The “DNS Client” service is a crucial Windows component that caches Domain Name System (DNS) names and registers the full computer name for your computer. When this service stops responding, you will likely lose the ability to connect to the internet, experiencing errors like “Server DNS Address Could Not Be Found.”
Here is a comprehensive guide on how to troubleshoot and fix the “DNS Client” service when it is not responding. Method 1: Restart the DNS Client Service Via Command Prompt
Often, the easiest way to fix a frozen service is to force a restart. Since the Windows Services Manager sometimes greys out the restart options for the DNS Client, using an elevated Command Prompt is the most reliable method.
Press the Windows Key, type cmd, and select Run as administrator.
To stop the service, type the following command and press Enter:net stop dnscache
To start the service again, type the following command and press Enter:net start dnscache Method 2: Flush the DNS Cache and Reset Winsock
Accumulated, corrupt DNS cache files or a misconfigured network stack can cause the DNS Client service to hang. Flushing the cache and resetting the Windows Socket (Winsock) API catalog often clears these bottlenecks. Open Command Prompt as an administrator.
Run the following commands one by one, pressing Enter after each: ipconfig /flushdns (Clears the DNS cache)
ipconfig /registerdns (Refreshes DNS leases and re-registers DNS names) ipconfig /release (Releases your current IP address) ipconfig /renew (Renews your IP address) netsh winsock reset (Resets the network catalog) Restart your computer to apply the changes completely.
Method 3: Modify the Windows Registry (If Options are Greyed Out)
If the DNS Client service is stuck in a disabled state and the options to change it in services.msc are completely greyed out, you can force-enable it using the Windows Registry Editor.
Note: Back up your registry before making changes, as incorrect modifications can cause system instability. Press Windows Key + R, type regedit, and hit Enter.
Navigate to the following path in the left sidebar:HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Dnscache
Locate the registry key named Start on the right pane and double-click it.
Change the Value data to 2 (This sets the startup type to Automatic). Click OK, close the Registry Editor, and restart your PC. Method 4: Change Your DNS Server Settings
If your local DNS cache service is failing due to issues with your Internet Service Provider’s (ISP) default DNS servers, switching to public, highly reliable DNS servers like Google or Cloudflare can bypass the issue.
Press Windows Key + R, type ncpa.cpl, and press Enter to open Network Connections.
Right-click your active network adapter (Wi-Fi or Ethernet) and select Properties. Double-click on Internet Protocol Version 4 (TCP/IPv4).
Click the radio button next to Use the following DNS server addresses. Enter the following values for Google Public DNS: Preferred DNS server: 8.8.8.8 Alternate DNS server: 8.8.4.4
Alternatively, you can use Cloudflare DNS (1.1.1.1 and 1.0.0.1). Click OK to save and exit. Method 5: Run the Network Troubleshooter
Windows includes a built-in diagnostic tool specifically designed to find and automatically repair network configuration errors that might be blocking the DNS Client. Press Windows Key + I to open the Settings menu.
Go to System > Troubleshoot > Other troubleshooters (or Network & Internet > Network Troubleshooter on older Windows versions).
Find the Network and Internet (or Internet Connections) troubleshooter and click Run.
Follow the on-screen prompts and apply any recommended automated fixes. Final Thoughts
In most scenarios, a quick DNS flush or resetting the service via the Registry will instantly restore your internet connection. However, if the issue persists after trying these methods, consider updating your network adapter drivers or checking your system for malware, as malicious software often targets DNS settings to redirect traffic.
