How to Fix DNS Server Not Responding on Windows 11

You open your browser, type a website address, and wait. Instead of the page loading, you see an error such as “DNS server not responding,” “DNS_PROBE_FINISHED_BAD_CONFIG,” or “Server IP address could not be found.”

Your internet connection may appear normal, yet websites refuse to open. Sometimes, one browser stops working while another continues to work. In other cases, every website fails, even though Windows shows that you are connected to Wi-Fi.

These problems can be related to the Domain Name System (DNS), which helps your computer find the servers associated with website names. However, a DNS error does not always mean the DNS server itself is broken. Incorrect network settings, a router problem, a VPN, or a browser’s secure DNS configuration can produce similar symptoms.

This guide explains how to fix the DNS server not responding error on Windows 11, starting with simple checks and moving toward advanced troubleshooting. You will learn how to clear the DNS cache, test your connection, change DNS servers, and identify when the problem requires help from your internet provider.

1. What Does DNS Server Not Responding Mean?

DNS stands for Domain Name System. It translates human-readable website names into IP addresses that computers use to locate online services.

For example, when you enter a website address into your browser, your computer generally needs to resolve that name before it can connect to the destination server.

If DNS resolution fails, the browser may be unable to locate the website even when your Wi-Fi connection is working.

Several things can cause this problem:

• Your internet provider’s DNS server is temporarily unavailable.
• Your router has lost its internet connection.
• Windows has outdated or incorrect DNS information.
• The DNS server configured on your computer is unreachable.
• A VPN or proxy is interfering with network requests.
• Your browser has a separate Secure DNS configuration.
• A firewall or security application is blocking DNS traffic.
• Your network adapter or Windows network configuration has a problem.

The error message alone does not identify which cause applies to your computer. That is why testing the connection before changing settings is important.

2. Check Whether the Problem Affects Every Device

Before modifying DNS settings, determine whether the problem is limited to your Windows computer.

Take your phone or another laptop and connect it to the same Wi-Fi network. If possible, temporarily turn off mobile data on your phone so the test uses Wi-Fi only.

Try opening several websites.

If every device has the same problem: The issue may be related to your router, internet service, or the DNS servers supplied by your provider.

If other devices work normally: The problem may be limited to your Windows computer, browser, VPN, or network configuration.

You can also test a different browser on the affected computer. For example, if a website fails in Chrome but opens in Edge, investigate the browser’s settings before changing the entire Windows network configuration.

This quick comparison helps you choose the right troubleshooting path and avoids unnecessary changes.

3. Restart Your Router and Computer

A router can occasionally experience temporary connectivity or DNS-forwarding problems. Restarting it may restore normal communication.

Follow these steps:

1. Save your work and close applications that require a stable internet connection.
2. Turn off your router using its power switch or unplug its power cable.
3. If you have a separate modem or optical network terminal, follow your provider’s instructions for restarting it.
4. Wait approximately 30 seconds before reconnecting the equipment.
5. If the modem and router are separate, allow the modem or ONT to reconnect before powering on the router.
6. Wait until the connection indicators stabilize.
7. Restart your Windows computer.
8. Open your browser and test the website again.

If you use a combined modem-router device, a normal power restart is generally sufficient.

Do not press and hold the router’s factory reset button. A factory reset can erase saved network names, passwords, and provider-specific settings.

If DNS starts working again but the error returns frequently, investigate the router, its firmware, and the DNS settings provided by your internet service.

4. Run the Windows Network Troubleshooter

Windows 11 includes automated diagnostics that can identify certain internet and network configuration problems.

Microsoft recommends using the Get Help app to run its network troubleshooting flow.

To try it:

1. Open the Start menu.
2. Search for Get Help.
3. Open the application.
4. Search for internet connection or network troubleshooting.
5. Follow the instructions provided by the diagnostic tool.

The available troubleshooting options may differ between Windows versions.

If the tool identifies a problem, follow its recommended repair and test your connection again.

Keep in mind that the troubleshooter may not identify every DNS issue. If it reports that no problem was found, continue with the following methods.

5. Flush the DNS Cache

Windows keeps a local DNS resolver cache to avoid repeatedly looking up domain names that it has already resolved.

Occasionally, cached information can contribute to a website access problem. Clearing the cache forces Windows to request DNS information again when needed.

This is one of the easiest ways to troubleshoot a potential DNS cache issue.

Step 1: Open Command Prompt

1. Open the Start menu.
2. Search for Command Prompt.
3. Select Run as administrator.
4. Approve the permission prompt.

Step 2: Flush the DNS cache

Enter the following command:

ipconfig /flushdns

Press Enter.

Windows should display a message confirming that the DNS resolver cache was successfully flushed.

Step 3: Test the website again

Close Command Prompt and open your browser. Try visiting the affected website.

If the page loads, the cached information may have contributed to the problem.

If the error remains, do not repeatedly flush the cache expecting a different result. Move to the next step.

Important: Flushing the DNS cache does not change your configured DNS server, repair a disconnected router, or restore a DNS server that is offline. It only clears the local resolver cache maintained by Windows.

