How to Fix DNS Client Not Restarting Error on Windows 11: Step-by-Step Solutions

Experiencing issues with the DNS Client service not restarting on Windows 11 can disrupt your internet connectivity. This problem often prevents your system from resolving domain names properly, leading to browsing difficulties. Fortunately, there are several simple steps you can follow to fix this error.

The solutions range from basic service restarts to more involved system troubleshooting. Each method is designed to help you get the DNS Client service running smoothly again. No technical expertise is required, as all steps are explained clearly and in detail.

By following this guide carefully, you will learn how to identify common causes and apply fixes to restore your network functionality quickly. Let’s begin with some quick preliminary checks before diving into the solutions.

These instructions work specifically for Windows 11 but may also help users on other Windows versions experiencing similar issues.

Quick Note: Prerequisites and Preliminary Checks

Before starting with the troubleshooting steps, make sure to perform these quick checks. They can save you time and avoid unnecessary complications.

  • Check your internet connection: Verify that your device is connected to the internet via Wi-Fi or Ethernet. Sometimes, the problem might be with the network itself.
  • Restart your computer: A simple reboot can often fix minor glitches affecting services like the DNS Client.
  • Ensure you have administrative privileges: To restart services or change system settings, you need to be logged in as an administrator.
  • Update Windows 11: Keeping your system updated can fix bugs that cause service errors.

Step 1: Restart the DNS Client Service Manually

The DNS Client service is responsible for resolving domain names into IP addresses. Sometimes, it might stop working or fail to restart automatically. Manually restarting this service can fix temporary issues.

  1. Press Windows + R keys to open the Run dialog box.
  2. Type services.msc and press Enter. This opens the Services window.
  3. Scroll down and find DNS Client in the list.
  4. Right-click on DNS Client and select Restart. If the option is greyed out, select Start instead.
  5. Wait a few seconds for the service to restart, then check if your internet connection is working properly.

This step is important because restarting the service refreshes its operation and can fix temporary faults without further intervention.

Step 2: Clear DNS Cache

Sometimes, corrupted DNS cache can cause the DNS Client service to misbehave. Clearing the cache forces your system to fetch fresh DNS information.

  1. Press Windows + S and type Command Prompt.
  2. Right-click on Command Prompt and select Run as administrator.
  3. In the command window, type the following command and press Enter:
ipconfig /flushdns

You should see a message saying “Successfully flushed the DNS Resolver Cache.”

After this, try to restart the DNS Client service again using Step 1 or check if the issue is resolved.

Step 3: Check for Dependency Services

The DNS Client service depends on other essential Windows components. If any of these are stopped or malfunctioning, the DNS Client may fail to start.

  1. Open the Services window again by pressing Windows + R, typing services.msc, and pressing Enter.
  2. Find and check the status of these services:
    • Remote Procedure Call (RPC)
    • TCP/IP NetBIOS Helper
    • DHCP Client
  3. Ensure all of these services are set to Running. If not, right-click and select Start.
  4. After confirming these dependencies are running, try restarting the DNS Client again.

These services support network communication and are critical for DNS Client operation. Ensuring they work correctly can resolve many service start failures.

Step 4: Reset TCP/IP Stack

If network settings are corrupted, resetting the TCP/IP stack can help restore proper communication channels used by DNS services.

  1. Open Command Prompt as an administrator (see Step 2).
  2. Type the following commands one by one, pressing Enter after each:
netsh int ip reset
netsh winsock reset

These commands reset your network protocols to default settings, which can remove any problematic configurations.

After running the commands, restart your computer and check if the DNS Client service starts correctly.

Step 5: Modify DNS Client Service Settings

If the DNS Client service still refuses to restart, adjusting its startup type can sometimes help.

  1. Open the Services window (services.msc).
  2. Locate DNS Client and right-click to select Properties.
  3. In the General tab, find the Startup type dropdown menu.
  4. Change it to Automatic (Delayed Start).
  5. Click Apply and then OK.
  6. Restart your computer and see if the issue is resolved.

This setting delays the startup of the service, allowing other critical services to initialize first, which can prevent conflicts.

Alternative Method: Using System File Checker (SFC)

Sometimes, system files related to the DNS Client service may become corrupted. Running the System File Checker can repair these files.

  1. Open Command Prompt as administrator.
  2. Type the following command and press Enter:
sfc /scannow

This scan will check system files and automatically fix any issues detected. It may take some time to complete.

After the scan finishes, restart your computer and check the DNS Client service status.

FAQs

Why is the DNS Client service important?

The DNS Client service translates domain names like “www.example.com” into IP addresses. Without it, your browser cannot find websites properly.

Can I disable the DNS Client service?

Disabling the DNS Client is not recommended, as it can cause network problems and slow down your internet experience.

What causes the DNS Client service to fail?

Common causes include corrupted system files, network configuration errors, dependency service failures, or malware interference.

Will resetting the TCP/IP stack affect my network settings?

Resetting TCP/IP returns network settings to default, which may remove custom configurations like static IP addresses. Make sure to note your settings before proceeding.

Is it safe to run the System File Checker?

Yes, SFC is a built-in Windows tool designed to safely scan and repair system files without affecting personal data.

When Nothing Works

If none of the above steps resolve the DNS Client not restarting error, consider these final options:

  • Perform a Windows Update: Sometimes, installing the latest patches fixes system bugs that affect services.
  • Run Windows Network Troubleshooter: Go to Settings > Network & Internet > Advanced network settings > Network troubleshooter to let Windows diagnose and fix common problems.
  • Scan for Malware: Use a trusted antivirus tool to ensure no malicious software is interfering with system services.
  • Contact Microsoft Support: Visit the official Microsoft Support for professional help.
  • Consider System Restore: If the problem started recently, restoring your system to an earlier point might fix the issue.

Conclusion

Fixing the DNS Client not restarting error on Windows 11 is achievable by following a systematic approach. Starting with simple service restarts and cache clearing, you can often resolve the problem quickly. Checking dependencies and resetting network settings address more complex issues, while tools like SFC repair corrupted files.

Remember to proceed step-by-step, verifying the effect of each action before moving on. If problems persist, advanced options and official support provide further assistance. By understanding the role of the DNS Client and how it interacts with other services, you can maintain a stable and reliable internet connection on your Windows 11 device.
