In Microsoft environment, DHCP that automagically updates the DNS entries for every new DHCP client in the network is not a problem, since every client is part of the Active Directory and every machine as by default the rights to “talk” to the DNS server and tell it which is the client’s new IP address and hostname.
With the coming of Windows Server 2008 Core, its time to go back to the good old days of command line. We can add the DNS Server role and add manage DNS Server including setting up Forward and Reverse Lookup zones from the command line.
The following procedure should help you to setup and Configure a DNS server in Windows Server 2008 & Windows Server 2008 Core installation:
Windows 2000 & Windows 2003 DNS Server Dynamic DNS update functionality enables DNS client computers to register and to dynamically update their resource records with a DNS server whenever changes occur. This reduces the requirement for manual administration of zone records, especially for clients that frequently move and use Dynamic Host Configuration Protocol (DHCP) to obtain an IP address.
We have already discussed about how to install windows server 2003 domain controller with DNS server setup and DHCP server setup.Now we are going to discuss one more important topic how to create reverse lookup zone.
DNS allows two main types of queries: forward lookups and reverse lookups. A forward lookup searches for an IP address based on a provided host name.
A reverse lookup performs the opposite. It queries DNS for a host name based on an IP address. For example, some e-mail servers perform a reverse DNS lookup on a sending mail server to determine that the host name offered by the remote mail server actually matches the IP address of the SMTP connection attempting to deliver the message.
Windows Server 2003 includes all the functionality customers expect from a mission critical Windows Server operating system, such as security, reliability, availability, and scalability. In addition, Microsoft has improved and extended the Windows server product family to enable organizations to experience the benefits of Microsoft .NET—a set of software for connecting information, people, systems, and devices.
