A. If you've configured the DNS server to forward requests for other zone resolutions, the server will cache the requests it finds so that it can speed other requests for the same DNS lookup. To view the contents of the DNS cache, perform the following steps:
- Start the Microsoft Management Console (MMC) DNS snap-in (Go to Start, Programs, Administrative Tools, and click DNS).
- From the View menu, select Advanced.
- Select the Cached Lookups tree node from the left-hand pane to display the top-level domains (e.g., com, net) under .(root). Expand any of these domains to view the cached DNS information (the actual records will appear in the right-hand pane).
This figure shows several second-level domains under com, including Microsoft, that show three alias records (e.g., www.microsoft.com actually points to www.microsoft.akadns.net).
