Hi

If you're experiencing issues with resolving a domain name on Windows 11, but it can be pinged on Linux systems and accessed in browsers, there could be a few possible reasons for this discrepancy. Here are some steps you can take to troubleshoot and potentially resolve the issue:

Flush DNS Cache: Start by flushing the DNS cache on your Windows 11 system. Open the Command Prompt as an administrator and run the following command:

ipconfig /flushdns

1. Check Network Configuration: Ensure that your network configuration on Windows 11 is correct and properly configured. Double-check the DNS settings in your network adapter properties to ensure they are set correctly.
2. Disable IPv6 Temporarily: Temporarily disable IPv6 on your Windows 11 system to see if it resolves the issue. To do this, go to "Network and Internet Settings" in the Windows Settings, select your network connection, click on "Change adapter options," right-click on your network adapter, choose "Properties," and uncheck the "Internet Protocol Version 6 (TCP/IPv6)" option.
3. Update Network Drivers: Make sure your network drivers are up to date. Visit the manufacturer's website for your network adapter and download the latest drivers compatible with Windows 11.
4. Disable Firewall and Security Software: Temporarily disable any third-party firewall or security software on your Windows 11 system. Sometimes, these programs can interfere with DNS resolution. If disabling the software resolves the issue, you may need to reconfigure the settings or whitelist the affected domain.

Perform a Clean Boot: Perform a clean boot on your Windows 11 system to determine if any third-party applications or services are causing conflicts. Instructions for performing a clean boot can be found on the Microsoft support website.
