How to Fix DNS Server Not Responding Error
The internet has become an essential part of daily life, from work and education to entertainment. But sometimes, technical issues can disrupt this flow, and one common problem is the “DNS server not responding” error. This error prevents your computer or device from connecting to websites, leaving you frustrated and offline. Understanding how to fix DNS server not responding error is crucial to restore your connection and ensure smooth online browsing.
DNS, or Domain Name System, translates website names into IP addresses, allowing your browser to locate and load sites. When your DNS server fails, your browser cannot access websites, resulting in an error message. This problem can stem from various causes, including network issues, incorrect DNS settings, malware, or even temporary glitches in your internet service provider. Fortunately, there are multiple solutions to address this error.
Understanding the DNS Server Not Responding Error
Before diving into fixes, it’s important to understand why this error occurs. DNS issues can happen due to your computer, router, or internet service provider. Sometimes, temporary network problems can prevent your device from communicating with the DNS server. Incorrectly configured network settings or outdated drivers may also cause the error. Additionally, certain security software, such as firewalls or antivirus programs, can block DNS connections. By identifying the root cause, you can apply the most effective solution.
Basic Troubleshooting Steps
Starting with simple troubleshooting can often resolve the issue without complex interventions. First, check your physical connections. Ensure your Ethernet cable is securely plugged in or your Wi-Fi is stable. Restarting your router and computer can also eliminate temporary glitches that may cause the DNS error. These basic steps might seem simple, but they often restore connectivity quickly.
Another essential step is to check your internet connection. Open other devices to see if they can access the internet. If the problem persists across multiple devices, the issue might lie with your internet service provider. In such cases, contacting Dhanote Internet Services can help resolve broader network problems.
Changing Your DNS Server
One of the most effective ways to fix DNS server not responding error is to change your DNS server settings. By default, your internet service provider assigns a DNS server, but sometimes these servers are slow or unresponsive. Switching to a public DNS service like Google DNS or OpenDNS can improve performance and resolve the error.
To change your DNS settings on Windows, go to Control Panel, navigate to Network and Sharing Center, select your connection, and access its properties. Under Internet Protocol Version 4 (TCP/IPv4), select “Use the following DNS server addresses” and input the new DNS values. For Google DNS, use 8.8.8.8 and 8.8.4.4. Restart your computer to apply changes. Mac users can adjust DNS settings through System Preferences > Network > Advanced > DNS.
Updating Network Drivers
Outdated or corrupted network drivers can also cause DNS errors. Drivers control how your computer communicates with network devices, and outdated versions may fail to interact properly with DNS servers. To update drivers on Windows, open Device Manager, find your network adapter, right-click, and choose “Update driver.” Select “Search automatically for updated driver software” and follow the prompts. Regularly updating drivers ensures compatibility and can prevent DNS issues.
Flushing DNS Cache
Your computer stores DNS information in a cache to speed up website loading. Sometimes, this cache becomes outdated or corrupted, causing connectivity problems. Flushing the DNS cache forces your computer to fetch fresh DNS information from servers. On Windows, open Command Prompt as an administrator and type ipconfig /flushdns, then press Enter. Mac users can flush DNS through Terminal with the command sudo killall -HUP mDNSResponder. This simple step can resolve many DNS errors.
Disabling Firewall and Antivirus Temporarily
While security software protects your computer, it can sometimes interfere with DNS connections. Temporarily disabling your firewall or antivirus program can help identify whether they are causing the DNS server not responding error. Ensure you turn off security software only briefly and avoid visiting untrusted websites during this period. If disabling the software resolves the issue, adjust its settings or add exceptions to allow proper DNS communication.
Using Network Troubleshooter
Modern operating systems include built-in network troubleshooters that automatically detect and fix connectivity problems. On Windows, navigate to Settings > Network & Internet > Status > Network Troubleshooter. Follow the prompts to identify and repair DNS or network issues. This tool can be especially helpful for users who are not comfortable adjusting advanced network settings manually.
Resetting TCP/IP Settings
TCP/IP settings define how your computer communicates over the internet. Corrupted settings can lead to DNS errors. Resetting TCP/IP restores default configurations and often resolves network issues. On Windows, open Command Prompt as an administrator and type the following commands one by one: netsh int ip reset and netsh winsock reset. Restart your computer afterward to apply changes.
Checking Router Configuration
Sometimes the DNS server not responding error originates from the router itself. Access your router settings through its IP address, usually printed on the device. Check if the router’s DNS settings are correct or switch to a public DNS server. Restarting the router after making changes can refresh its connection to the internet and resolve the error.
Disabling IPv6
Certain networks and devices experience DNS issues due to IPv6 configuration. Disabling IPv6 can help fix the problem. On Windows, navigate to Control Panel > Network and Sharing Center > Change adapter settings. Right-click your active connection, select Properties, and uncheck “Internet Protocol Version 6 (TCP/IPv6).” Restart your computer and test your connection.
Contacting Your Internet Service Provider
If all else fails, the issue may lie with your internet service provider. They can check whether their DNS servers are operational and assist in resolving connectivity issues. Contacting support, such as Dhanote Internet Services, ensures expert assistance and may prevent recurring DNS errors.
Preventing DNS Server Errors
Preventing future DNS issues requires regular maintenance and best practices. Keep your network drivers updated, maintain a secure and malware-free system, and consider using reliable DNS servers. Avoid abrupt shutdowns or disconnections that may corrupt network settings. A stable and secure setup reduces the likelihood of encountering DNS errors.
The DNS server not responding error can be frustrating, but with the right approach, it is fixable. From basic troubleshooting and flushing DNS cache to changing servers and updating drivers, multiple solutions exist to restore internet connectivity. Regular maintenance, careful network configuration, and using reliable DNS services are key to preventing recurring errors.
Don’t let DNS problems disrupt your online activities. Apply these solutions to resolve issues quickly. For ongoing support and reliable internet service, reach out to Dhanote Internet Services and ensure smooth, uninterrupted browsing.
