DNS Server Not Responding
Windows 11 — 10 Fixes That Work

Internet connected but websites won't load? This one error is the most misunderstood Windows 11 problem — and the easiest to fix permanently.

📅 March 7, 2026 ⏱ 8 min read 💻 All Windows 11 Versions ✅ Tested on Real Devices
💬 True story: Last week a reader messaged me — “My internet works on my phone but not my PC. I’ve tried everything.” I asked one question: “Did you try changing your DNS server?” She hadn’t. Two minutes later — fixed. That’s how simple this usually is. Here’s everything that works, from easiest to most advanced. — Bharat Choudhary, FixTechUSA  ·  Windows Networking Specialist
You run the Windows Network Diagnostics and it says “DNS Server Not Responding” — but your WiFi is connected, the router lights are green, and your phone works fine. Frustrating, right? Here’s the truth: in 90% of cases, this is fixed by either changing your DNS server or flushing the DNS cache — both take under 2 minutes. Work through these 10 fixes in order and you’ll be back online fast.
🔎 Quick Test First — Is It Your PC or Your Router?

Before fixing anything, figure out where the problem is. This saves you 10 minutes.

✅ Phone/Tablet works on same WiFi?
Problem is on your Windows 11 PC only. Follow all fixes below.
❌ ALL devices fail on this WiFi?
Problem is your router or ISP. Restart router first — then Fix 1.

🔍 What Causes DNS Server Not Responding in Windows 11?

DNS translates website names (like google.com) into IP addresses. When this translation fails, you get this error — even though your internet connection itself is working perfectly.

🌐
ISP DNS down — Your ISP’s DNS server is overloaded or unavailable
💾
Corrupted DNS cache — Old incorrect records stuck in Windows cache
🛡
Antivirus blocking — Security software intercepting DNS requests
🔧
TCP/IP corruption — Windows update broke the network stack
🌎
Wrong DNS settings — Manual DNS set to non-working server
🖥
Driver conflict — Network adapter driver outdated or corrupted
🔧 10 Fixes — Start From #1
1

Restart Router and Modem

⏱ 2 min  |  🟢 Easy  |  Always do this first

Before anything else — restart your router. Most DNS errors are actually caused by the router’s DNS cache getting stuck, not Windows itself. A router restart clears it instantly.

  1. Unplug your router from power → wait 30 seconds (not 5 seconds — 30 seconds)
  2. Plug router back in → wait for all lights to stabilize (1-2 minutes)
  3. Also restart your Windows 11 PC
  4. Try opening a website
✅This alone fixes the DNS error for 30-40% of users. If it doesn’t work — the problem is on your PC, not the router. Continue to Fix 2.

Change DNS to Google or Cloudflare — Best Permanent Fix

⏱ 2 min  |  🟢 Easy  |  Permanent fix for most users

Your ISP’s DNS server is slow, unreliable, or temporarily down. Switching to Google DNS (8.8.8.8) or Cloudflare DNS (1.1.1.1) bypasses your ISP completely — this is the most effective permanent fix for DNS errors.

  1. Press Win + R → type ncpa.cpl → press Enter
  2. Right-click your active network adapter (WiFi or Ethernet) → Properties
  3. Double-click Internet Protocol Version 4 (TCP/IPv4)
  4. Select “Use the following DNS server addresses”
  5. Enter one of these options:
🔌 Best DNS Servers for Windows 11 (2026)
ProviderPreferred DNSAlternate DNSSpeed
🟢 Google 8.8.8.8 8.8.4.4
🔵 Cloudflare 1.1.1.1 1.0.0.1
🟠 OpenDNS 208.67.222.222 208.67.220.220
  1. Click OK → OK → close window
  2. Open browser → test any website
✅My recommendation: Use Cloudflare (1.1.1.1) — it’s the fastest DNS on the planet and 100% private. Google (8.8.8.8) is equally reliable and the safest choice for beginners.
📌Also do this for IPv6 — double-click IPv6 → set Preferred to 2001:4860:4860::8888 (Google IPv6 DNS).

Flush DNS Cache

⏱ 1 min  |  🟢 Easy  |  Clears corrupted DNS records

Windows stores DNS records locally to speed up browsing. When these records get corrupted or outdated, DNS resolution fails entirely. Flushing removes all old records and forces fresh lookups.

  1. Search cmd in Start → right-click → Run as administrator
  2. Run these commands:
// Flush DNS cache — run all three ipconfig /flushdns
ipconfig /registerdns
ipconfig /release
ipconfig /renew
  1. You should see: Successfully flushed the DNS Resolver Cache
  2. Restart browser → test connection
✅Flushing DNS often fixes errors like ERR_NAME_NOT_RESOLVED and DNS_PROBE_FINISHED_NXDOMAIN in Chrome and Edge too.
4

Reset TCP/IP Stack & Winsock

⏱ 3 min  |  🟡 Medium  |  Best fix after Windows updates

Windows updates frequently corrupt the core networking stack. This complete reset restores TCP/IP and Winsock to factory defaults — fixing DNS errors that nothing else can solve.

  1. Open Command Prompt as administrator
  2. Run each command, pressing Enter after each:
// Complete network reset — run all commands netsh int ip reset
netsh int ipv6 reset
netsh winsock reset
ipconfig /flushdns
ipconfig /release
ipconfig /renew
  1. Restart your PC — mandatory for changes to apply fully
✅This is the single best fix for DNS errors that started immediately after a Windows 11 update.

