Nameserver not resolving for 1 domain
Hi All,
I have a situation where my nameservers set at my VPS CPanel are working for all accounts pointing to it with the exception of one.
What could be the possible problems associated with only 1 of 8 accounts not resolving when it is set exactly like the others.
I have disabled cPHulk Brute Force Protection to eliminate that as a problem for blocking the domain, yet still nothing.
Any help would be appreciated.
Thanks.

Is the domain configured correctly on the VPS?
What is the output of
dig @localhost domain.com
Did it return the nameservers correctly?

How do I Flush CSF? I'm new at this?
The domain is configured properly, it was functioning up until yesterday.
When I run intodns I am all red flagged but not sure why. All my other domains set exactly the same way are working fine.
How is dig @localhost domain.com run?
Thanks

Use the command,
csf -x to flush csf firewall.
dig @localhost domain.com
Run this from the server shell if you have shell access, you need to be root to run this command successfully.
Can you please paste the domain name here so that we will be able to help you.

I tried to run csf -x and got the following,
csf and lfd have been disabled
The domain with a problem is advisuals.com
I ran dig @localhost advisuals.com and got the following;
; <<>> DiG 9.7.3-P3-RedHat-9.7.3-8.P3.el6_2.2 <<>> @localhost advisuals.com
; (2 servers found)

The nameservers are working because there are several other domains currently running using the same nameservers such as;
vitalchild.com
figww.com and others
Thanks

The most common reasons are
1. the domain has expired
2. the nameservers on the domain are incorrect
3. the nameservers arent registered
In your case, the nameservers aren't returning a result, and the nameservers are on the same domain
- have you got multiple zones for the domain ?
- is one missing an a record ?
edit the zone, save it, restart named, test againRob Golding Astutium Ltd - UK based ICANN Accredited Domain Registrar - proud to accept BitCoins

The dig command is not showing a valid output. Something is wrong in the server configuartion, check the zone file of the domain advisuals.com in the server. I could see errors in http://intodns.com/advisuals.com indicating the same.
What does
dig NS@localhost advisuals.com
from server shell gives?

Hi,
I could see that your server is not responding to with A address of advisuals.com. This must be an issue with the DNS zone of advisuals.com, check the DNS zone syntax, and try to save the DNS zone from WHM>DNS Zone Editor.
To check syntax frm backend use
named-checkzone advisuals. com /var/named/advisuals. com.db
--------
advisuals. com. 172800 IN NS ns1.advisuals. com.
advisuals. com. 172800 IN NS ns2.advisuals. com.
;; Received 99 bytes from 192.26.92.30#53(c.gtld-servers. net) in 4391 ms
;; Received 31 bytes from 173.208.240.204#53(ns1.advisuals. com) in 1546 ms

You have A records set up for ns1.advisuals.com and ns2.advisuals.com but not for advisuals.com itself.

There is an A record set-up advisuals.com
I have attached a copy of the DNS settings at the server.
Please have a look and suggest.
The nameservers are set correctly because as previously mentioned there are sites currently set to those names servers such as;
vitalchild.com
figww.com and others

The domain name isn't propagating:
nslookup advisuals.com strawb.mit.edu
Server: strawb.mit.edu
Address: 18.71.0.151#53
** server can't find advisuals.com: SERVFAIL
Increment the serial number by one, then save the zone record again.

I have incremented up twice already trying to get it to propagate, and still having the same issue.

Did you try adding
ns1 IN A NS1IP
ns2 IN A NS2IP
to the DNS record for advisuals.com in WHM☆☆☆ Cool Domain Names - DomainSale.link☆☆☆

According to a whois search at internic.net/whois.html ns1.advisuals.com has not been registered. The same tool reports ns2.advisuals.com to exist at 173.208.240.204 You need to register ns1.advisuals.com with your domain registrar, wait a few hours and then attempt to repropagate. It's worth noting that dns reules require than your primary and secondary name servers be on entirely different subnets. I see here you are attempting to use the same IP address for both servers. Try using a different IP address and see if that helps. When you think you have everything corrected, then go to intodns.com/advisuals.com. You can check your nameserver status at internic.net/whois.html
