networking question to Allan and the other geeks...

  1. ok.. I've got WinXP pro and I just upgraded and re-formatted my pc.

    but there's a problem with setting up the lan. It worked the first day I tried it, and I could share the internet connection and get between pcs. But then it just stopped working.

    I can ping from one pc but not the other...

    Could you give a few more symptons, problems please?

    What is the exact problem. Aren't the computers showing up in Network Neighborhood?

    Are the lights on your nics lighting up?

    Are you sure you have your IP and subnet mask right?
     
  3. sorry, I should've been more specific.

    but icez is already helping me on the chat... I'll post here again and be more specific if he can't help me. :)

    Ok, I´ve tried helping The_Bass, here´s the problem:

    Computer nr.1 and computer nr.2 are connected via crossover cable. Nr.1 is connected to the internet and is sharing the connection.

    IP info for Nr.1
    IP address:192.168.0.1
    Subnet mask: 255.255.255.0

    IP info for Nr.2
    IP address 192.168.0.2
    Subnet mask: 255.255.255.0
    Default gateway: 192.168.0.1
    Primary DNS: 192.168.0.1

    Both computers are in the same domain.

    The problem is now that Nr.1 can see them both in network neighborhood.

    Nr.1 can´t ping Nr.2
    Nr.2 can ping Nr.1

    Nr.2 can´t access the internet.

    The NIC´s seem to be set up correctly, so I´m running out of solutions here. He doesn´t have a spare crossover cable for further testing. Rebootet quite often to no avail.

    I have the exact same setup here at home, except my IP addresses are 10.10.0.1/2 and mine works perfectly.

    Any ideas?

    (I bet I´m missing something quite obvious)
     
  5. thanks icez... now I don't have to write it. :)

    how are you sharing your internet connection? remember, you can't use ics if you have a nat router/hardware firewall.
     
  8. I don't have a router or anything... I just have ISDN and am sharing through the windows connection sharing thing. it worked before I formated.

    Problems with both machines -

    Never set one of the octets in a machine's IP address to zero. You'll get really unpredictable results because zero is the network address for that entire subnet.

    192.168.0.x is bad. Use 192.168.1.1/2

    It's okay in a subnet mask - but a subnet mask isn't an IP address.

    Problems with #2:

    192.168.0.1 is not a DNS server. Real DNS addresses need to go there.

    My suggestion? Get the XP box running and use make an Internet Connection Sharing floppy disk to connect the other machine.

    Is this machine using cable, DSL or dialup to access the Internet?

    It´s connected via Dial-up.

    One thing Alan, I don´t doubt you´re right, but my machines have worked fine with 10.10.0.1/2 since last march.

    And I couldn´t get internet access on my comp nr.2 until I set pointed the DNS to comp. nr.1


    Well, that´s M$ for ya.
     
  11. i'm using dialup - isdn.

    I changed to 192.168.1.1/2. it didn't change anything.

    and using a floppy didn't work either...


    btw. pc nr. 2 can't access the workgroup, but can still ping pc nr. 1.. I think I might just format again... see what that does. :(
     
  12. Workgroup names the same?
     
  13. yeah.. I don't overlook that obvious things. ;)

    Then I'd be reinstalling networking components from scratch, I guess :(
     
  19. yebb... I'll do that
     
  20. Alan is correct with the 192.168.0.x vs. 192.168.1.x

    Just not proper.

    Just a quick run through
    Try retyping the work group names
    redue the IP settings
    Make sure they both have the same DNS numbers
    Try creating a hosts file
    To trouble shoot the cards and cable install IPX
    If the machine won't see each other with that you probally have a problem with the cable or card
    Make the Internet sharing disk
    Make sure the firewall is turned off on both machines
    Make sure you have a share on both machines that doesn't end with a $
    Spend the money on a LinkSys box.

    Other than that the problem may be the Chair to Keyboard interface.
