How Do I Fix Device Detected or Resource DNS Server Is Not Responding?
When using the internet, you may encounter issues with the DNS (Domain Name System) server not responding. This can be frustrating as it prevents you from accessing websites and other online resources. However, there are several steps you can take to fix this problem and get back online quickly.
Step 1: Check Your Internet Connection
The first thing you should do is check your internet connection to ensure it is working properly. Make sure all cables are securely connected, and if you are using Wi-Fi, try connecting to a different network or restarting your router.
Step 2: Restart Your Device
If your internet connection is working fine but you are still experiencing DNS server issues, try restarting your device. Sometimes a simple restart can resolve temporary glitches and restore normal functionality.
Step 3: Flush DNS Cache
If restarting your device doesn’t solve the problem, you can try flushing the DNS cache. The DNS cache stores information about previously visited websites, and clearing it can sometimes resolve connectivity issues.
To flush the DNS cache on Windows:
- Open Command Prompt: Press Windows + R, type “cmd,” and press Enter.
- Type the following command: ipconfig /flushdns
- Press Enter: The command will execute, and the DNS cache will be cleared.
To flush the DNS cache on macOS:
- Open Terminal: Go to Applications > Utilities > Terminal.
- Type the following command: sudo dscacheutil -flushcache
- Press Enter: Enter your administrator password if prompted, and the DNS cache will be cleared.
Step 4: Change DNS Server
If flushing the DNS cache doesn’t resolve the issue, you can try changing your DNS server. By default, your device uses the DNS server provided by your internet service provider (ISP). However, using an alternative DNS server like Google Public DNS or OpenDNS can sometimes improve performance and reliability.
To change the DNS server on Windows:
- Open Network Connections: Right-click on the network icon in the system tray and select “Open Network & Internet Settings. “
- Select Your Connection Type: Click on “Change adapter options.
- Open Adapter Properties: Right-click on your active network connection and choose “Properties. “
- Select Internet Protocol Version 4 (TCP/IPv4): Double-click on it to open its properties.
- Select “Use the following DNS server addresses”:
- Preferred DNS Server: Enter the IP address of your preferred DNS server (e.g., 8.8.8 for Google Public DNS).
- Alternate DNS Server: Enter the IP address of an alternative DNS server (e.4.4 for Google Public DNS).
To change the DNS server on macOS:
- Open System Preferences: Click on the Apple menu and select “System Preferences.”
- Select Network: Click on the “Network” icon.
- Select Your Connection Type: Choose your active network connection from the list (e., Wi-Fi or Ethernet).
- Click Advanced: It’s located at the bottom-right corner of the window.
- Go to DNS: In the new window, click on the “DNS” tab.
- Add DNS Servers:
- + Button: Click on the “+” button at the bottom to add a new DNS server.
- Add DNS Server Addresses: Enter the IP addresses of your preferred and alternate DNS servers.
- Your preferred DNS server (e.8 for Google Public DNS)
- Your alternate DNS server (e.4 for Google Public DNS)
Step 5: Contact Your ISP
If none of the above steps resolve the issue, it’s possible that there is a problem with your internet service provider’s DNS servers. In this case, you should contact your ISP for assistance and let them know about your connectivity issues.
In conclusion, when encountering device detected or resource DNS server not responding errors, it’s important to check your internet connection, restart your device, flush the DNS cache, change your DNS server if necessary, and contact your ISP if the problem persists. By following these steps, you can troubleshoot and resolve DNS server issues effectively.
