by Imagine opening your laptop to check an important email, join an online meeting, or watch a video. Your Wi-Fi appears connected, but websites refuse to load. Instead, your browser displays an error saying “DNS Server Not Responding.”
It can be frustrating, especially when you need the internet urgently.
Fortunately, the DNS server not responding error in Windows 11 is often caused by temporary network problems, incorrect DNS settings, outdated drivers, or issues with your router.
In this guide, you will learn 9 practical ways to fix DNS server not responding in Windows 11, starting with simple solutions before moving to more advanced troubleshooting.
What Does DNS Server Not Responding Mean?
DNS stands for Domain Name System.
Think of DNS as the internet’s address book. When you type a website name into your browser, a DNS server helps your computer find the IP address associated with that website.
For example, when you enter a website address, your computer asks a DNS server where that website is located.
If the DNS server cannot respond properly, your browser may fail to open the website.
You might see messages such as:
- DNS server not responding
- DNS address could not be found
- DNS_PROBE_FINISHED_BAD_CONFIG
- DNS_PROBE_FINISHED_NXDOMAIN
- No internet access
These errors can have different causes, so the same solution will not work in every situation.
Why Is the DNS Server Not Responding in Windows 11?
Several problems can interfere with DNS resolution.
Common causes include:
- Temporary router or modem problems
- Incorrect DNS server settings
- Corrupted DNS cache
- Internet service provider DNS issues
- Outdated or malfunctioning network drivers
- VPN or proxy configuration problems
- Security software interfering with network requests
- Incorrect Windows network settings
Before changing advanced settings, try the following fixes in order.
1. Restart Your Router and Computer
The simplest solution is often the most effective.
Your router or Windows computer may have a temporary connection problem.
How to restart your network
- Save your work.
- Shut down your Windows 11 computer.
- Turn off your router or modem.
- Wait approximately 30 seconds.
- Turn the router or modem back on.
- Wait until the connection is restored.
- Restart your computer.
Now open your browser and check whether websites load.
Practical tip: If other devices connected to the same Wi-Fi network also cannot access the internet, the problem may be with your router or internet service provider rather than Windows.
2. Run Windows 11 Network Troubleshooting
Windows 11 includes built-in tools that can help identify common network problems.
Steps to troubleshoot the connection
- Open Settings.
- Select System.
- Click Troubleshoot.
- Open Other troubleshooters.
- Find Network and Internet.
- Click Run, or follow the option to open the Get Help troubleshooter.
- Follow the instructions displayed on your screen.
The exact interface may vary depending on your Windows 11 version.
After completing the troubleshooting process, check your internet connection again.
3. Fix DNS Server Not Responding by Flushing DNS Cache
Windows stores DNS information locally to help websites load faster.
However, outdated or incorrect DNS records can sometimes cause connection problems.
Flushing the DNS cache removes these stored records and allows Windows to request fresh information.
How to flush DNS in Windows 11
- Click Start.
- Type Command Prompt.
- Select Run as administrator.
- Enter the following command:
ipconfig /flushdns
- Press Enter.
You should see a message indicating that the DNS Resolver Cache was successfully flushed.
Close Command Prompt and try opening a website.
Important: Flushing DNS does not delete your personal files, browser bookmarks, or saved documents.
4. Change Your DNS Server in Windows 11
Sometimes the DNS server provided by your internet service provider becomes slow or temporarily unavailable.
In that situation, using another trusted DNS provider may help.
How to change DNS settings
- Open Settings.
- Select Network & internet.
- Choose Wi-Fi or Ethernet, depending on your connection.
- Open the properties of your active connection.
- Find DNS server assignment.
- Click Edit.
- Select Manual.
- Enable IPv4.
- Enter your preferred DNS server addresses.
- Save the changes.
For example, Google Public DNS uses:
Preferred DNS: 8.8.8.8
Alternate DNS: 8.8.4.4
You can also use Cloudflare’s public DNS:
Preferred DNS: 1.1.1.1
Alternate DNS: 1.0.0.1
After saving, disconnect and reconnect to your network if necessary.
