Event ID 6003 — DNS Server Zone Transfer

Applies To: Windows Server 2008 R2

Domain Name System (DNS) enhances fault tolerance and load balancing by providing for server redundancy. For any given zone, a DNS server can act as a primary master server, which is the authority for a zone, or as a secondary server, which obtains its zone data from the zone's primary master server or another secondary server. This process is known as zone transfer.
