Question : Error 105 net::ERR_NAME_NOT_RESOLVED The server could not be found

After booting up, I can get to a web page but when I try to go to another I get the above error message in Google Chrome. This also happens, with similar error messages, on Firefox and Explorer.

Answer : Error 105 net::ERR_NAME_NOT_RESOLVED The server could not be found

Try ipconfig /flushdns the next time it happens.  It sounds like a bad entry in the DNS cache if you are still able to ping certain sites.
