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.

    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?