6. Renew Your IP Address and Reset Network Components

If flushing the DNS cache does not help, your computer may have an incorrect IP configuration or another network-related problem.

Windows provides commands that can renew the IP address and reset certain networking components.

Open Command Prompt as administrator and run these commands one at a time.

Release the current IP address

ipconfig /release

Press Enter.

This releases the current IPv4 address for the relevant adapters. Your computer may temporarily lose network connectivity.

Request a new IP address

ipconfig /renew

Press Enter.

Windows attempts to obtain a fresh IP configuration from the network’s DHCP server, usually your router.

If the command fails, note the error message. The issue may involve DHCP, the router, or the network adapter rather than DNS alone.

Reset Winsock

netsh winsock reset

This resets the Windows Winsock catalog, which supports network communication for applications.

Reset the TCP/IP stack

netsh int ip reset

This resets important TCP/IP configuration components.

After running these commands, restart your computer and test your connection.

These commands can affect custom networking configurations. If you use a work VPN, a managed network, or manually configured IP settings, consult your administrator before resetting them.

7. Change Your DNS Server on Windows 11

If your configured DNS server is unavailable or not resolving domain names correctly, switching to another reputable DNS resolver may help.

Windows normally receives DNS settings automatically from your router or network. A manual DNS configuration lets you use another resolver instead.

Two widely used public DNS services are Google Public DNS and Cloudflare’s public resolver.

These are alternative DNS resolvers, not guaranteed fixes. If the underlying internet connection is down, changing DNS will not restore it.

How to change DNS settings

1. Open Settings.
2. Select Network & internet.
3. Choose your active Wi-Fi or Ethernet connection.
4. Find DNS server assignment.
5. Select Edit.
6. Change the setting from Automatic (DHCP) to Manual.
7. Enable IPv4.
8. Enter the preferred and alternate DNS addresses for your chosen provider.
9. Save the changes.

The exact interface may vary slightly between Windows 11 builds.

For example, if you choose Cloudflare, enter 1.1.1.1 as the preferred address and 1.0.0.1 as the alternate address.

After saving, open Command Prompt and run:

ipconfig /flushdns

Then try opening several websites.

What if changing DNS does not help?

If the error remains, the problem may not be the DNS resolver you originally used.

Check whether your computer has internet connectivity, whether the DNS server is reachable, and whether a VPN or browser-specific setting is overriding your configuration.

If your network requires a specific DNS server, such as a workplace or university network, restore the original settings or contact the network administrator.

Also remember to record your previous DNS settings before changing them so you can restore them if necessary.

8. Disable VPN and Check Proxy Settings

VPN applications and proxy servers can change how your computer routes internet traffic and resolves domain names.

If the DNS error appeared after installing a VPN or changing proxy settings, temporarily disconnect the VPN and investigate the proxy configuration.

Disconnect the VPN temporarily

Open your VPN application and disconnect from the current server.

Try opening the website again.

If the website works after disconnecting, investigate the VPN server, application settings, and DNS configuration. Do not assume that the VPN must be removed; the issue may be limited to a particular server or setting.

If the computer belongs to your employer, follow the organization’s instructions before changing VPN settings.

Review Windows proxy settings

1. Open Settings.
2. Select Network & internet.
3. Choose Proxy.
4. Review the available configuration options.
5. If a manual proxy is enabled unexpectedly, investigate its purpose before disabling it.

Some organizations intentionally use proxies. Disabling a required proxy can stop legitimate network access, so do not change managed settings without permission.

After reviewing these settings, test the affected website again.

9. Check Secure DNS in Your Browser

One detail that is easy to miss is that your browser may use a different DNS configuration from the one configured in Windows.

Modern browsers can support DNS over HTTPS (DoH), commonly called Secure DNS. This sends DNS queries through an encrypted HTTPS connection to a compatible resolver.

Secure DNS can improve privacy, but a browser-specific configuration may also create connectivity issues if its chosen resolver is unavailable or blocked by the network.

If Windows applications work but one browser cannot open websites, check this setting.

In Google Chrome

1. Open Chrome.
2. Select the three-dot menu.
3. Open Settings.
4. Select Privacy and security.
5. Open Security.
6. Find Use secure DNS.
7. Review the selected provider.

In Microsoft Edge

1. Open Edge.
2. Select the three-dot menu.
3. Open Settings.
4. Select Privacy, search, and services.
5. Find the Security section.
6. Review the Use secure DNS setting and selected provider.

The available options depend on the browser version.

If you suspect the selected provider is causing the issue, try the browser’s default or another supported resolver, or temporarily disable Secure DNS for testing if the browser allows it.

Avoid turning off privacy protections permanently without a reason. If you change the setting, test the connection and restore your preferred configuration if it makes no difference.

10. Restart the DNS Client Service

Windows includes a service called DNS Client that supports DNS-related functionality, including caching and name resolution.

In some troubleshooting situations, checking the service can help identify a Windows configuration issue. However, the service may be managed by Windows, and its controls can be restricted depending on the system.

