none
nslookup - default server is unknown (IPv6)

    Question

  • Hi,

    I'm migrating from an SBS2003. I'm at the stage where I'm verifying the dcdiag for errors prior to migrating all the Exchange mailboxes.

    I have a few errors to resolve as shown in my dcdiag. However, before getting to that, I want to fix what appears to be a simpler problem.

    When I do an nslookup on this newly setup SBS2011 (still in migration mode), I get:

    C:\>nslookup
    Default Server:  UnKnown
    Address:  fe80::ff60:xxxx

    Note that when I ping -a fe80::ff60:xxxx, I do get a response back with the servername.domain.local.

    DHCP has a configured scope for IPv4 but not for IPv6.

    Any guidance will be greatly appreciated.

    Thanks

  • Could it be that the DNS on the new server is pointing to something other than itself? e.g. pointing to the SBS2003 box, which is not IPv6-capable ?

  • No.

    It's pointing to itself. It seems the preference is to the IPv6 IP of itself

  • Hi GregEh,

    Thanks for posting here.

    >Address:  fe80::ff60:xxxx

    So have we also created a reverse lookup zone and added AAA record for this IPv6 address on this server ? would we still get proper result in the end by using nslookup ?

    We may first check our current network settings on this destination SBS 2011 server and correct it by running fix my network wizard:
