A. To clear the DNS cache, perform the following steps:

  1. Start the Microsoft Management Console (MMC) DNS snap-in (Go to Start, Programs, Administrative Tools, and click DNS).
  2. From the View menu, select Advanced.
  3. Select and right-click the Cached Lookups tree node from the left-hand pane.
  4. Select Clear Cache from the context menu.

How to flush the DNS cache programatically?

(not using ipconfig/flushdns ?)