To inspect it:

1. Press Windows + R.
2. Type services.msc.
3. Press Enter.
4. Find DNS Client in the service list.
5. Open its properties if available.
6. Review its status and startup configuration.

Do not change the startup type or attempt to force-stop a protected system service just because a website is failing. Windows manages some services automatically, and their behavior can vary by configuration.

If the service is running normally, continue with the network driver and security checks instead of repeatedly trying to restart it.

11. Update Your Network Adapter Driver

An outdated or incompatible network driver can cause connectivity issues that appear to be DNS problems.

This is especially worth checking if the error began after a Windows update or if your internet connection drops frequently.

Follow these steps:

1. Right-click Start.
2. Open Device Manager.
3. Expand Network adapters.
4. Identify your Wi-Fi or Ethernet adapter.
5. Right-click the adapter.
6. Select Update driver.
7. Choose Search automatically for drivers.

If Windows cannot find an appropriate update, visit your laptop or network adapter manufacturer’s official support website.

Search for your exact computer model and download the compatible network driver for your Windows version.

If your computer cannot access the internet, use another device to download the driver and transfer it with a USB drive.

Before uninstalling an existing driver, make sure you have a suitable replacement available. After installing the driver, restart the computer if required and test the connection.

12. Check Firewall and Security Software

Security software can sometimes block network requests or interfere with particular applications.

If the DNS error occurs only in one application, investigate that application’s network settings and any firewall rules associated with it.

If you recently installed a third-party firewall, antivirus product, parental-control application, or DNS-filtering utility, check whether it has a network protection feature that may be affecting DNS resolution.

Do not disable Windows Firewall permanently or turn off antivirus protection without a clear reason.

Instead:

• Review recent security software changes.
• Check whether the affected application is being blocked.
• Inspect any custom DNS filtering or parental-control settings.
• Follow the security product’s official troubleshooting instructions.

If you suspect a security product is responsible, use its supported diagnostic process and restore normal protection after testing.

13. When to Contact Your Internet Provider

If none of the previous methods works, the DNS problem may originate outside your computer.

Your internet provider may operate the DNS resolver assigned to your connection. If that resolver is unavailable, affected websites may fail to open even when your local Wi-Fi is functioning.

Contact your provider if:

• Multiple devices experience the same DNS error.
• Restarting the router does not help.
• The provider’s DNS servers are consistently unreachable.
• The connection fails across different devices and applications.
• The problem returns frequently after temporary fixes.

Before contacting support, note the exact error message, when the problem started, and whether switching DNS servers changed anything.

This information helps the provider distinguish a DNS issue from a broader internet connection problem.

Frequently Asked Questions

What causes the DNS server not responding error?

Common causes include an unavailable DNS resolver, incorrect DNS settings, a router issue, a VPN or proxy conflict, browser Secure DNS configuration, and network adapter problems. The error itself does not identify a single cause.

How do I fix DNS server not responding on Windows 11 quickly?

First, check whether other devices can open websites through the same network. Restart your router if several devices are affected. If the problem is limited to Windows, try ipconfig /flushdns, check your VPN and proxy settings, and consider changing to a reputable DNS resolver.

Is it safe to change my DNS server?

Using a reputable public DNS resolver is generally a normal troubleshooting option. However, DNS providers can differ in privacy practices, filtering, and compatibility. Use a provider you trust and preserve your original settings so you can restore them if necessary.

Will flushing DNS delete my browsing history?

No. The ipconfig /flushdns command clears the Windows DNS resolver cache. It does not delete your browser history, bookmarks, saved passwords, or personal files.

Why does DNS work in one browser but not another?

Browsers may use different Secure DNS providers, extensions, proxy settings, or cached information. Compare the browsers’ DNS settings and test whether the issue occurs in other applications before changing Windows-wide settings.

Should I disable IPv6 to fix DNS errors?

Not as a routine first step. IPv6 is a standard networking protocol, and disabling it can create other connectivity problems. Investigate the DNS configuration and connection first. Change IPv6 settings only when you have evidence that they are involved and understand how to restore them.

Does changing DNS make my internet faster?

It can improve the time required to resolve domain names in some circumstances, but it does not increase the underlying bandwidth supplied by your internet provider. Performance depends on several factors, including the resolver, network route, and connection quality.

Can a DNS error be caused by my router?

Yes. A router may have lost its internet connection, may be forwarding DNS requests incorrectly, or may be using an unavailable DNS resolver. Testing another device and restarting the router can help identify whether the problem is local to your computer.

Conclusion

The DNS server not responding error on Windows 11 can result from several different problems, so the best fix depends on where the connection is failing.

Start by testing other devices, restarting your router, and running the Windows network troubleshooter. If the problem affects only your computer, flush the DNS cache, renew the IP address, review VPN and proxy settings, and check your browser’s Secure DNS configuration.

Changing to a reputable public DNS resolver may help when the original resolver is unavailable. If the issue continues, inspect the network adapter driver and contact your internet provider when multiple devices are affected.

Avoid making several changes at once. Test your connection after each step so you can identify which action actually helped. This approach is safer, easier to troubleshoot, and more likely to reveal the underlying cause.
