    What cable did you use? Or what type of network?

    Check to see if you have the firewall is enabled on the laptop. It might not be allowing pings (ICMP).

    I am using a cross over cable that has been tested and works.

    The firewals are not inabled and now they won't ping each other at all but will connect everyone I know is stumped.

    So if you're using a cross over cable that means that you have the laptop and the PC directly connected to each other. There is no switch in between. So do this:

    Ipconfig /all

    On both of the systems and paste if you would please.

    So which method are you using to connect them? Is it directly or through a "router"? I put "router" in quotes because most cable modem or dsl routers are only routers in their functionality not typically through their LAN ports. So if you have for example a cablemodem router with 1 WAN port + 4 LAN ports then the LAN ports are really a switch and you'll need a nomal ethernet cable (not a cross over cable). If you're connecting your PC to the WAN port then indeed a cross over cable is the correct cable but I'm not sure why anyone would want to connect their PC to the WAN port as part of a home connection.

    We have tried both but the weird thing is I have connected other laptops through this cable straight and also through the router so it must be a problem with the base unit and (or) the Laptop I just don't know what

    Very strange indeed but there is nothing like a tough Monday morning challenge :) I'll await your ipconfig /all output and if you can tell me how the systems were connected when you issued the ipconfig command that'd get us started. I'm sure we'll figure it out.

    One thing that stands out is the 25.165.89.x IP you are using.
    For private use 192.168.x.x is more normal.

    Were are you getting the defailt gateway IP as this also doesn't look right.

    If you are using ICS then it too should be in the 192.168.x.x range.
    Normally this is the IP of the machine that connects to the internet (192.168.x.1)

    I no when I connect the machinet togethr it is just machine to machine and we have always used these addresses we just manualy type them in always worked till now

    Your IP addresses are public IP's that belong to a subset in UK (looked them up). Maybe you are in the UK? Anyway, you can't use those addresses reliably forever while routing out to the internet. You need to use an ICANN standard private network.

    I would reconfigure your two laptops as...

    192.168.1.1 and 192.168.1.2 with the subnet as 255.255.255.0 and retry the pings after rebooting both.

    I understand it may have always worked, but often can't control what happens upstream from your local router. Since you are apparently using a local router (or cable modem) we could only further diagnose this buy viewing it's routing table. We could then create traversal routing entries to point back to your network.

    If you think I might be way off... just remove the gateway from both computers, reboot and retry pinging each computer from the other while not connected to the internet. Reset your local switch too. Unplug the router altogether. Hope this helps...

    This site is cool, wish I found it earlier. Was looking for an answer to my air conditioner problem... :)
