What is a DNS server?

[GloboTech]

Stephen gave a good explanation of what is a DNS server. If you’re having problem connecting to a website but still able to connect to other site, there’s a few thing you can check to pinpoint the problem. You can try pinging the site and see if you get an answer from the remote server. You can also perform a “tracert” towards the hostname of the server and see the “road” the query takes to reach its destination. What OS are you using by the way ? Depending on what’s the issue, if you’re on windows, you can try running the following command in your “Command Prompt” (cmd) from your windows OS :

Ipconfig /flushdns

If the problem persists, please let me know what OS you use and what are the result of the ping or tracert you can explain a little bit more what's the issue exactly if it persists.
