How do i clear DNS resolver cache?
Fortunately, it is possible to clear out the local DNS cache in order to get around these types of problems. Windows XP comes with a useful command-line utility, ipconfig, which has a switch, flushdns, for removing the entries in the cache. Open a command prompt and enter “ipconfig /flushdns” (without quotes) and the cache will emptied. Personally, I find that it sometimes speeds up Internet browsing to do this flush even when there are no obvious error messages. If you are curious about the contents of the DNS cache, they can also be seen by using ipconfig. In this case open a command prompt and enter “ipconfig /displaydns”. If you are experiencing trouble connecting to a particular Web site, it may be useful to see if its URL is in the cache and what IP is being used.
