Very nice article on DNS. Enjoyed how it goes beyond a simple "here is the command so get at it" style you get everyone else.

@ jrj

I had an extremely nasty version of the google redirect virus myself. I suggest doing a hard reset on your router and manually configure your computer's DNS to OpenDNS. That resolved my issue after about a month of redirects, drove me insane.

Hope this helps

Rebooting won't help if you are infected with some malware or virus. I currently have some form of the 'google redirect' virus which so far no one has been able to resolve (and I'm an IT guy and have been trying for more than a week now; calls to TrendMicro, web search, etc, all to no avail).

The 'temporary' fix is to flush my DNS cache after booting, which is a small annoyance compared to the rather huge annoyance of all my Google searches being redirected.

I learned about performing this task a couple of years ago. I don't recall exactly from who but I'm pretty sure it was through a Cnet TechRepublic post. They also specified to follow this procedure by typing in ipconfig /renew and running it directly after. Why is there no mention of that here. Is it not necassary to do that?

"ipconfig /renew" is unrelated to flushing your DNS. /renew typically follows a /release. /release says "I release the IP address you've given me, I don't need it any more", and /renew says "I'd like a new IP address assigned to me please." This is also often used when troubleshooting, but for other types of problems.

I scanned my pc with A-Squared (EMSI Software). Found the culprit and fixed the problem. Before that, I had Firefox3.0 installed. I enjoyed its speed. When I was backed to IE7, I encountered "time-out" error messages. Not to blame FF 3.0 though, but I just wonder.
