IP v4 duplicate

    Discuţie generală

  • Hi, We are installing and deploying windows server 2008 in a DMZ, when we finish to configure the server into the LAN, we change the static IP (v4) to another IP from the network segment of the DMZ, but when we want to stablish communications via name or IP we cant communicate, when run the ipconfig/all command we receive the following information:

  • Hi,

    You can try the following steps.

    - netsh interface ipv4 reset (It may ask for a reboot, but you can also do that after the next step)

    - netsh interface ip set address name "Local Area Connection 2" static newIP netmask gateway

    - For rebooting you can use "shutdown -r -t 0" { 0 will make the system go for immediate reboot; you might want to change this value as per your convenience).

    Thanks,

    Girish

  • Hi,

    If you are not using IPv6 in your local infrastructure, can you try disabling TUNNEL ISATAP adapter and see if it resolves the issue.

    From an elevated prompt (run cmd.exe as administrator) and give the following command:

    "netsh interface isatap set state disabled"

    Thanks,

  • Hi Raulito,

    Thanks for posting here.

    Try the workaround in the thread below and see if the APIPA address will be gone:
