For quite a while, I have been using a tip from PC Magazine regarding speeding up internet browsing.  Here is the text from PCMag:

"Windows XP and Vista store the DNS information of Web sites you've visited, to reach those sites faster each time you access them. The cache sometimes gets corrupted or stores a lot of unusable data, and that leads to slower Internet response times"

"To clear the cache, start, run, type cmd (brings up command prompt window), ipconfig/flushdns.  The command purges the DNS cache and restores your Internet access speed."

This has worked repeatedly for a long time.  However, recently, at the command prompt window, when I type "ipconfig/flushdns" and hit enter, I get the following text:

          Windows IP Configuration
          Could not flush the DNS Resolver Cache: Function failed during execution.

Can anyone help with why this no longer works?  Thanks.
