DNS nslookup failing on DNS server

After discussion in comments, I see that you have DNS server in your IPv6 configuration. Looks like it not properly configured, so you could easily change DNS settings in IPv6 to Obtain DNS server address automatically from Use the following DNS server addresses. It should solve your issue.

    I am on one of the domain controllers and getting this issue with nslookup shown below, Why does it fail? other controllers don't have that issue. I have verified DNS config but didn't find anything wrong.

     C:\>Nslookup google.com
    Server:  UnKnown
    Address:  ::1
    
    DNS request timed out.
        timeout was 2 seconds.

    if I do same on a workstation, it works fine.

      Can you share output from ipconfig /all? Is 127.0.0.1 configured as primary and then secondary being another DC?

      @alexander-t you are probably right, but I was told that IPV6 is important and not to turn it off, but my other servers have IPV6 disabled. should I just disable it on the server too?

      you have to get rid of ::1 from your DNS client configuration (on your network card)

      @olivierg I did remove the localhost in the NIC settings, (see post for pic) is there a different place to do that. maybe reboot is required. Will reboot tonight

      Can you add 127.0.0.1 as the first DNS server and then add in additional as necessary? EDIT - Looks like things have changed since I've last setup a DNS server, loopback should be including but not as the first entry...see technet.microsoft.com/en-us/library/ff807362(v=ws.10).aspx

      @kps I have added back 127.0.0.1 as the DNS (removed it earlier) but it doesn't fix the issue with nslookup, still getting DNS request timeout.

      What server does nslookup default to? Also try doing this: (<br> nslookup <enter> set server 127.0.0.1 <enter> google.com <enter>
