The Domain Name System (DNS) acts as the internet’s phonebook, translating human-readable website names (like www.google.com) into computer-readable IP addresses. When this system fails, your computer loses its ability to navigate the web. The good news is that the solution is often straightforward. Learning how to fix dns issues windows 10 is an empowering skill that can save you time, frustration, and money on tech support.

Understanding the Root of the Problem Before You Begin

Before diving into the fixes, it’s helpful to know what you’re dealing with. A DNS issue is not typically a problem with your internet service itself, but rather with the service your computer uses to look up website addresses. This can be caused by an overloaded or faulty DNS server from your Internet Service Provider (ISP), corrupted data stored on your own PC, or even interference from your security software. Knowing this context is the first step in understanding how to fix dns issues windows 10.

The Quickest Fix: Flushing Your DNS Cache

One of the most common and effective solutions involves clearing out the old, and possibly corrupted, DNS information stored on your computer. This is often the first real technical step anyone should take when figuring out how to fix dns issues windows 10. This process, known as flushing the DNS cache, forces your PC to get fresh, correct information.

Step-by-Step Guide to Flushing the DNS Cache

Press the Windows key on your keyboard, type “cmd”, and you will see “Command Prompt” appear in the search results.
Right-click on Command Prompt and select “Run as administrator.” This is crucial, as standard user privileges are not enough.
In the black Command Prompt window that appears, type the following command exactly as it is written and press Enter:
ipconfig /flushdns
If successful, you will see a message that says, “Successfully flushed the DNS Resolver Cache.”
Close the Command Prompt and try accessing the website again. This simple command is a cornerstone of learning how to fix dns issues windows 10.

Clear the cache, refresh your connection.

How to Fix DNS Issues Windows 10 by Changing Your DNS Server

Often, the DNS servers provided by your ISP can be slow, unreliable, or temporarily down. A powerful solution is to switch to a free, public DNS server. These services, offered by companies like Google and Cloudflare, are often faster and more secure. Manually configuring your DNS server is a highly effective method for how to fix dns issues windows 10.

Step-by-Step Guide to Changing Your DNS Server

Press the Windows key + R to open the Run dialog box. Type ncpa.cpl and press Enter. This will open the Network Connections window.
Right-click on the network connection you are currently using (it could be “Wi-Fi” or “Ethernet”) and select “Properties.”
In the list of items, find and select “Internet Protocol Version 4 (TCP/IPv4).” Click the “Properties” button.
In the new window, select the radio button that says “Use the following DNS server addresses.”
You can now enter the addresses of a public DNS server. Here are two of the most popular choices:
- Google Public DNS:
  - Preferred DNS server: 8.8.8.8
  - Alternate DNS server: 8.8.4.4
- Cloudflare DNS:
  - Preferred DNS server: 1.1.1.1
  - Alternate DNS server: 1.0.0.1
Enter your chosen addresses, click “OK” on both windows to save the changes, and then restart your browser. This is a fundamental skill for anyone wanting to know how to fix dns issues windows 10 for the long term.

Using More Powerful Commands: A Deeper Network Reset

If flushing the DNS wasn’t enough, you can use a series of more powerful commands to perform a deeper reset of your computer’s network settings. This process can resolve more stubborn corruption issues. These commands are an essential part of any advanced guide on how to fix dns issues windows 10.

Step-by-Step Guide to Resetting Network Protocols

Open Command Prompt as an administrator again.
Type the following commands one by one, pressing Enter after each command. Wait for each command to complete before typing the next one.
- ipconfig /release
- ipconfig /renew
- netsh winsock reset
- netsh int ip reset
After you have run all of these commands, you must restart your computer. This is not an optional step; the reset will not be complete until you reboot. This series of commands is a robust solution for how to fix dns issues windows 10.

Checking Your Network Drivers

Your network adapter driver is the critical piece of software that allows Windows to communicate with your physical Wi-Fi or Ethernet hardware. If this driver is outdated or corrupted, it can cause a wide range of network problems, including DNS failures. Ensuring your drivers are up to date is a key maintenance step and a valid approach for how to fix dns issues windows 10.

How to Update Network Drivers

Right-click the Start button and select Device Manager.
Expand the “Network adapters” category.
Right-click on your active network adapter and choose “Update driver.”
Select “Search automatically for drivers” and let Windows look for an update. If it finds one, follow the instructions to install it. If not, you may need to visit your computer manufacturer’s website to download the latest driver manually. Learning this process is vital for how to fix dns issues windows 10.

How to Fix DNS Issues Windows 10 with Advanced Methods

If you’ve tried all the steps above and are still facing problems, there are a few more advanced troubleshooting techniques you can use.

Temporarily Disable Your Firewall and Antivirus

Sometimes, third-party security software can be overly protective and interfere with network communications.

Try temporarily disabling your firewall and antivirus programs.
Check if you can now access the internet. If you can, you have found the source of the problem.
You will need to go into the settings of your security software to add an exception or “whitelist” your network activities.
Crucially, remember to re-enable your security software immediately after testing. This check is a valid part of the diagnostic process for how to fix dns issues windows 10.

Disable the IPv6 Protocol

While IPv6 is the future of the internet, it can sometimes cause conflicts on networks that don’t fully support it. Disabling it can sometimes resolve DNS issues.

Open the Network Connections window again (ncpa.cpl).
Right-click your active connection and select “Properties.”
In the list, find “Internet Protocol Version 6 (TCP/IPv6)” and uncheck the box next to it.
Click “OK” and restart your computer. Knowing when to try this is part of understanding how to fix dns issues windows 10.

Check the Hosts File

The hosts file is a system file that can be used to manually map domain names to IP addresses. In rare cases, malware can modify this file to redirect your traffic or block sites.

Open Notepad as an administrator.
Go to File > Open and navigate to C:\Windows\System32\drivers\etc.
Change the file type dropdown from “Text Documents (*.txt)” to “All Files.”
Open the file named “hosts.”
Look for any entries below the lines that start with a # symbol. Unless you have put them there yourself for a specific reason, any other entries could be suspicious and should be deleted. Proper knowledge of this file is an expert-level skill for how to fix dns issues windows 10.

The Final Software Step: Using the Network Reset Feature

Windows 10 has a “nuclear option” for network problems called Network Reset. This will completely remove and then reinstall all of your network adapters and reset all networking components back to their factory defaults. This should be used as a last resort.

Go to Settings > Network & Internet > Status.
Scroll to the bottom and click on “Network reset.”
Read the warning carefully. This will require you to restart your PC and may require you to reinstall VPN software or other networking tools.
Click “Reset now.” Your PC will restart after a few minutes. This is the ultimate built-in tool for how to fix dns issues windows 10.
