    Are you wireless or wired to your connection?

    Go to the Start Menu > All Programs > Accessories > Command Prompt.

    Type in the box ipconfig/all and press enter. Then right click in the box and press Select All and then press Enter on the keyboard. Come back here and press CTRL and V together in a post and it should copy what you saw.

    That shows a good connection.

    In command prompt, do the following commands:

    ping google.com
    ping 74.125.225.230
    ping 209.18.47.61
    ping 192.168.0.1


    If the first one fails, do these commands:

    nslookup
    server 8.8.8.8
    google.com


    And notate the information here.

    Autoconfiguration should have established a default nameserver. It seems that in your case it did not pick a valid one... probably the failure was when your modem connected to your ISP... that needs to be fixed, really.

    The DNS server shown on your ipconfig, 209.18.47.61 does not work for me. That might be because it is not a public nameserver that I can access, or it might be actually broken. Trying the NSLOOKUP commands you were asked to do might give us a clue.

    (typing NSLOOKUP should display your current DNS server which is probably the address mentioned above. This leaves you talking to NSLOOKUP, with a simple ">" prompt. the command "server 8.8.8.8" tells NSLOOKUP to use the google public server for subsequent commands, typing in a name like "google.com" will have it try to look up that name. TO END THE NSLOOKUP SESSION TYPE THE COMMAND "EXIT")

    If nslookup can find things after you tell it to use 8.8.8.8, then you can work around the problem by entering it as a static dns address in the internet protocol properties of your network connection:

    - open network connections
    - right click on the link you are using to get to the internet
    (local area connection or wireless network connection)
    - click "Properties"
    - in the properties window find TCP/IPv4, click to select it
    - click the "Properties" button at the bottom of that window
    - if "obtain DNS server address automatically" is NOT selected, this is the problem. Select it, OK out of everything, and reboot and things should work.
    - But if it is already selected, then something is broken upstream, so we do the bypass:
    - select "use the following DNS server addresses.
    - enter 8.8.8.8 in the preferred slot (or any other public server you prefer)
    - OK out of everything

    That should make things work, I think. If it does, then I suppose you could let it go, but you really should ask your ISP why they are setting you up with a bad DNS server.

    Interesting. The first time you tried to ping google it didn't resolve. The last time it resolved, but didn't ping. But other pings, such as to the time warner/roadrunner dns went through. (I have the same DNS server).

    Is this problem entirely confined to the one machine? Do you have other machines on the same network that are working fine?

    Since NSLOOKUP is not able to find things even when you give it a known-good server, there is no point in going to "network connections" and making a change. The problem is not a setting on your machine. It seems to be either in the router/modem, or possibly caused by corrupted code (or virus infection?) messing up the TCP/IP stack on your machine.

    Others here are more qualified than I to talk to you about fixing things, though if you have not done so please do re-boot your router. (Unplug the power, wait a minute, plug it back in.)

    Just for information you can find the network connections by bringing up the "network and sharing center" and clicking "Change adapter settings".

    You can get to the network and sharing screen many ways... click on the internet connection icon at the right of the task bar and there is a link to it, or go to control panel where it is listed, or (my favorite!) ask about DNS or TCP/IP settings in windows help and several of the results tell you how to get there and provide a link. ... Windows help is a handy way to find almost anything :)

    But as I said, there doesn't seem to be any point in changing the DNS setting, since the machine cannot access a server at all. Somehow the dns queries that nslookup sent to the default gateway on your modem did not work, and if nslookup will not work then nothing on your machine could do any better. The problem seems likely to be in the modem/router or beyond.
