Windows 7 DNS Problem!! cant find way to fix it!

[Laptopman]

Hi it has been over a month since i got this problem on my computer, whenever i try to open internet explorer it says: Internet explorer cannot display the webpage. Like if i had no connection. If i try with fire fox just nothing will show and if i try with chrome it says this:

The server at Google can't be found, because the DNS lookup failed. DNS is the network service that translates a website's name to its Internet address. This error is most often caused by having no connection to the Internet or a misconfigured network. It can also be caused by an unresponsive DNS server or a firewall preventing Google Chrome from accessing the network.

The only way the internet is working now is if I use the internet explorer (64-bit) which is the one im on right now anything else is not working and its a problem because eventhough i can use internet 64 bit if i try to play a game or something that requires internet it says that i dont have internet connection when i clearly do. I have tried almost everything I've seen in different threads but still nothing, its been more than a month now!!! any help please? i dont know what else to do. Btw my other laptop which was working just fine just got the same problem like an hour ago i dont know whats causing this. Thanks.

It seems like you are experiencing connectivity issues on your Windows computer, where Internet Explorer shows the message "Internet Explorer cannot display the webpage," Firefox doesn't show anything, and Chrome displays a DNS lookup failed error. Additionally, only Internet Explorer 64-bit is able to access the internet, while other applications like games report no internet connection. Here are some steps you can take to troubleshoot and resolve this issue:

Troubleshooting Steps:​

1. Check Network Connectivity:
   • Ensure that your internet connection is working on other devices.
   • Verify that the network cables (if used) are properly connected and Wi-Fi is enabled if applicable.
   []Restart Router and Modem:
   • Power off your router and modem, wait for a minute, then power them back on.
   • This can help in refreshing the network connection and resolving temporary issues.
   []Flush DNS Cache:
   • Open Command Prompt as an administrator.
   • Type the following command and press Enter:

      ipconfig /flushdns

   • This command clears the DNS resolver cache and may help in fixing DNS-related issues.
   []Reset TCP/IP Stack:
   • In Command Prompt as an admin, run the following commands one by one, pressing Enter after each:

      netsh int ip reset netsh winsock reset

   • Restart your computer after running these commands.
   []Check Proxy Settings:
   • Open Internet Explorer, go to Tools > Internet Options > Connections tab > LAN settings.
   • Ensure that "Automatically detect settings" is checked and no proxy server is enabled unless required by your network.
   []Check Firewall Settings:
   • Temporarily disable your firewall to see if it's blocking the connection.
   • If you can access the internet with the firewall off, adjust its settings to allow the browsers and games to connect.
   []Update Network Drivers:
   • Ensure that your network adapter drivers are up to date. You can do this through Device Manager.
   []Perform a System Restore:
   • If the issue started recently, consider using System Restore to revert your system to a point where the internet connection was working correctly.
   []Run Network Troubleshooter:
   • Open Settings > Update & Security > Troubleshoot > Internet Connections.
   • Run the troubleshooter to identify and fix network issues automatically.

     Additional Notes:​

     • If the issue persists, consider running a full antivirus scan to rule out malware interference.
     • Ensure that your Windows system is up to date with the latest updates from Microsoft.
     These steps should help in resolving your connectivity issues on both your Windows computers. If the problem persists, feel free to provide more details for further assistance.
