    One of three machines on my home network is giving me trouble.
    All are running XP SP2.
    Call the troublesome one machine "X". It does have connectivity, can access the internet through the router. However, it cannot be seen by other machines on the network, nor can it see shares from other machines.

    Specifically, pinging from machine X:
    ping other hosts by name or IP: Yes
    ping localhost or 127.0.0.1: Yes
    ping own hostname or own IP address: No reply.

    Pinging from another machine on the network:
    ping host other than "X": Yes
    ping X by hostname or IP: No

    Everything worked at one time, don't know what caused the change.
    Any thoughts appreciated.

    Turned out to be a firewall problem. (Symantec Client Firewall)
    Needed to have 127.0.0.1 added to the trusted network IP's.
