When you try to connect to the Internet – but cannot then you may run the Network Diagnostic Troubleshooter to troubleshoot the issue. But at the time, the Troubleshooter itself may throw up the following error message:
Your computer appears to be correctly configured, but the device or resource (DNS server) is not responding.
DNS Server is not responding
If you face DNS issues or problems on your Windows 10/8/7 computer, here are few things you could try to resolve the Your computer appears to be correctly configured, but the device or resource (DNS server) is not responding error:
- Change the DNS server address manually
- Use alternative DNS
- Enter Physical address in the Network adapter setting
- Disable your Firewall.
Fix DNS issues & problems
Before you begin, backup your Router settings and update the firmware of your Router. Check the Router manual for more information on this subject.
1] Change the DNS server address manually
The first thing to try is to change the DNS server address manually. Follow these instructions-
Go to Start and Click on Control Panel
Open up Network and Internet and go to the Network and Sharing Center.
Click on Change adapter settings.
Now you’ll see the list of Network adapters. Select the Network adapter that you are using and right-click on it and open Properties.
Click on “Internet Protocol Version 4 (TCP/IPv4)”
You’ll see the Internet Protocol Properties.
Select “Use the Following DNS server address:”
Enter the Preferred DNS address: 184.108.40.206
Enter the Alternative DNS address: 220.127.116.11
Also, select Validate settings upon exit check-box.
Click OK, and exit.
Now you have to enter the same DNS address in the Router configuration as well. You may refer the Router manual for more information on this.
2] Use alternative DNS
If this does not help, you may try to install and configure OpenDNS and see if that helps.
3] Enter Physical address in the Network adapter setting
The next suggestion I have to make is entering the Physical address in the Network adapter setting and seeing if that works for you.
To do this-
- Go to Start and type in CMD and Hit Enter
- In command prompt type in IPCONFIG /ALL
- Look for your network adapter
- Write down the Physical Address. According to this screenshot, it’s 78-DD-08-F1-DF-B0 in my case.
Now go to Start and type in NCPA.CPL. Right Click on your Network adapter and go to Properties.
Then follow these steps-
- Click on Advanced Tab and select Network address
- Select the radial button Value
- Type in the physical address you wrote down before, (In my case it was 78-DD-08-F1-DF-B0) Remove the dashes when you type in, i.e., 78DD08F1DFB.
- Click OK
- Reboot the System.
Now look up your Network adapter model and go to the manufactures website and find the appropriate drivers and update the Drivers and see if that resolves your issue.
4] Disable your Firewall
The last suggestion I have to make is to disable your Firewall completely and see if that helps your connection.
Hope something helps.
