If you are browsing the internet and suddenly see the message DNS Server Not Responding, it can be confusing because your WiFi may still show as connected. I have faced this type of problem several times, and in many cases, the internet connection itself is not completely broken. The issue is often related to DNS settings, the router, network configuration, or the DNS service being used by your device.
DNS plays an important role in connecting you to websites. When it stops working properly, your browser may fail to open websites even though your computer appears to have an active internet connection.
In this guide, I will explain what the DNS Server Not Responding error means and share practical step by step solutions that you can try on Windows and other devices.
What Does DNS Server Not Responding Mean?
DNS stands for Domain Name System. Its main job is to translate website names into IP addresses that computers can understand.
For example, when you type a website address into your browser, your device needs to find the IP address associated with that website. Your DNS server handles this request.
If the DNS server does not respond, your computer may not be able to find the website. As a result, Chrome, Edge, Firefox, or another browser can show an error such as DNS Server Not Responding.
The good thing is that this problem is usually fixable without complicated technical knowledge.
Common Causes of DNS Server Not Responding
There can be several reasons behind this error. From my experience, the most common causes include an unstable internet connection, a temporary router problem, incorrect DNS settings, outdated network drivers, corrupted DNS cache, VPN interference, or problems with the DNS server provided by your internet service provider.
Sometimes the problem is temporary and disappears after restarting the router. In other situations, changing the DNS server can solve the issue immediately.
Before making complicated changes, I recommend starting with the simple solutions first.
1. Check Your Internet Connection
The first thing I normally check when websites stop loading is the internet connection itself.
Look at the WiFi or Ethernet icon on your computer. If the connection appears disconnected, reconnect to your network.
You can also try opening a different website. If none of the websites open, the problem may not be limited to DNS.
Another useful test is to connect your computer to a mobile hotspot. If websites work normally through the hotspot, your computer is probably fine and the issue may be related to your router or internet service.
2. Restart Your Router
Restarting the router is one of the easiest solutions for DNS problems.
Turn off your router and unplug its power cable. Wait around 30 seconds before plugging it back in. Give the router a few minutes to reconnect to the internet.
After that, connect your computer again and try opening a website.
Routers can sometimes experience temporary network or DNS related problems. A restart gives the device a fresh connection and can resolve these temporary issues.
3. Restart Your Computer
A simple computer restart can also solve DNS Server Not Responding problems.
Windows network services can occasionally become stuck or behave unexpectedly. Restarting the computer reloads these services and creates a fresh network connection.
Before changing advanced settings, I recommend restarting your PC because it takes only a minute and can save you unnecessary troubleshooting.
4. Flush the DNS Cache
Windows stores DNS information in a local cache. This helps websites load faster, but sometimes the cached information becomes outdated or corrupted.
You can clear this cache using Command Prompt.
Open the Start menu and search for Command Prompt. Right click it and select Run as administrator.
Then enter:
ipconfig /flushdns
Press Enter.
You should see a message confirming that the DNS Resolver Cache was successfully flushed.
Now close Command Prompt and try opening the website again.
This is one of the first DNS fixes I recommend because it is quick and does not change your permanent network settings.
5. Renew Your IP Address
If flushing the DNS cache does not help, you can renew your IP address.
Open Command Prompt as administrator and run:
ipconfig /release
Press Enter and wait for the command to complete.
Then enter:
ipconfig /renew
Press Enter again.
Windows will request a new IP address from your router. Once the process finishes, try browsing again.
This can help when the computer has an IP configuration problem.
6. Change Your DNS Server
Sometimes the DNS server provided automatically by your internet service provider is slow or temporarily unavailable.
In that situation, switching to another reliable DNS service can help.
Popular public DNS options include Google DNS and Cloudflare DNS.
Google DNS uses:
8.8.8.8
8.8.4.4
Cloudflare DNS uses:
1.1.1.1
1.0.0.1
On Windows, open Settings, go to Network & Internet, select your connected network, and open the DNS settings.
Depending on your version of Windows, the exact menu names may be slightly different.
Choose the option to edit DNS settings and manually enter the preferred and alternate DNS addresses.
Save the changes and restart your browser.
If the DNS Server Not Responding error was caused by an unreliable DNS server from your ISP, this solution can make a noticeable difference.
