No Internet, good tcp/ip, good winsock, and on the network...

Posted on 2005-05-06

I have a XP Pro w/SP2 pc on the network. I reinstalled tcp/ip, winsock, and it is seeing other pc's. When I do ipconfig, all seems as should be there. The other pc's on the network get online fine. I don't know what to do next.

    Post the info from this command (you'll need a c: prompt):  ipconfig /all
    Also, what's (broadly, the overview) the network look like?? Gateway's, Router's, switches/hubs?  That kind of thing.

    Also check the Windows firewall - probably reset it to the default settings.

    First, lets test using Ping..

    Step-1: Ping Loopback IP address ( Success shows that TCP/IP is properly installed.

    Step-2: Ping local NIC's IP address. Success shows that NIC is working properly.

    Step-3: Ping Default Gateway. Success shows that local physical layer connections are ok.

    Step-4: Ping Remote IP address. Success shows that remote physical layer connections are ok.

    Also, this is primarily for P2P Lans, but may provide you with some useful steps..
    BTW:  what device are you using as your Default Gateway?  Is it a manage switch or router?  Perhaps with access control lists that could be preventing you to pass?

    Another test: from the command line, run "tracert".  If that doesn't work, then run "tracert"

    They should look something like this:  If they stop at your router, then go into your router and do a PING to IP listed above.  If it can't, then there's an issue on your Internet router to the Internet.

    Very good!  To clear the ARP cache next time, open the Command Shell and enter the following command (with the *):

    arp -d *
