    The hardware configuration is a router connected to a
    modem and the outside internet, and also connected to
    each of four computers by ethernet cables, so all
    computers are on the same subnet.

    Enabling WINS in smb.conf made no difference.
    Establishing an lmhosts file on a windows computer
    associating with dell allowed ping dell to
    produce the same result as ping, but
    otherwise there was no improvement.

    One more drastic test.  After becoming skeptical of
    smb.conf because no log files showed up where specified,
    I made a backup and deleted it entirely --
    rm /etc/samba/smb.conf .  On rebooting, there was no
    change, the Linux system could still read all windows
    computers, though they could not see the Linux system.
    So it seems Samba is paying no attention to smb.conf.
    Is there a way to communicate directly with Samba to
    find out what it is relying on?

    I have a Fedora 10 Linux system connected through a
    router to three windows computers (XP+XP+Vista).  The
    Linux computer seems unable to present a netbios name to
    the rest of the network.  The Linux computer can read
    files from all of the Windows computers, but the windows
    computers cannot see anything on the Linux system.

    The following diagnoses have already been made:

    I shut off the modem connecting to the internet, then
    disabled all firewalls.  No improvement.

    I looked in the router for its table of attached
    devices.  It lists a device name for the windows
    computers, a blank for the Linux computer.  The device
    name is what windows puts after \\ on a remote file
    name, and what Samba calls netbios name.

    The only communication from a windows computer that
    responds is ping .  A ping with a netbios
    name fails with the diagnostic:

        A ping request could not find host Dell.
        Please check the name and try again.
