ICS not working

[niel]

I have used the wizard to setup the PC1 (with Broadband connection) as the
host. Then I have used the same wizard to set PC2 to connect to the host.

The broadband connection is shared, under the list of network adaptor, I
choose the NIC which connect to my PC2.

So, I tried to ping PC2 from PC1, fine, PC1 to PC2, also fine. But PC2 can't
surf!

Any help? I ametting older and older for fixing this! Same thing happened to
my friend's machine too. BTW, both PCs are running WinXP Pro.

Actually, after playing around with the settings, it works. The next day
when I boot up PC2, not working anymore.

Any help out there?

These tests will help find the problem:

1. On the ICS host computer, right click the local area network
connection and click Status | Support | Details. It should show:

IP Address: 192.168.0.1
Subnet Mask: 255.255.255.0
Default Gateway: none
DNS Server = none

2. On the ICS client computer, right click the local area network
connection and click Status | Support | Details. It should show:

IP Address: 192.168.0.x (1<x<255)
Subnet Mask: 255.255.255.0
Default Gateway: 192.168.0.1
DNS Server = 192.168.0.1

3. If #1 and #2 are right, open a command prompt window on the client
and enter these lines. Each one should get four replies:

ping 192.168.0.1
ping 216.239.39.100
ping www.google.com

IP Address: 192.168.0.1

2. On the ICS client computer, right click the local area network
connection and click Status | Support | Details. It should show:

IP Address: 192.168.0.x (1<x<255)
Subnet Mask: 255.255.255.0
Default Gateway: 192.168.0.1
DNS Server = 192.168.0.1

The IP address for client computer is actually 169.254.232.5 (When I use
Automatic Configuration for IP address). If I entered 192.168.0.2 manually,
with Subnet Mask 255.255.255.0, default gateway 192.168.0.1. All IM and
browser can't connect at all too.

3. If #1 and #2 are right, open a command prompt window on the client
and enter these lines. Each one should get four replies:

ping 192.168.0.1
ping 216.239.39.100
ping www.google.com

Destination host unreachable...

Could you figure out the problem? Thanks again!

ping www.google.com

Ping request could not find host www.google.com. Please check the name and
try again.

Any idea now?

Is your DSL modem internal?
If you had an external modem, you could use a router and not mess with ICS.
This would let PC2 access the net without PC1 being turned on.

 

[niel]

I have an external modem, and I don't have a hub/switch. I use cross-over
cable to connect to PC2. PC1 has two NICs, one for the modem, another one
for PC2.

Thanks for the advice anyway.

Silly question, if you use a MODEM, why do you need an NIC for it?

 

[niel]

Because my DSL Modem requires a NIC for it, it is not an USB aDSL modem.

You can ping the local network. You can ping Google by IP address,
but not by name. That indicates a problem with DNS name resolution.

Make sure that the "DNS Client" service is running on the client
computer:

1. Right click My Computer, and click Manage.
2. Double click Services and Applications.
3. Double click Services.
4. Double click DNS Client. If the Service status is Stopped, click
Start.
5. Set the Startup type to Automatic.

Disable and re-enable the client's network connection and try again.

If it still doesn't work, try configuring the client manually, using
these settings:

IP Address: 192.168.0.2
Subnet Mask: 255.255.255.0
Default Gateway: 192.168.0.1
DNS Server = your ISP's DNS server address

If you want a simple and carefree life, and can afford a few $$ more,
toss the thing away and replace it with a proper router/switch/gateway,
which will do your firewalling, NAT, and share the internet connection
among however many PCs are plugged in to the LAN.

Not only does it save you one NIC on the ICS PC, it saves you enormous
amounts of hassle with ICS/NAT software, and it means that any PC can
access the internet without 'the ICS PC' having to be powered on (i.e.
much better redundancy if that PC happens to break).

I assume you aren't telling him to toss away his DSL modem? Without
that the router really wouldn't do any good!

I do agree though. ICS is a complete and total pain in the ass. I
used it for about a week before going out and getting my broadband
router and have NEVER looked back. They aren't that much; you can
find a decent router from between $50-$70, or less if they are on sale
or have rebates.

I thought that most of these gateway/switch devices had the DSL 'modem'
function build in to the router these days .. if not, then yep, keep the
modem you already have by all means.

Sadly they cost rather more this side of the pond - my Draytek (with
ISDN backup for the ADSL, and 4 port switch function) was ~$200+,
however still worth it compared to the hassle of ICS/NAT/DHCP/etc. on a
Windows PC.

All the broadband routers I've seen for sale here in the US are
usually able to handle both cable and DSL; no modem is provided in
them. You hook them up between the broadband modem and your computer
(via ethernet or USB).

Ah, that's maybe why they are $70, and I'm paying 3x that - my
router/switch has the ADSL modem built in, just attach phone line(s).
