Ping-tracert returns only time outs yet TCP/IP functions fine

    I have an ME system on a home net ( It's
    gateway is which is a LinSys router connected to a
    broadband cable modem. I cannot ping this machine from any other on my
    home net nor can I ping anything (local or Internet IP address) from
    this machine. Yet all browser functionality is working fine. I can put
    a sniffer on the hub to which it connects and see that TCP/IP to the
    Internet is working, connecting to a shared directory (via NetBios
    over TCP) works fine, using a net use * \\othermachine\share command.
    Yet when I attempt a tracert or ping, no ICMP packets ever appear. It
    is as though they are being blocked and never hitting the wire. I have
    been using Panda Anti-Virus Platinum 7.0 with a built-in firewall and
    thought that have been the culprit but disabling that has made no
    difference, nor has been ripping out the TCP stack completely and
    re-installing. I also replaced the original NIC with an Intel
    EtherExpress PRO card with no change in the symptoms.

    This is driving me nuts. Anyone have any suggestions or ideas for me?

  2. I'd suggest uninstalling (not disabling) the firewall.
