If you’re encountering the error message “Windows cannot communicate with the device or resource (Primary DNS Server),” don’t worry. This is a common issue that can be easily resolved. In this article, we will guide you through the steps to fix this problem.

What is a DNS Server?

Before we delve into the solutions, let’s briefly understand what a DNS server is. DNS stands for Domain Name System, and it acts as a directory that translates domain names (like into IP addresses (such as that computers can understand.

A primary DNS server is the first point of contact when your computer tries to access a website. If your computer cannot communicate with this primary server, you won’t be able to access any websites.

Possible Causes for Windows Cannot Communicate With the Device or Resource

There can be several reasons why you are experiencing this issue:

  • Network Connection Problems: Your network connection may not be stable, or there may be issues with your router or modem.
  • Incorrect DNS Settings: Your computer might have incorrect DNS settings, causing it to fail in connecting to the primary DNS server.
  • DNS Server Issues: The primary DNS server itself might have problems or could be down temporarily.

Potential Solutions

Solution 1: Restart Your Router and Modem

The first solution you should try is restarting your router and modem. This simple step can often resolve network connection issues and refresh your device’s connection to the primary DNS server.

  1. Turn off your router and modem by unplugging them from the power source.
  2. Wait for about 30 seconds before plugging them back in.
  3. Power on your router and modem and wait for them to establish a stable connection.

After following these steps, check if the error message persists. If it does, proceed to the next solution.

Solution 2: Change DNS Settings

If restarting your router and modem didn’t resolve the issue, you can try changing your DNS settings manually. Here’s how:

  1. Open the Control Panel by searching for it in the Start menu or using the Windows key + X shortcut and selecting Control Panel from the menu.
  2. Navigate to “Network and Internet” > “Network and Sharing Center”.
  3. Click on “Change adapter settings” on the left-hand side of the window.
  4. Right-click on your network connection, usually labeled as “Ethernet” or “Wi-Fi,” and select “Properties.”
  5. In the Properties window, select “Internet Protocol Version 4 (TCP/IPv4)” and click on the “Properties” button below it.
  6. Select “Use the following DNS server addresses”:
    • Preferred DNS server: Enter a different DNS server address (e.g., Google’s public DNS: 8.8.8).
    • Alternate DNS server: Enter another DNS server address (e.4.4).
  7. Click “OK” to save the changes.

After changing the DNS settings, check if the error message disappears and you can access websites properly. If not, move on to the next solution.

Solution 3: Flush DNS and Renew IP

Flushing the DNS cache and renewing your IP address can help resolve issues related to DNS settings. Follow these steps:

  1. Open the Command Prompt by searching for it in the Start menu or using the Windows key + X shortcut and selecting “Command Prompt” or “Command Prompt (Admin)” from the menu.
  2. Type the following commands one by one, pressing Enter after each one:
    • ipconfig /flushdns
    • ipconfig /release
    • ipconfig /renew
  3. Wait for each command to complete before running the next one.
  4. Close the Command Prompt window.

Once you have completed these steps, check if you can connect to websites without encountering any errors.

In Conclusion

The error message “Windows cannot communicate with the device or resource (Primary DNS Server)” can be frustrating, but fortunately, there are several solutions available. By restarting your router and modem, changing your DNS settings, or flushing DNS and renewing your IP address, you can often resolve this issue and regain access to the internet.
