If you attempt something like
ipconfig /flushdns
in a command prompt (which surely you all do?) and get the mysterious message
The requested operation requires elevation.
then fret not. Find the command prompt in your start menu (you have it pinned for easy access of course?), right click and select 'Run as Administrator' (you are an administrator?). Then you are free to flush away. 'Begone outdated DNS records' I hear you cry.
