How to See and Flush the Contents of the DNS Resolver Cache in Vista
Information
  When you type a web address into your web browser and press ENTER, you are sending a query to a DNS (Domain Name System) server. If the query is successful, the website you want opens; if not, you'll see an error message. A record of these successful and unsuccessful queries is stored in a temporary storage location on your computer called the DNS cache. DNS always checks the cache before querying any DNS server, and if a record is found that matches the query, DNS uses that record instead of querying the server. This makes queries faster and decreases network and Internet traffic. IE7 has it's own DNS cache it manages, not including this one. For more detailed information, see: Windows Help and How-to: DNS (Domain Name System) FAQs
NOTE
  If the DNS Cache becomes corrupted, it can cause internet connection problems. Flushing the DNS Cache resets it clean.
WARNING
  If you disabled the DNS Client in Services, this tutorial will not work because the DNS Cache is disabled. To change the Service settings, see: How to Disable or Enable Vista Services with an Advice Guide
