This guide will show you how to flush your DNS Resolver Cache.
The reason for doing this may be because pages aren't loading, pages are half loading (missing things on the page) or you are unable to make and searches even when having internet access and Windows showing that you have internet access.
What does this do exactly?
The DNS (Domain Name System) holds all of the search querys from pages and cached web files, sometimes the DNS can get corrupted due to a bad entry, this can mean that you will have trouble loading pages etc.
The default DNS that you may be using now is your ISP's DNS Server, this server includes all of the web pages and web files for every website that you visit, think of it has the "dictionary" of the internet, without a DNS Server when you request something it won't know where to get it from.
The DNS server learns as a new page is loaded and found, if the server can't find the page then it will automatically download the page from the websites server and store it in it's cache. The DNS server is why pages load fast or slow, page load times are not always reliant on your 'actual' internet download and upload speeds, the DNS plays a part aswell and so you should never assume that it is "slow internet" that is the reason for pages loading slowly.
What do I have to do then?
It's fairly simple to flush the DNS Cache and there are no side affects or rather things that could go wrong from doing it.
Follow these steps.
1. Open a command prompt window (as an administrator). You can find the command prompt even in the accessories folder of the start menu or you can search "cmd.exe" (without the quotes) in the search field upon opening the start menu.
2. One the console is open you will need to type the following command > ipconfig /flushdns <
3. After typing the command in the window you can press enter on your keyboard, it will take maybe a millisecond before it is complete. Once it is complete it will tell you. You can then close the command prompt window.
4. You can then either open your internet browser and try loading pages again or restart the PC and then try loading pages again.
