Hello Rachel S,


The Domain Name System (DNS) is used to locate the IP address of a specific website domain name. It creates web browsing possible, specifically with over a billion websites on the Internet.

However, there might be circumstances when the system cannot locate the IP address, resulting in an ERR_NAME_NOT_RESOLVED DNS error. There are several possible causes, but the "ERR_NAME_NOT_RESOLVED" error occurs when a browser can't locate the IP address that hosts the domain name you wish to visit. Here are some possible causes for the error to occur,

• Cached data
• Network settings
• Enabled DNSSEC
• Antivirus software misconfiguration or Firewall.
• Browser settings.

Thus, In order to fix the error, you can follow the steps below,

Flush DNS Cache from Device:

• Firstly, use the Windows + R keys to open the Run dialog.
• Now, type cmd to open Command Prompt.
• Then, type the following commands and press Enter,

ipconfig /flushdns
ipconfig /registerdns
ipconfig /renew
ipconfig /release

• Lastly, It automatically clears your DNS cache files and resets the DNS resolver cache.

Clear Host Cache from Google Chrome Browser:

• Firstly, open Google Chrome, type chrome://net-internals/#dns on the browser's search bar, and press Enter.
• Lastly, click on Clear host cache.

Reset your Windows Firewall and DNS Server Addresses:

• Firstly, press the Windows + R keys to launch the Run dialog.
• Then, type firewall.cpl and click on the OK button.
• Now, click on the Restore defaults option in the left-side menu.
• Lastly, click the Restore defaults button to reset your firewall's original settings.
• Firstly, open the Control Panel.
• Then, navigate to Network and Internet > Network and Sharing Center.
• Now, click on Change Adapter Settings.
• Next, right-click the network adapter you use to connect to the Internet, then select Properties.
• Then, double-click Internet Protocol Version 4 (TCP/IPv4) or Internet Protocol Version 6 (TCP/IPv6).
• Lastly, enter the public DNS server address for the preferred and alternate DNS servers.

However, If the issue persists, you can try the below ways to fix the "ERR_NAME_NOT_RESOLVED" error.

1. Reset the Winsock catalog
2. Scan your computer for malware
3. Temporarily disable your Antivirus.

I hope the ways mentioned above help you to resolve the DNS "ERR_NAME_NOT_RESOLVED" error.
