stephdl has advised you that you cannot ping your DNS server, you should use the dig command in the correct format advised (actual example as shown at start of my previous my post).
Please show the output of the same command I used, my response from my location appears OK, but that may not be the same response you receive.

As you do not say what your problem is then no one can help you.

Try using the command you were advised

dig any altawi.com.sa @212.93.192.5

; <<>> DiG 9.3.6-P1-RedHat-9.3.6-25.P1.el5_11.3 <<>> any altawi.com.sa @212.93.192.5

dns are complex and I know/understand just a little part. Above is what your external domain name server is responding to your request. The fact that you have an answer is a good thing but you have to analyse and compare from another dns provider what is present here.

If I'm wrong, please correct me


--- Quote ---dig any altawi.com.sa @212.93.192.5 -> you are asking to the external dns server 212.93.192.5 (remove @212.93.192.5 and you will use the default dns server of your computer)

When you have an issue with your dns, you have to compare with another dns provider like google (8.8.4.4) or the dns server of your internet provider.


--- Quote ---altawi.com.sa.          14400   IN      MX      1 altawi.com.sa. -> MX = mail exchanger which is managed by altawi.com.sa
altawi.com.sa.          86400   IN      NS      ns2.awalnet.net.sa. -> NS = name server which is managed by ns2.awalnet.net.sa and webx1.awalnet.com
altawi.com.sa.          14400   IN      A       212.93.222.10 -> the record A is the IP address of your server which handle the domain  altawi.com.sa
altawi.com.sa.          86400   IN      SOA     webx1.awalnet.com. aoulah.stcas.com.sa. 2015073002 86400 7200 3600000 86400 -> SOA = Start of authority
;; SERVER: 212.93.192.5#53(212.93.192.5) -> the dns server which had answered => @212.93.192.5
