Clearing your DNS cache can improve website loading times and resolve issues that prevent access to specific websites. Cached DNS entries can be cleared using the Windows Command Prompt.
Press Win-C to open the Charms Bar and type cmd into the Search bar. Right-click the Command Prompt icon and select Run as Administrator.
Type ipconfig /displaydns in the Command Prompt window to view list of DNS entries stored in cache.
Type ipconfig /flushdns to clear cache. Wait for the message "Successfully flushed the DNS Resolver Cache" to display. This can take several seconds, depending on the size of the cache.
Type ipconfig /displaydns once more to confirm that cached DNS entries are no longer listed.
