>1) check your laptop is configured to work with this DNS server (cat /etc/resolv.conf on laptop or "ipconfig /all | findstr DNS" in case of windows )

My laptop and the server are in two different countries. Btw, laptop also run FreeBSD.



>2) check server is accessible (ping <YOUR_SERVER_IP> from laptop)

Yes, the server is accessible (ping <YOUR_SERVER_IP> from the laptop.


>3) check server is accessible via TCP/53 ("telnet <YOUR_SERVER_IP> 53" from your laptop) 

No, there was a reverse DNS error here. It was pointing to the Reverse DNS server of the data centre.

Now its been corrected:

telnet <YOUR_SERVER_IP> 53
Trying <YOUR_SERVER_IP>...
Connected to ns1.mydomain.com.
Escape character is '^]'.

>4) check firewall on server and/or devices between server and laptop, it may block requests

No firewall on the server yet. 


>5) check your server is configured to use the same DNS: cat /etc/resolv.conf 
>
nameserver 127.0.0.1
nameserver other_ip1
nameserver other_ip2


Although the Reverse DNS is now been corrected, still cannot ping as from the laptop:
ping www.mydomain.com
ping: cannot resolve www.mydomain.com: Host name lookup failure

Any ideas?
