    The challenge got me going.
    Followed your excellent instructions. Got very excited because your
    commands all worked with no errors. But the ping timed out and failed.
    I think I know where I went wrong:

    The mac address is correct. But maybe when this device was setup in my
    previous network it had been changed from its default factory ip to the
    network it used to be on which I no longer recall. Anyway to find out?

    In case this helps:

  3. It's not necessary to login/logout of an admin account every time you
    need to do something that requires admin privledges. Try it this way:

    "Start a Command Prompt as an Administrator"
    <http://technet.microsoft.com/en-us/library/cc947813(v=ws.10).aspx>

    I just COPY the CMD icon buried in the Accessories group to the
    desktop. I then edit the properties so that it always runs as
    administrator, and change the name so I have a clue as to what it
    does.

    The current TCP/IP address of the unknown device doesn't matter,
    as that's the whole point of this entire exercise.

    What is the MAC of the print server ?
    guessing the 00-00-b4-d4-75-69 ??
    Seems weird, as the first 00-00 should NOT be zeros,
    as these numbers are uniquely assigned to the mfg of the hardware interface.

    This is a very weird ARP listing for a simple home network...

    What are the 224.x.x network devices ?
    and the 239.x.x device ?

    Never mind on these 224.x.x thru 239.x.x

    - forgot - it's Multicast - ignore them -

    --
    The "classful" IP addressing scheme sets aside a full one-sixteenth of the
    address space for multicast addresses: Class D. Multicast addresses are
    identified by the pattern "1110" in the first four bits, which corresponds
    to a first octet of 224 to 239. So, the full range of multicast addresses is
    from 224.0.0.0 to 239.255.255.255. Since multicast addresses represent a
    group of IP devices (sometimes called a host group) they can only be used as
    the destination of a datagram; never the source.

    BTW - the print server of course must be physically connected to the network
    and turned on for the PING to find it and send a packet to it...

    Any LED lights should also be on, and blinking with network activity.

    I guess I am doing something wrong or maybe the device has gone bad even
    though its led lights work fine.

    Here's what I did:

    - device is connected to the HP printer's ancient centrionic port.
    - ethernet cable from device to port on my Netgear router WNDR3700v4
    (That's the way it was working in the previous system)
    - device leds working

    - turned off my windows firewall

    - opened cmd prompt "run as administrator" privileges.
    the mac printed on the device is 00-00-b4-d4-75-69

    Next in the admin cmd prompt:
    arp -a
    arp -s 10.0.0.25 00-00-b4-d4-75-69

    arp -a
    ping 10.0.0.25

    Results are below.

    ROUTER:
    I also looked in my router settings to see if I had previously set MC
    access restrictions. Did not find anything but did not find a screen
    where they would be.

    The wan is WPA2-PSK (AES) protected. Maybe that is the problem?

    The router interface has a screen for "attached devices", both wired and
    wireless. The wired device section shows no attached devices. The
    wireless one does not include the print server.

    LAN setup shows (see attachment)

    WAN setup screen has
    unselected:
    Respond to Ping on internet port Could that be the problem?
    NAT Filtering is "secured"
