Recently I moved a bunch of domains over to a new server. Three of the domains that were moved resolved right away. That means that everyone’s DNS servers were able to access the sites. The weirdness started when the other domains on the same server of the 3 resolved, didn’t resolve on Cogeco’s and Sympatico’s DNS servers.

So I wondered if there was a problem on our web server, but there wasn’t. As it turned out, it was easily rectified by doing a very simple procedure called a DNS flush.

Here is the procedure in a nutshell:

Before you do a DNS flush, first you need to see if it is the domain’s server issue or not and you do it by pinging the site that you can’t access like so:

• open a command prompt window by clicking the start button, scrolling to “run” and typing “cmd” in the box.
• In the command prompt window type “ping thedomainyouwant.com” (without the quotes)

If you see something like this then you know the server where the domain resides is ok and it is a DNS issue:

So to clear up a DNS problem you simply perform a DNS flush like so:
Open the command prompt and type:
ipconfig /flushdns

Done! Restart your browser and go to the sites that you couldn’t access and there’s a very good chance you’ll be able to access them again.

Happy Browsing!
