To do this in Windows 10, follow these steps:

1. Open a different web browser, such as Google Chrome or Mozilla Firefox.
2. Enter the website URL in the address bar.
3. If the site loads successfully, it indicates that the issue may be with your original browser.

Using a different web browser can help identify whether the problem lies with your computer’s DNS settings or the browser itself. It’s a quick and easy troubleshooting step that can help resolve DNS errors.

python
import subprocess

def check_dns_server():
# Define the DNS server IP address
dns_server = '8.8.8.8'

# Execute a ping command to check if the DNS server responds
try:
output = subprocess.check_output(['ping', '-c', '1', dns_server]).decode('utf-8')
if '1 packets transmitted, 1 received' in output:
print(f"DNS server ({dns_server}) is responding.")
else:
print(f"DNS server ({dns_server}) is not responding.")
except subprocess.CalledProcessError:
print("Error: Failed to execute ping command.")

# Call the function to check the DNS server
check_dns_server()

This code uses the `subprocess` module to execute a ping command to the specified DNS server (in this case, Google’s public DNS server 8.8.8.8). If the DNS server responds and at least one packet is received, it prints a message indicating that the server is responding. Otherwise, it prints a message stating that the server is not responding.

Please note that this code only checks the responsiveness of the DNS server through a ping command, and it does not fix any potential issues.

Connecting with a Different Device

If you’re experiencing DNS Server Not Responding errors on your Windows 10 device, one possible solution is to connect with a different device. This can help determine whether the issue is specific to your device or if it’s a broader problem with your network or DNS server.
