How do I fix a DNS Server?

Question

I was using my computer but when I opened up a new tab to look something up it said Internet Explorer could not display the webpage. When I clicked diagnose problems it then told my my DNS server wasn't working. What is a DNS server and how do I fix it?

Answer 1

DNS is the PC converter that converts a site name to an IP address. If you get this type of message the problem is the site and not your PC.



Google DNS.

Answer 2

a DNS Server is a service server that is answers your requests for websites for example:

when you type www.google.com you are asking your DNS supplier (your ISP) what is the address for google and it gives you something called the IP Address.



but it doesn't sound to me as a DNS problem; because you said you opened a new tab which means that only one page didn't open.

So in my opinion the internet on your computer might have stopped for a sec and made your windows think that its a DNS resolving problem.

what you should do is restart your computer, if it didn't work for you should call your ISP (internet service provider) and tell them what you are facing.



another option could be that your country blocked this page for a reason therefore your ISP wouldn't give you its address.

Answer 3

a DNS server converts a website between its IP Address (209.85.175.99) and its hostname (google.com). try typing that number in your address bar and see if google loads. if it DOES, then your DNS settings may be wrong on your Network Interface Card (or your modem or router, if you have one).



unless your ISP specifies (or unless you are using Static IPs) your DNS settings should be set to Automatic. to see what they are now, click Start, and type:

cmd



and click ENTER. then type:

ipconfig /all



[note the space]

then hit ENTER. your DNS setting should be somewhere in the middle of all that other mess of numbers. if it is blank, or not what you ISP says it should be, you might need to call them to find out what it should be, although sometimes just restarting the computer fixes everything ;)

Answer 4

The lack of DNS is just the first indicator or loss of network connectivity. So I would try and ping a known ip, like 4.2.2.1 (sprint) and see if it responds. If it doesn't, then it is your ISP, modem or router. I'd hook up a device on ethernet to rule out wireless. Do you have integrated modem/router or a separate modem?
