    Ok here's my set up:

    I have pc 1 and pc 2.

    pc 1 is connected to the internet (via modem) and has two ethernet cards.
    pc 2 is connected to the crossover cable which connects into the 2nd ethernet card on pc 1

    Both computers and all the connections are configured for:
    Client for Microsoft
    Internet Protocol
    Printer and File Sharing
    and Qos Scheduling

    pc 1 connection 1 is the internet (modem)
    pc 1 connection 2 is the crossover cable
    pc 2 connection 3 is the crossover cable

    connection 1 is set up for Internet Sharing and obtain addresses automatically
    connection 2 is set up for
    connection 3 is set up for obtain addresses automatically

    My internet works fine on pc 1 up until the point where I enable "Internet Sharing."
    As soon as an ip adress is obtained for the 2nd connection (crossover connection) the internet stops working on pc 1. (pc 2 never has had the internet work on it).

    Whats funny is that on pc 2, all the files are shared and pc 1 shows up as an "Internet Gateway" and connected at 100kb/s. So the file sharing works, but the internet does not work when I try to share it.

    Another funny thing is that before I set up any of the connections if I open a website and go to google, after I set up ICS, I can search anything on google and it still works. But if I try and go to another page or another website aside from google, it doesn't work.

    I have tried using many different set up guides to setting up my connection, but none have been so far with internet sharing. I have even restarted my computer through out the steps and that hasn't worked either. Oh and by the way. I have a router, but it turns off every hour (i think it overheats) [it's a D-link Model: DI 524], and that is why I'm trying to use crossover connection because I want something more reliable that doesn't cost anything.

    Any suggestions would greatly be appreciated :)

    I used to have this kind of network.
    Manually set up the IP addresses first. Set computer one (with internet) to and subnet
    Then on PC2,, subnet and default gateway and DNS server to

    See how that works out.

    Also turn off NetBeui - it's not used anymore, and will create unnecessary network traffic.

    First Name:
    If your modem is a modem/router combo with LAN subnet 192.168.0.x you will not be able to use ICS ('cause you'll get what you described above) until/unless you change the router to another subnet; e.g., 192.168.1.x.

    If this is what you have, buy an inexpensive switch and ditch ICS.

    Thanks everyone. I ended up just buying a new router, its a linksys, so hopefully it will work better.
