  • Windows 2008:DNS:IPv6

    Hi,

    My first post goes here....

    Issue: DNS test fails in dcdiag /test:dns

    Server Details:
    2008 Enterprise : SP1
    Services installed : Active Directory, DNS, File Services

    Initially i had IPv6 enabled and then i removed it from the TCP/IP stack.

    i re-registered dc specific records using nltest.

    Still the dcdiag fails.

    I tried to ping the FQDN of the dc : it gives replies from

    Pinging DCert.recruit.local [::1] from ::1 with 32 bytes of data:
    Reply from ::1: time=4ms
    Reply from ::1: time=1ms
    Reply from ::1: time=3ms
    Reply from ::1: time<1ms

    but nslookup resolves correct ip address.

    I tried to search in DNS for the IPv6 records, there is none.
    I have also removed the IPv6 entry from etc/hosts file. still issue persists!!!!

    Thanks

    ::1 is the loopback address just like 127.0.0.1.
    This record shouldn't be registered into DNS.

    I almost don't dare to ask, but what is the IP address of the DC?

      I searched in my DNS zones, for this record, i could not find one.
      Is there any way to find where it is registered in the DNS?

        Have you tried deleting any AAAA records in the DNS zone and make sure there is a A record for your DC in there.

          How did you disable IPv6?

          By default IPv6 takes precedence over IPv4, so your ping results are normal.

          NSLOOKUP defaults to A records, again normal.

          What exactly does dcdiag say?

            Personally, I disable IPv6 on any Vista/Win2008 machine I touch. I don't see anyone actually using it, and it tends to cause some irregularities.

            If you disable it from the NIC properties it won't be totally disabled. To really get rid of it you need to make this registry change:

            Windows Registry Editor Version 5.00

            ; Disable IPv6 over all interfaces and prefer IPv4 to IPv6
            [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Servic es\Tcpip6\Parameters]
            "DisabledComponents"=dword:000000ff

                HI to ALL!

                Is there any advantage to configure and use IPv6 for DNS at Win 2008?
                If Yes, then any steps how to do it?

                Thank you.

                  exit304, the Microsoft Press training manual 70-642 covers your questions in the first couple of chapters.

                  However, the benefits are increased address space, complete inability to work with netbios (Hey, it's a benefit in my mind).
                  some of the negatives are it's a newer protocol, and not many poeple use it.
                  You can't traverse the internet if you have a full ipv6 network, without something like teredo or isatap.
