PC, I ended up
with ICS as well as the actual connection. Now, we don't need ICS, as I
understand it - I believe it to be used when you DON'T have a router, and
wish to connect another PC to the internet, via the "first" one, using a
second NIC in the first one.

So I am under the impression that we don't need ICS, and would like that
confirmed. If we DO, please someone tell me why - inquiring minds want to
know!, and if not, then a) does it affect anything (e.g. are ALL net "calls"
routed through the first PC?) and b) how on earth do I get rid of it! I
uinstalled a new router a couple of weeks back, with faster wireless
networking (for the PCs upstairs), and knocked out ALL the networking
settings on the first PC, in an attempt to resolve this, but STILL ended up
with ICS as well as the base connection.

Any clarifications on tha above would be extremely welcome!

Thanks

Jeremy,

The simplest way to get rid of ICS would be to un install the second NIC. ICS
can't operate without a second NIC.

Or, you could run the Network Setup Wizard a second time, and select
This computer connects to the Internet through another computer on my network or
through a residential gateway.

Chuck,

First, I should have mentioned, the PC has not nor has ever had, a second
NIC. Second, it was THAT network setup option you suggest that I used, and
that seemed to decided I wanted ICS! :-(

Jeremy,

You can only have ICS when there's a pair of NICs, or when there's an internal
modem, and a single NIC. I would gather that you are in the second case, and
now you are using the single NIC for connecting to the router.

So are you saying that ICS was activated when you ran the NSW, and intentionally
selected:
This computer connects to the Internet through another computer on my network or
through a residential gateway.

ICS is generally activated by the first option:
This computer connects directly to the Internet. The other computers on my
network connect to the Internet through this computer.

Note "The other computers on my network connect to the Internet through this
computer." Are you sure that's not what you selected?

Try deactivating the modem, then run the NSW.

Ahah! The modem, of course! And yes, am sure that I didn't use the above
option, as I did not want ICS - but ended up with it. Will follow your
instructions and let you know what happens. Sounds good - many thanks!

Chuck,
Having disable the modem, and re-booted, I went to make another network
connection, only be told that I am configured just fine for broadband, and
thus don't need one. There's no way it seems to DELETE an existing
connection, so does that mean I have to get rid of the various network
properties (protocol/clients/etc) before I can create an ICS-free connection.

By the way - many thanks for your assistance. Much appreciated

Not quite

1. Disabled modem
2. Re-booted
3. NSW
3.1 Connect to internet
3.2 Set up own connection
3.3 Broadband always on
3.4 Connection already configured - no options to make a new one

Sigh ... Internet Gateway still running on the PC as well

OK, Jeremy,

At this point, I would concur that deleting the existing connection makes the
most sense. But you say there's no option for doing that.

I wonder if this situation is of interest.

If the latter doesn't help, I would agree that un installing protocols and

start over, is the only possibility. Maybe I'd see something, if I was sitting
in front of the computer. From here, I don't.

No, you don't need ICS with a router.

What tells you that you have ICS? Does one of the network connections
have the word "Shared" in its status? If not, you don't have ICS.

Do you see an Internet Gateway icon? If so, that doesn't mean that
you have ICS. The Internet Gateway is your D-Link router, and
clicking the icon lets you enable and disable the router's Internet
connection.

Yes, my conclusions as well. Looked at the your article - I installed XP
with SP2, so that's a no-no, but wil digest that and the MS aricles in case,
before starting again from scratch. I'll let you know how I get on!

When I open up Network Connections I see

1. "Internet Gateway"
Internet connection
(Type) "Internet Gateway"
(Status) "Connected"
(Device Name) "Internet connection"


2. "LAN or High Speed Internet"
Local Area Connection
(Type) "Lan or High speed internet"
(Status) Connected, Firewall
(Device name) Broadcom etc ...

3. "VPN"
etc ....

Clicking on the Gateway Icon does NOT give me control of the router; I have
an Icon for that in My Network Places as a uPnp device, which gives me
access to a web interface to controlling the router. ICS status shown when I
click on the Gateway Icon - no mention of sharing, a box captioned "Internet
Gateway" shows "Status" (connected), Duration "4 days etc", Speed "10.0 Mbps"
(uh ? Does that slow our home network down?) and another box entitled
"Activity", with a little diagram "Internet" (Globe) linked to "Internet
Gateway" (globe and monitor) linked to "My Computer", PC & monitor, and
packets sent and received underneath). Clickon in Properties on this lists
the services on our network users can access, some weird stuff like
"BT-kylg", "DCS-3120" and then recognisable ones such as IP Sec, PPPT, and
virtual servers for such as DNS, FTP, HTTPS, POP3 etc etc.

Very strange!

Thanks for giving the additional information, Jeremy. What you see is
completely normal -- there's nothing at all strange about it. Here's
what it means:

1. ICS is not enabled on your computer. The status of your "LAN or
High Speed Internet" connection would include the word "Shared" if it
were shared.

2. The Internet Gateway icon represents your D-Link router. To
demonstrate that, disconnect your computer from the router, which will
make the Internet Gateway disappear. The Internet Gateway will
reappear when you reconnect your computer to the router.

Clicking the Internet Gateway lets you disable or enable the router's
Internet connection.

The numbers under "Internet Gateway" show how many packets your router
has sent and received. The numbers under "My Computer" show how many
packets your computer has sent and received.

The list of services on the "Properties" page shows how your router is
configured to allow unsolicited connections to your computers from
computers on the Internet. For example, if you were hosting a web
site on one of your computers, you'd enable the HTTP service.

For more information on the Internet Gateway, see the topic "Using
Internet Gateway Device Discovery and Control" in Windows XP Help and
Support.

3. The UPnP device also represents you D-Link router. It gives you
access to the router's full web interface.

4. The reported speed of 10.0 Mbps is the maximum rated speed of the
router's Ethernet output. That's much faster than any home broadband
connection speed, and it has nothing to do with the speed of your home
network.
