DNS server not responding

Hi Jubair,

Based on the information that you've provided, there's a possibility that your TCP/IP is broken or corrupted. Transmission Control Protocol/Internet Protocol (TCP/IP) is the language that a computer uses to access the Internet.

To help you with this concern, we suggest resetting of your TCP/IP by using the NetShell utility. You may reset TCP/IP automatically or manually. Please follow the methods below:

Method 1: Reset TCP/IP automatically

To reset TCP/IP automatically, download this **file**. In the File Download dialog box, click Run or Open, and then follow the steps in the easy fix wizard.

Method 2: Manually reset TCP/IP including winsock

1. On the Start screen, type CMD. In the search results, right-click Command Prompt, and then select Run as administrator. At the command prompt, enter the following command, and then press Enter:

netsh int ip reset c:\resetlog.txt

netsh winsock resetNote: If you don't want to specify a directory path for the log file, run the following command instead (please includenetsh winsock reset if you plan to use this method instead) : netsh int ip reset 2. Restart the computer, then check if the issue was sorted out.

If the issue still persists after performing the suggested steps above, you may need to seek further assistance from your ISP. As you've mentioned in your post, the issue usually gets fixed when you turn your router off and turn it on. There's a chance that there are components of the router that triggers the issue, you may check with your ISP if a replacement of your router is applicable.

For any results, just send us a reply.

Hey Elieen Gal, thanks for answering to this issue. I tried to use method 1, it found that problem then followed the instructions (like ok/restart)

But the problem occured again just the way it did before. But i will go with your second option later after in a moments.

If you don't mind me asking i just want to know what could be the possible reason behind this? I'm not a hardware person nor a tech guy so i don't know whom to ask and get the answer, as you seems to know stuffs like this so i thought i should try to ask again :)) 

**The problem happens through lan port(not wifi) router which forces me to turn the power off and then again turning on to use internet through lan.

I haven't got the solutions yet!

Sounds like the problem is in the router.  You can override the router's DNS relay.  One way is to use  netsh.

First use netsh to see what you have for  DNS  

netsh  in  ip  sh  dn

Then there is a corresponding  set  command to do the override.   Here's how to get the syntax

netsh in ip se dn ?

Otherwise, please use the above show command as a diagnostic to elaborate on what you mean by

4. Tried changing dns server from both router and from pc(network and settings- manually) but not worked

FWIW I ran into this problem symptom yesterday when I found that somehow my Ethernet DNS had picked up an invalid address.  (I had been off site earlier so that may have had something to do with it.)  I am currently switched to Wi-Fi which has had the same effect of avoiding the Ethernet.  It remains to be seen what will happen when I reboot and get the Ethernet by default again.  Maybe by then the lease will have expired or something.
