Getting default server Unknown after configuring DNS by nslookup - dns

I am new to windows server. I just installed DNS on windows 2012 server. Here is how it appeared after installing
Then i went to DNS manager. I created a new Forward Primary zone and reverse zone. Here is the screen shot
Then i created the record (A, MX, CNAME). Here are the screen shots of each
SOA:
Name Server:
A Record:
MX Record:
CNAME:
Reverse lookup Zone:
After all that when i do nslookup, then i get Default Server: Unknown. Why ? Why i am getting unknown server
Why i am getting unknown ?
Thanks

You did all correct, but you dont mentioned are you restart DNS service after that? After restart its working fine for me.

From the quick google research it seems to be a reverse PTR record issue. Try recreating the PTR record. Here is a NSLookup Unknown troubleshooting for a bit older version. This might work for Server 2012 as well.

DNS CNAME pushed from somewhere

i have a mail server behind CloudFlare and when i check some logs and other DNS tools i seen a MX dc-abefc4aaxxxxx that isn't registered in my dns configuration in cloudflare. I tryed checking SOA and always shows cloudflare's name servers.
How can i really see where is this register being pushed?
Finally i solved this issue. Ocurrs when A record to Mail server is proxied and MX not. To solve this unproxy A record.
Here is the solution

Cannot access locally hosted sites

I have several sites on hosted on my local iis that I cannot access all of sudden.
Error I'm getting in all browsers I have installed (Chrome, IE, Edge) is- server DNS address could not be found.
Last thing I was doing before things wend wrong- installing Web Deploy 3.5, but uninstall did not help.
I checked hosts file and bindings in iis- both are valid.
Another thing I've tried with no luck:
Reset WINSOCK entries to installation defaults : netsh winsock reset catalog
Reset TCP/IP stack to installation defaults : netsh int ip reset reset.log
Flush DNS resolver cache : ipconfig /flushdns
Renew DNS client registration and refresh DHCP leases : ipconfig /registerdns
Flush routing table : route /f (reboot required)
Ping cannot file host as well
Ping request could not find host XXX. Please check the name and try again.
At the same time htt://localhost shows Default Web site with IIS welcome page.
This appeared to be a problem with permissions on host file- somehow those got broken

vps nameserver setup not working

I am a noob in the VPS-DNS world.
I purchased a VPS (with one ip) and logged into WHM to setup for production. I configured nameservers to "ns1.a-domain-i-have.com" and "ns2.a-domain-i-have.com".
Then logged into that domain account at my register where I
- set default nameservers from the registrar
- in DNS manager I set ns1, A , my server IP and ns2, A, the same server IP
After creating a host account in WHM using "another-domain-I-have.com", I registered "ns1.a-domain-i-have.com" and "ns2.a-domain-i-have.com" in the custom nameservers.
But my new website refuse to work/ nothing works, I did all these based on the understanding of tutorials I googled.
I have tried
- reinstalled the VPS
- used the default nameserver that came with the VPS host. Although, this nameserver ip is unknown.
- update cPanel
I need some help!
I already got it. It works now. The steps I mentioned aboved did it. Maybe am supposed to take this down but I'll leave it for newbies like me.

Domain transfered to OVH but DNS Host is still on 1and1

I've transfered a domain from 1and1.com to OVH, now I need to manage my DNS to point them to a new server, but running this command from here
command line> nslookup
> set querytype=soa
> mydomain.com
I found out that DNS are still managed from 1and1.
Reading the OVH guide about DNS i found out that i need to activate DNS zone from my manager. But... won't this conflict with the DNS declared on 1and1?
I'm not sure about how is this working, so does someone knows the right workflow to do this?
Thanks in advance
after a call with OVH Support the correct workflow is:
Create or configure the DNS zone
Change the DNS Server to the OVH server
in 24 hours all should work fine, I'll let you know...

Plesk Nameserver Not Resolving

I have a VPS from myhosting.com with Plesk 11. I've set up dns in windows plenty of times but for the life of me I can't seem to get this working through Plesk. Here are my settings through Plesk and Godaddy... I asked myhosting about the setup and they said as far as they can see it seems correct but for the life of me the site will not resolve... Any help would be much appreciated!!
Plesk:
GoDaddy Host Names:
GoDaddy Nameserver Settings:
Enter your domain name here http://who.godaddy.com/ and in results:
Check "status" - should be ACTIVE
Check "Name Servers" it should be ns1.v...v.com, ns2.v...v.com
Check that ns1.v...v.com or ns2.v...v.com can be resolved by command:
nslookup ns1.v...v.com
I suppose that it will be NOT resolved because your NS servers are placed in zone which can be resolved yet.
The easiest way is to use some another DNS servers, maybe GoDaddy or some other DNS hoster.
Or you can make a trick:
change domain's DNS servers to GoDaddy DNS servers
In GoDaddy's domain management panel add in DNS zone records with: ns1.v...v.com, ns2.v...v.com
Wait until you can resolve ns1.v...v.com and ns2.v...v.com - it's about 24 hours.
Switch domain's DNS server back to ns1.v...v.com and ns2.v...v.com.
Wait until changes will be visible by other DNS servers like Google:
nslookup ns1.v...v.com 8.8.8.8
All should works now.
