Domain Name Server (DNS Server) Features
The following are the features of DNS Server in Windows 2003.
1. Interoperability with other DNS servers.
DNS Server service in windows 2003 uses standard DNS data file and resource record formats, so that it can easily work with most of the other DNS server implementations. For example, The Berkeley Internet Name Domain (BIND) software.
2. Active Directory Domain Services(AD DS) support.
Windows 2003 supports (Active Directory Domain Services)AD DS integration with DNS to allow network systems to locate domain controllers and (Active Directory Domain Services)AD DS replication.
3. DNS zone storage enhancements in AD DS.
4. Conditional forwarders enhancement
In addition to the normal DNS Server forwarding functionality, conditional forwarding is implemented. In conditional forwarding, DNS server forwards DNS queries based on the DNS domain name in the DNS query.
For example, a DNS server can be configured to forward queries to a set of authoritative name servers based on the domain name suffix.
5. Stub zones
A stub zone is a copy of a DNS zone which contains the resource records necessary to identify the authoritative DNS servers for that zone.
A stub zone also keeps a DNS server of its parent zone. This helps to maintain the DNS name resolution efficiently.
6. Enhanced DNS security features.
DNS provides enhanced security for DNS Server, DNS Client service and for DNS data.
7. Integration with other Microsoft networking services.
The DNS Server service integrated with other services like AD DS, Windows Internet Name Service (WINS) and Dynamic Host Configuration Protocol (DHCP) services.
8. Improved ease of administration.
DNS Manager and Microsoft Management Console (MMC) offers an improved graphical user interface (GUI) for managing the DNS Server services.
9. Dynamic update protocol support
DNS enables DNS clients to update resource records dynamically. This removes the headache of manually adding resource record updates. Also DNS Client service can register their DNS names and IP addresses dynamically.
10. Support for incremental zone transfer between servers
DNS servers uses zone transfers to replicate information of DNS zone data which is in files. If the zones are not integrated with AD DS, then the DNS Server uses incremental zone transfer to replicate only the changed portions of a zone thus conserving network bandwidth.
11. Single-label host-name resolution without WINS
The DNS Server service supports GlobalNames zone to hold single-label names. In networks with no WINS, the GlobalNames zone provides single-label name resolution servers with fixed IP addresses.
