Windows 7 "Name Resolution Timed Out."

[srsozzu]

I'm getting this error in my event log every so often as my network connection crashes.

Name resolution for the name <www.XXX.com> timed out after none of the configured DNS servers responded.

I have to reset my network card (disable and then enable in Device Manager) in order to get a connection back. I have seen this issue in relation to Windows 7 on at least a dozen different forums now, and no one has a solution, which is ridiculous. It has nothing to do with our computers, everyone posting it has different network cards. It is obviously a Windows 7 issue.

- Someone suggested it was the Bonjour service for iTunes, this turned out not to be true.
- It only happens under heavier traffic, like when loading a lot of images or a YouTube video.
- The times it happens are completely random--I've gone without the issue for weeks, and it just started up again.

Has anyone had this problem and figured out how to stop their network connections from being randomly dropped?

The error you are encountering, where name resolution for a specific website times out after none of the configured DNS servers respond, can indeed be frustrating and disruptive to your network connection. This issue typically indicates a problem with DNS resolution on your system. Given the symptoms you described, here are a few troubleshooting steps you can try to resolve or mitigate this issue:

Troubleshooting Steps:​

1. Update Network Drivers:
   • Ensure that your network adapter drivers are up-to-date. Outdated drivers can sometimes cause network connectivity issues.
   []Reset TCP/IP Stack:
   • You can reset the TCP/IP stack to its default state. Open Command Prompt as administrator and run the following commands:

     shell netsh int ip reset netsh winsock reset

   []Change DNS Servers:
   • Try using alternative DNS servers like Google DNS (8.8.8.8 and 8.8.4.4) or OpenDNS (208.67.222.222 and 208.67.220.220) to see if the issue persists.
   []Check Firewall and Security Software:
   • Ensure that your firewall or security software is not blocking the DNS resolution for specific websites.
   []Check for Malware:
   • Run a scan with your antivirus software to check for any malware that might be affecting your network connection.
   []Disable Auto-Tuning:
   • Disabling TCP auto-tuning might help. Open Command Prompt as administrator and run:

     shell netsh int tcp set global autotuninglevel=disabled

   []Network Troubleshooter:
   • Windows has a built-in Network Troubleshooter that can help diagnose and fix network issues. You can access it by right-clicking on the network icon in the system tray and selecting "Troubleshoot problems".
2. Check Event Viewer for More Details:
   • Look in the Event Viewer for any related errors or warnings that might provide more information on the network connectivity issue. Please try these steps and see if they help in resolving the intermittent network connection drops you are experiencing. Remember to restart your system after making any changes for them to take effect.
