Internet Connection Sharing Problem

[Dindo LABATITI]

I have a winxp pro machine named PC00 that is connected to the Internet via
DSL. I shared the internet connection for ten other Winxp pro computers
following the instructions on how to set up ICS on the Microsoft website.
The icon "Internet Connection on PC00" shows up on each of those computers
in Network connections window. But nothing comes up when I open up Internet
Explorer.

What services should be run in order for ICS to work?

Should anything be done on each of the computers before they can access the
web?

I hope for your response.

Have you disabled any services? If so, which services, on which
computers (host or client)?

These tests should help you 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 each 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 or your ISP's DNS server

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

ping 192.168.0.1
ping 216.239.39.99
ping google.com

4. If #1-#3 are right, enter these addresses in Internet Explorer on a
client. They should both take you to the Google web page:

http://216.239.39.99
http://google.com

Steve,

I followed your instructions on the client computers. But the problem
persists. I can ping 192.168.0.1 but not google. Aside from that , the NIC
connected to the DSL modem shows no IP address and its icon on the system
tray shows exclamation point. I have tried giving the NIC an address of
192.168.0.2 since the address is not used by any of the 10 clients. No
good.

I am at my wits' end. I'll just have to reinstall winxp and see if the
situation repeats. Thank you very much for your help.

"if at first you don't succeed, reinstall."

Most DSL connections require some sort of PPoE software running does your
require this & is it running?

I'm sorry, but I can't tell from your reply what happened when you
tried the tests that I gave.

Did your computers pass the first two tests? If not, ICS isn't set up
properly.

If they passed the first two tests, can the clients ping
216.239.39.99? If they can ping that address but can't ping
google.com, something's wrong with DNS resolution. In that case,
manually assign your ISP's DNS server on the clients.

If your DSL connection uses PPPoE, the LAN connection doesn't get an
IP address from your ISP. In that case, assigning a static IP address
to the LAN connection is fine, but it has to be in a different subnet
than ICS uses. Good values include 192.168.1.1/255.255.255.0 and
10.0.0.1/255.0.0.0.

My DSL provider does not require any software. I used to be able to give
access to all 10 computers for the past months. I had the same setup but
slowly upgraded all 10 systems to SP2 over time. Suddenly last week, I
couldn't connect. I reinstalled last night only to find out this morning
that I still have the same problem.

Steve,

I did ping the addresses to told me to. I had success only with
192.168.0.1. The other two timed out.

The NIC to the DSL modem shows an IP address outside 192.x.x.x range with
subnet mask of 255.255.0.0.

I followed the instructions in your website on freshly setting up ICS on a
new installation. Nothing doing.

Then there's this strange voluminous exchange of data on my LAN NIC. All
other PCs show activity on their NICs with the same amount of data transfer
even when there's no user on the computers. File and Printer sharing works
fine all 11 computers (including the supposed internet gateway). I noticed
at one time that this exchange stopped when I stopped the Universal Plug and
Play Device service.

What could possibly be the issue here?

Steve,

I finally got it running. A router (Linksys BEFsr41) between the PC and the
Modem solved the problem. Nothing needed to be done to the individual PCs
after all. DHCP provided by the router does it all. Thanks for your help.
Thanks to ChuckTX too.
