For those of you running Windows Vista, to get this method to work, you need to run the command prompt menu as an administrator. You do this by right clicking on the command prompt icon, and then selecting “Run as Administrator” from the list. Then just follow the steps in the article above, and it will take care of the problem.

try /ipconfig /all /dnsflush
should work just fine afterwards.

and i checked my dns client service was running and fine….everything is fine but still my internet connectivity is not working ..even though after running the above command i tried repairing my connection and im not getting dns error anymore but still internet connectivity is not working…any reason? is it because i updated my windows last night? sp3 is the source of problem ?any reply will highly be appreciated, thanks in advanced and yes my NIC card is working fine since im connected to linksys router via ethernet cable 100mbs

Same problem… ipconfig/flushdns and ipconfig/displaydns neither one work and cannot connect to the internet… windows connection detection says something about the firewall and the firewall is disabled.. the internet worked just fine yesterday and all I did was turn it on today only to find it won’t connect to http https and ftp
