    I have a PC (SUN W2100z) with a Broadcom NetXtreme Gigabit
    Ethernet adapter. The Gigabit Ethernet adapter is integrated in the
    mother board.

    I set up a LAN connection and manually specify the IPv4
    address, netmask, and default gateway of the Ethernet
    adapter (Local Area Connection).

    I can not ping to the IPv4 default gateway. I have the following
    ping XX.XX.XX.XX
    PING: transmit failed, error code 1232.
    PING: transmit failed, error code 1232.

    I CAN perfectly ping to the IPv6 default gateway.

    The only way for me to fix the problem is by disabling and
    enabling the "Local Area Connection". After that, IPv4 will
    work perfectly until the next reboot. Again, after rebooting I will
    have to disabling and enabling the Local Area Connection
    to have IPv4 connection.

    Do you know how can I fix this problem????

    Thank you very much for your answer.

    Have you checked for Adaptor Driver up dates at theMOBO's or manufacturer's

    Also, have you tried disabling the TCP/IPv6 in theProperties of your Network
    It is not necessary to use the v6; v4 is quite enough.
    The change to v6 is only to increase the number of world-wide IP addresses

    I finally found the problem.
    Thank you Mick.

    Here is the problem and the solution.

    There is a difference between the Windows XP gratuitous ARP and the
    one that Windows Vista sends. On the same computer, I also installed
    Windows XP on another partition. Windows XP can get the IPv4 address
    perfectly, while Windows Vista can not.

    All happened when I restart the computer. Windows XP sends a
    Gratuitous ARP request and does not received any response. So Windows
    can take the statically assigned IPv4 address.

    Windows Vista also sends a Gratuitous ARP request (it is different
    from the one that sends Windows XP). For some strange reason, some
    devices on the network answer to the Gratuitous ARP request even If
    do not owned the IPv4 address. So Windows Vista can not use the
    assigned address.

    The big problem is that Windows Vista does not show any duplicate
    error message on your screen. The only way to see the problem is by
    "ipconfig" command and notice that no IPv4 address is assigned to the
    Local Area Connection even if it is statically specified and the other
    of the network do not have the statically assigned address.

    I could fix the problem by disabling Gratuitous ARP on Vista:

    1: Go to "regedit"
    2: Find HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip
    3: Double-click the ArpRetryCount value, type 0, and then click OK.
    If it does not exist create of type REG_DWORD.
    4: Reboot the machine
    5: IPv4 should work.

    I hop this can help.
