Dhcp is not updating dns
I confirmed that my internet connection is working fine as I was able to go to google and look for search results.
The next step was to open these website with browsers such as IE, Firefox and Chrome.
The trick now, is to remove the global DNS and go back to select “obtain DNS server address automatically”. Switching between alternate DNS server address and automatic DNS server should fix the problem.
System restore feature enable you to restore your computer to a previous date and time when the computer was working fine.
Security software is another major culprit responsible for DNS Server Not Responding error.
Every security software tends to get corrupted over a period of time for reasons ranging from file corruption while updating files, conflicts with other software or indirect changes to security settings as a result of intentional or unintentional changes made on your PC.