7. Disable VPN Temporarily
If you use a VPN, try disconnecting it temporarily.
Some VPN applications route DNS requests through their own servers. If the VPN connection or DNS configuration has a problem, websites may stop loading.
Disconnect the VPN and test your internet connection again.
If the internet starts working after disconnecting the VPN, check the VPN application’s DNS or network settings. You can also update the VPN application to its latest version.
I recommend testing this before making major Windows network changes.
8. Disable Antivirus Web Protection Temporarily
Security software can sometimes interfere with network traffic.
Some antivirus programs include web protection, DNS filtering, or secure browsing features. If one of these components is malfunctioning, it may prevent websites from loading correctly.
If you suspect your security software, temporarily disable its web protection feature and test a website.
Do not leave your antivirus protection disabled permanently. The purpose of this step is only to identify whether the security software is causing the problem.
If disabling a particular feature fixes the problem, check for an update or review the software’s network protection settings.
9. Use Windows Network Troubleshooter
Windows includes built in troubleshooting tools that can automatically detect some network problems.
Open Settings and go to System, then Troubleshoot, followed by Other troubleshooters.
Look for the network or internet connection troubleshooter and run it.
Windows may identify problems with your network adapter, IP configuration, or connection.
This method does not fix every DNS problem, but it is worth trying because it requires very little technical knowledge.
10. Reset Network Settings
If none of the previous solutions work, resetting the network settings can be useful.
Windows provides a network reset option that reinstalls network adapters and returns important network settings to their default state.
Before using this option, remember that you may need to reconnect to WiFi networks afterward.
Go to Settings, select Network & Internet, and look for Advanced network settings. From there, find the network reset option.
After the reset, Windows will restart your computer.
Once Windows starts again, connect to your WiFi network and test your internet connection.
I recommend using network reset as one of the final Windows troubleshooting steps because it affects your existing network configuration.
11. Update Your Network Driver
An outdated or corrupted network adapter driver can also cause connection problems.
Open Device Manager and expand Network adapters.
Find your WiFi or Ethernet adapter, right click it, and select the option to update the driver.
If Windows cannot find a newer driver, you can visit your computer or motherboard manufacturer’s official website and download the appropriate network driver.
Be careful when downloading drivers. I recommend using the manufacturer’s website rather than random driver download websites.
12. Check Whether the Problem Happens on Other Devices
One of the easiest ways to identify where the problem is located is to test another device.
Connect your phone or another computer to the same WiFi network and try opening a website.
If websites work normally on other devices but not on your computer, the issue is probably related to your computer.
If every device connected to the same router has the DNS Server Not Responding error, the router or internet service may be responsible.
This simple test can save a lot of time because it helps you determine whether you should troubleshoot the PC or the network.
13. Restart Your Network Adapter
Windows allows you to disable and enable a network adapter.
Open Settings and go to your network settings. You can also use Device Manager to locate your network adapter.
Disable the adapter, wait a few seconds, and then enable it again.
This forces Windows to reinitialize the network hardware and can sometimes fix temporary connection problems.
What If DNS Server Not Responding Keeps Coming Back?
If the problem keeps returning, I would look for the underlying cause instead of repeatedly flushing the DNS cache.
Check whether your router firmware is up to date. Also check whether your internet service provider is experiencing DNS or connectivity problems.
If the problem happens only at certain times of the day, your ISP connection may be unstable.
If it happens only when a VPN is connected, investigate the VPN settings.
If it occurs only on one computer, focus on the Windows network configuration, drivers, security software, and DNS settings.
Finding the pattern usually makes troubleshooting much easier.
Final Thoughts
The DNS Server Not Responding error can look serious, but in many cases it is caused by a simple network configuration or temporary DNS problem.
I recommend starting with the basic solutions. Check the internet connection, restart the router and computer, flush the DNS cache, and renew the IP address. If the problem continues, changing the DNS server to a reliable public DNS service can be a useful next step.
For more difficult cases, check your VPN, antivirus software, network adapter, and Windows network settings. If every device on your network has the same problem, contact your internet service provider because the issue may be outside your computer.
The most important thing is not to change everything at once. Try one solution at a time and test your connection after each change. This makes it much easier to understand what actually fixed the DNS problem.
With these step by step solutions, you should be able to troubleshoot most common DNS Server Not Responding errors and get your internet connection working again.
