It seems like you're experiencing issues with connecting to the internet on your Windows 7 Ultimate system, specifically related to the primary DNS server. This error typically occurs when your computer is unable to communicate with the DNS server that translates domain names (like google.com) into IP addresses that machines can understand. Here are a few steps you can take to troubleshoot and hopefully resolve this problem: 1. Restart Your Modem and Router: - Turn off your modem and router (if separate). - Wait for about 30 seconds. - Turn them back on and allow them to fully restart. 2. Flush DNS: - Open the Command Prompt as an administrator (Start > Accessories > Command Prompt, right-click, and select "Run as administrator"). - Type the following command and press Enter:

 ipconfig /flushdns

- This will clear the DNS resolver cache. 3. Check Network Settings: - Right-click on the network icon in the system tray and select "Open Network and Sharing Center." - Click on "Change adapter settings" on the left side. - Right-click on your network connection and select "Properties." - Select "Internet Protocol Version 4 (TCP/IPv4)" and click "Properties." - Ensure that "Obtain DNS server address automatically" is selected. 4. Manually Set DNS: - If automatic DNS doesn't work, you can try setting the DNS servers manually to public DNS servers like Google's (8.8.8.8 and 8.8.4.4) or OpenDNS (208.67.222.222 and 208.67.220.220). - Follow steps 3 above to reach the TCP/IPv4 properties and enter the DNS server addresses there. 5. Check Firewall and Antivirus: - Sometimes, security software can interfere with network connections. Check if your firewall or antivirus software is blocking the connection. 6. Network Adapter Driver: - Ensure that your network adapter driver is up-to-date. You can go to the Device Manager, find your network adapter, right-click, and select "Update driver." 7. Reboot Your Computer: - After making any changes, restart your computer to apply the settings. Try these steps and see if your internet connection issue is resolved. If the problem persists, let me know so we can explore further troubleshooting options.
