DNS nslookup failing on DNS server
8,114
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. DNS request timed out. timeout was 2 seconds. *** Request to UnKnown timed-out C:\>ping google.com Pinging google.com [172.217.3.206] with 32 bytes of data: Reply from 172.217.3.206: bytes=32 time=17ms TTL=56 Reply from 172.217.3.206: bytes=32 time=16ms TTL=56 Reply from 172.217.3.206: bytes=32 time=19ms TTL=56 Reply from 172.217.3.206: bytes=32 time=16ms TTL=56 Ping statistics for 172.217.3.206: Packets: Sent = 4, Received = 4, Lost = 0 (0% loss), Approximate round trip times in milli-seconds: Minimum = 16ms, Maximum = 19ms, Average = 17ms
if I do same on a workstation, it works fine.

nGX about 7 yearsCan you share output from ipconfig /all? Is 127.0.0.1 configured as primary and then secondary being another DC?

Alexander Tolkachev about 7 yearsnslookup trying to resolve domain on IPv6 address. Your DNS-server lister on IPv6 interface?
-
nickmcs about 7 years@kps Added output of ipconfig /all
-
nickmcs about 7 years@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?

olivierg about 7 yearsyou have to get rid of ::1 from your DNS client configuration (on your network card)
-
nickmcs about 7 years@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

nGX about 7 yearsCan 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

nickmcs about 7 years@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.