5

Disable Antivirus & Firewall Temporarily

⏱ 2 min  |  🟢 Easy  |  Fixes security software conflicts

Third-party antivirus programs like Avast, AVG, McAfee, Kaspersky often intercept DNS requests and block them if they consider a domain suspicious. This can cause the DNS Server Not Responding error for every website.

  1. Temporarily disable your antivirus (right-click system tray icon → Disable / Pause protection)
  2. Also disable Windows Firewall: Win + I → Privacy & Security → Windows Security → Firewall
  3. Test your internet connection
  4. If it works — your antivirus is the problem
  5. Re-enable everything after testing
⚠️Only disable antivirus for testing — maximum 5 minutes. If antivirus is the cause, add your browser to its whitelist rather than disabling it permanently.
📌VPN users: If you have a VPN active — disconnect it. VPNs use their own DNS servers which can fail and cause this exact error.
6

Disable IPv6 on Network Adapter

⏱ 2 min  |  🟢 Easy

IPv6 and IPv4 DNS queries sometimes conflict on Windows 11, causing DNS to fail silently. Disabling IPv6 forces all DNS traffic through IPv4 — which is fully supported by all public DNS servers.

  1. Press Win + R → type ncpa.cpl → Enter
  2. Right-click your WiFi or Ethernet adapter → Properties
  3. Find Internet Protocol Version 6 (TCP/IPv6)
  4. Uncheck the checkbox → click OK
  5. Restart PC → test connection
📌Safe for all home networks. You can re-enable IPv6 anytime from the same location if needed.
7

Clear Browser DNS Cache (Chrome / Edge)

⏱ 1 min  |  🟢 Easy  |  For browser-specific DNS errors

Browsers maintain their own separate DNS cache apart from Windows. If a website fails only in Chrome or Edge but works in another browser, the browser DNS cache is corrupted.

Google Chrome:

  1. Type in address bar: chrome://net-internals/#dns
  2. Click Clear host cache
  3. Also go to: chrome://net-internals/#sockets → click Flush socket pools

Microsoft Edge:

  1. Type: edge://net-internals/#dns
  2. Click Clear host cache
✅This instantly fixes ERR_NAME_NOT_RESOLVED errors in Chrome and Edge that happen only on specific websites.

Update or Reinstall Network Adapter Driver

⏱ 5 min  |  🟡 Medium

An outdated or corrupted network driver can cause DNS queries to fail silently. Reinstalling gives Windows a fresh driver that handles DNS correctly.

  1. Press Win + X → Device Manager
  2. Expand Network Adapters
  3. Right-click your WiFi or Ethernet adapter → Update driver
  4. If no update found → right-click → Uninstall device
  5. Check “Delete the driver software” → Uninstall
  6. Restart PC — Windows reinstalls driver automatically
✅For laptops: download the exact driver from Dell, HP, Lenovo, or ASUS support page and install manually — much more stable than Windows auto-install.
9

Disable Proxy Settings

⏱ 1 min  |  🟢 Easy  |  Fixes proxy-caused DNS failures

If a proxy server is configured in Windows — all DNS traffic is routed through it. If the proxy is down or misconfigured, every DNS request fails with this error.

  1. Press Win + I → Network & Internet → Proxy
  2. Under Manual proxy setup — turn OFF Use a proxy server
  3. Under Automatic proxy setup — turn OFF Automatically detect settings
  4. Test connection
📌Also check your browser proxy settings: Chrome → Settings → System → Open your computer’s proxy settings — make sure everything is off.
10

Run SFC + DISM System File Repair

⏱ 15 min  |  🟡 Medium  |  Fixes deep system corruption

If nothing else works, corrupted Windows system files may be preventing DNS from working correctly. SFC and DISM repair these files automatically.

  1. Open Command Prompt as administrator
  2. Run SFC scan first:
// Step 1: System File Checker sfc /scannow
  1. Wait 10 minutes for it to complete
  2. Then run DISM repair:
// Step 2: DISM Image Repair DISM /Online /Cleanup-Image /RestoreHealth
  1. Restart PC after both complete
✅DISM needs internet to download repair files. Run it while connected via mobile hotspot if WiFi is completely down.

❓ Frequently Asked Questions

What causes DNS Server Not Responding in Windows 11?
The most common causes are: your ISP’s DNS server being down or overloaded, corrupted DNS cache on your PC, antivirus blocking DNS requests, or a corrupted TCP/IP stack after a Windows 11 update. Changing DNS to Google (8.8.8.8) and flushing the DNS cache fixes it for most users within 2 minutes.
Is it my router or my PC causing this DNS error?
Quick test: if your phone works on the same WiFi but your PC doesn't — it’s your PC. If no devices work — restart your router first. The Quick Diagnosis section at the top of this guide walks you through exactly how to identify which device is causing the problem.
What is the best DNS server for Windows 11 in 2026?
Cloudflare (1.1.1.1) is the fastest DNS server in the world and is completely free. Google DNS (8.8.8.8) is slightly slower but equally reliable and is the safest choice for beginners. Both are vastly better than most ISP DNS servers and will eliminate recurring DNS errors.
Why does DNS Server Not Responding keep coming back after every restart?
If the error returns after every restart, your ISP’s DNS server is chronically unreliable. The permanent solution is Fix 2 — change your DNS server to Google (8.8.8.8) or Cloudflare (1.1.1.1). This bypasses your ISP’s DNS completely and the error will never return.
How do I fix DNS Server Not Responding without any internet access?
Open Command Prompt as administrator and run: ipconfig /flushdns, then netsh winsock reset, then netsh int ip reset. Restart your PC. These commands work completely offline and fix the most common DNS configuration issues without needing any internet connection.
