DNS is called as Domain Name System. The Domain Name System is a standard technology for managing names of sites and other Internet domains. DNS technology permits you to type names into your web browser like computer working and your computer to automatically find that address on the Internet. An important element of the Domain Name Server is a worldwide collection of DNS.What Is A DNS Server?A DNS server is any computer registered to connect the Domain Name System. DNS server’s runs special purpose networking software, features a public IP address, and enclose a database of network names and addresses for other Internet servers.DNS is like a phone book for the server. If you know a person’s name but don’t know telephone number, you can simply search it in a phone book. Domain Name Server provides this same service to the Internet. When it comes to talking on the Internet, computers don’t recognize each other by name. They prefer numbers, usually.It happens on a name server that holds a directory to transfer the name to number. The name server for this purpose is part of the Domain Name System, a distributed system that exists across the planet. It is one of the most important elements of the Internet as we know it now. Without DNS, we would certainly have to know all those numbers; it will be like trying to remember thousands of phone numbers just to search the web and emails.When you send out an appeal on the Internet to access a site, the appeal goes out over your network, and moves from router to the Internet. But it has to initial check in at a resolving Domain Name Server to see what the actual address is. The resolver could be at your Internet Service Provider, which makes it quick. But if it doesn’t know, the resolver will send the appeal to a root server that is part of the DNS.If the root server doesn’t know, it will tell the resolver to go talk to a zone server the Domain Name Server that knows all the top level domains. This could go on for a while, but ultimately a DNS name server should have the information you want.All that talk between resolver and name servers, plus the traffic to the Web server you wanted information from in the first place, happens in milliseconds. Just as quick, the final answer to your request like loading a web page is sent back to your home connection, to the router, to the home network, and ultimately back to your computer or phone. But in your web browser, all you ever saw was the name of the site.What’s really amazing is how the Domain Name Server is distributed across millions of servers on the Internet, yet to your PC, it all looks like one big database.How To Fix DNS Server Not Responding?Are you experiencing DNS errors when you try to load a website to your network?

To open your internet connections window, click the Start menu and search for “ncpa.cpl”.Search for extra connections.You can see a list of your connections. The most common cause for Domain Name Server problems is the existence of “Microsoft Virtual Wi-Fi Miniport Adapter”. IF you see this, right click it and select Disable.Flush your DNS.Sometimes your DNS cache gets expired and need to be manually flushed. This can be getting from the Command Prompt.
