The DNS Server role in Windows Server 2008 is redefiend via the below mentioed features:
Background zone loading: DNS servers that host large DNS zones that are stored in Active Directory Domain Services (AD DS) are able to respond to client queries more quickly when they restart because zone data is now loaded in the background.
IP version 6 (IPv6) support: The DNS Server service now fully supports the longer addresses of the IPv6 specification.
Support for read-only domain controllers (RODCs): The DNS Server role in Windows Server 2008 provides primary read-only zones on RODCs.
Global single names: The GlobalNames zone provides single-label name resolution for large enterprise networks that do not deploy Windows Internet Name Service (WINS). The GlobalNames zone is useful when using DNS name suffixes to provide single-label name resolution is not practical.
Global query block list: Clients of such protocols as the Web Proxy Auto-Discovery Protocol (WPAD) and the Intra-site Automatic Tunnel Addressing Protocol (ISATAP) that rely on DNS name resolution to resolve well-known host names are vulnerable to malicious users who use dynamic update to register host computers that pose as legitimate servers. The DNS Server role in Windows Server 2008 provides a global query block list that can help reduce this vulnerability.
