    Can you copy and paste an example of an nslookup result showing us the
    errors or non-resolution you are seeing? That will better help us to help
    you. I believe I asked that before, but I did not see a reply. Try the

    (please post your results)
    (please post your results)

    Then try it with the following 'set vc' switch:

    set vc
    (please post the results)
    (please post your results)

    Also, is there a firewall rule running on all machines and the DC to stop
    pings (ICMP echo) from working, as well as DNS queries (UDP or TCP 53)?

    Looking forward to your results. If you have more tests that I didn';t
    mention, please post them too!

    Thank you,

    I demoted to workgroup and re-install the AD & DNS server, I change the Ip to to see it will work or not, it did not.

    Here is the NSLOOKUP from Server

    Default Server:

    *** can't find netserver: Non-existent domain

    You demoted your domain controller? Why?

    Try it with:
    If that worked, then it's telling me that the search suffix on the machine
    you are running this is not, or it has been changed, or the record
    'netserver' does not exist in the DNS zone under the search suffix domain
    name the machine you are running this on is set to.

    For example, from my own workstation, which has a different search suffix
    than my domain, I tried to look up a name called 'bob' on my machine:

    *** can't find bob: Non-existent domain

    This means that 'bob' does not exist under the zone the search suffix on my
    machine is set to, which is ''

    However, when I did an nslookup for (using the full FQDN),
    it gave me a proper response.

    Can you post your new ipconfig /all, please?

  4. Read inline please.

    Put nslookup in verbose mode and repost the results.
