Title: How to Clear the DNS server name cache in Windows Server 2003

Objective: The objective of this demo is to teach you how to clear the DNS server name cache in Windows Server 2003. DNS queries resolve in a number of different ways. A client can sometimes answer a query locally using cached information obtained from a previous query. The DNS server can use its own cache of resource record information to answer a query. Cached resouce records (RRs) contain information obtained from DNS servers that are uthoritative for DNS domain names learned while making iterative queries to search and fully answer a recursive query performed on behalf of a client.Later, when other clients place new queries that request RR information matching cached RRs, the DNS server can use the cached RR information to answer them.
