ICS Problem with DSL

[erwincap]

---

I have ICS on my network (Win XP pro with SP2) connected as such

DSL ----> Modem ---> Host PC (server) ----> Ethernet switch ---> client PC 1 Desktop (win XP pro)
---> Client PC 2 Laptop (Winxp Pro)


The main machine (Host PC) and Client PC 1 (desktop PC) can reach all websites okay but client PC 2 machines can't.
E.G. They can reach yahoo, google, istorya etc but not microsoft.com,msn, hotmail.

If i connect Client PC2 (laptop) directly to the modem no problems.

I tried to reformat client PC 2 (laptop) fresh install with updated drivers, but still the same problem.

The basic setup must be okay for the clients to be able to reach any sites at all so what is stopping them reaching ALL sites.

I have tried disabling the firewall completely but this makes no diference, I have tried tweaking every setting I can think of to no avail and I have tried using specific IP addresses rather than automatically assigned ones but this didn't work either,

Does anyone have any ideas please ?

Problem solved. I did some configuration settings.

cud you tell us how you did it? had the same prob before

[erwincap]

actually the problem was in the mtu of the network card host, it was set at (576) while the client network card was set at 1500. So what i did i changed the mtu of the host to 1500 to match the mtu of the client network card and voila... everything was ok....

How do I get internet connection sharing working over a network?

1. Here's an easy way. Go to the computer which will be connecting to the internet.
Win9x: Go to add/remove programs in control panel, windows setup, and install internet connection sharing from the network section.
WinXP: Go to control panel, network connections, right click the internet connection, and click properties. Go to advanced, and enable internet connection sharing.

2. Make sure the network is setup with TCP/IP. Still on the host PC.
Win9x: Go to control panel, network, properties of the network's TCP/IP (should have the name of your network card next to it)
WinXP: Go to control panel, network connections, properties of the LAN connection.
Make sure the IP number is set to 192.168.0.1, and the subnet mask is 255.255.255.0

3. Go to the same TCP/IP section as above with the other computers on the network. Set the IP addresses to something different each time (192.168.0.[something else]), but the subnet mask is always 255.255.255.0

Then, staying in the TCP/IP properties, set the default gateway and DNS server to the IP of the HOST computer (make sure you click add in Win9x to add the IP to the list). Do not do this step with the HOST computer.

4. Connect to the net. Make sure Internet Explorer is set to automatically detect settings (Go to tools, internet options, connections, LAN settings).

5. Leach away! Same sort of thing with ADSL (provided it's not plugged directly into a hub), and make sure you set these options in the LAN network card settings, not the card the ADSL modem plugs into!

Actually same thing here although i did not manually type the IPs and GAteways for both PCs... automatically obtian IP addresses.. works like a charm, by the way when do we use this manual stuff? if things dont work automatically right?

erwin cap:
bro pwede ba ilisdan nako ang ip address sa host computer nga 192.168.0.1 ug lain nga ip ? ex: 192.168.0.37. kay naa na man gud existing server diri nga ip 192.168.0.1 unya duha man among internet connection diri office globe ug pldt man. pwede ba duha ang internet server unya thesame lan ra man. dili ba mo conflict? para back up lng ba kung magyagaw ang usa ka internet connection. wndows xp pro akong os bro.

pwede kaayu na as long as same sila first three.. so pwede bisag unsa basta ani ang start: 192.168.0.X where X is any number from 1 to 255 basta walay duplicate IP