Note: Changing DNS providers can affect privacy and DNS filtering. If you use a school, office, or managed network, contact your network administrator before changing these settings. Record your previous settings so you can restore them.
5. Restart the DNS Client Service
Windows uses the DNS Client service to manage DNS-related functions.
Checking whether this service is operating normally can help identify a system configuration problem.
How to check DNS Client
- Press Windows + R.
- Type
services.msc. - Press Enter.
- Find DNS Client.
- Check its status.
On many Windows 11 systems, the controls for manually stopping or restarting this service are unavailable. This is normal.
If the service is running, leave it alone and continue to the next solution.
If you suspect the service is not functioning correctly, restart Windows rather than trying to force-stop a protected service.
6. Reset TCP/IP and Winsock Settings
Windows uses TCP/IP and Winsock components to manage network communication.
If these components become misconfigured, resetting them may help restore connectivity.
Reset network components
Open Command Prompt as administrator.
Enter these commands one at a time:
netsh winsock reset
netsh int ip reset
ipconfig /release
ipconfig /renew
ipconfig /flushdns
Press Enter after each command.
Restart your computer when the commands finish.
Important: These commands can temporarily disconnect your network and may reset customized networking settings. If your computer uses a static IP address, VPN, or company-managed network, consult your administrator first.
7. Update Your Network Adapter Driver
An outdated or malfunctioning network driver can cause internet connectivity problems.
Updating the driver may help when DNS errors appear alongside Wi-Fi or Ethernet connection issues.
How to update network drivers
- Right-click the Start button.
- Select Device Manager.
- Expand Network adapters.
- Right-click your active Wi-Fi or Ethernet adapter.
- Select Update driver.
- Choose Search automatically for drivers.
If Windows cannot find a newer driver, check the official support website of your laptop or network adapter manufacturer.
Avoid downloading drivers from unknown websites.
If the issue began immediately after a driver update, you can also check whether the Roll Back Driver option is available in the adapter’s properties.
8. Check VPN, Proxy, and Security Software
VPN applications, proxy settings, and certain security tools can change how DNS requests are handled.
An incorrect configuration may prevent websites from loading.
What to check
VPN connection
If you use a VPN, temporarily disconnect it and test your internet connection.
Proxy settings
- Open Settings.
- Go to Network & internet.
- Select Proxy.
- Review the configured proxy settings.
If you do not intentionally use a manual proxy, check whether an unnecessary manual proxy has been enabled.
Security software
If you suspect security software is blocking DNS traffic, review its network protection settings or contact the software provider.
Do not permanently disable your firewall or antivirus protection simply to solve a DNS error.
Important: If your VPN or proxy is required by your workplace or school, do not change it without permission.
9. Fix DNS Server Not Responding with Network Reset
If none of the previous solutions works, Windows 11 offers a Network Reset feature.
This restores network adapters and related settings to their defaults.
How to reset network settings
- Open Settings.
- Select Network & internet.
- Click Advanced network settings.
- Select Network reset.
- Click Reset now.
- Confirm the action.
- Allow Windows to restart.
After restarting, reconnect to your Wi-Fi network and test your browser.
Warning: Network Reset may remove customized network settings. You may need to reconnect Wi-Fi networks or reconfigure VPN software and virtual network adapters.
For this reason, use Network Reset only after trying the simpler solutions.
How to Check Whether the DNS Problem Is Fixed
After applying a solution, perform these quick checks.
Test 1: Open multiple websites
Try opening two or three familiar websites.
If they load normally, your connection may be working again.
Test 2: Check DNS resolution
Open Command Prompt and enter:
nslookup microsoft.com
If the command returns an IP address, DNS resolution is working for that query.
However, this does not guarantee that every website or network service will work correctly.
Test 3: Compare another device
Connect a smartphone or another computer to the same network.
If all devices experience similar problems, investigate the router or internet service provider.
If only your Windows 11 computer is affected, focus on its network configuration.
