Introducing the Domain Name System (DNS)
The process of obtaining an IP address for a computer name (for example, “ComputerA”) is called name resolution. Using the Routing and Remote Access Service (RRAS)
The routing service included with Windows Server 2008 is better suited for a smaller network or one with a small amount of network traffic that needs to pass between subnets. Introducing Network Access Protection (NAP)

Network Access Protection is a new feature in Windows Server 2008 that allows network administrators to specify one or more policies that define the conditions under which network access will or will not be permitted.

Introducing TCP/IP Addressing
IPv4 addresses are commonly represented using what is called dotted-decimal notation, in which the decimal value of each byte is shown, using periods to separate the bytes. Introducing IP version 6 (IPv6)

IPv6 address notation is noticeably different from the dotted-decimal of IPv4, using eight groups of four hexadecimal digits, separated by colons. IPv6 includes a few other enhancements for performance and security. Notably, IP security through the use of IPSec is an integral part of IPv6, whereas it was an optional feature under IPv4 Configuring Basic Network Settings

As discussed in Lesson 1, each host on a TCP/IP network should be configured with a number of mandatory and optional configuration items, including: Subnet mask
Default gateway
DNS/WINS servers
If this system will be a DHCP server, you should set a static IP address, because that will be required when you try to set up the DHCP server role. A spanned volume is made up of free space from multiple physical disks. GPT (GUID Partition Table) – This partition style is recommended for disks larger than 2TB, or disks that are used in Itanium computers Configuring the DHCP Server Role

BOOTP, which is still in use today, enables a TCP/IP workstation to retrieve settings for all the configuration parameters it needs to run, including an IP address, a subnet mask, a default gateway, and Domain Name System (DNS) server addresses. In brief, DHCP provides four key benefits to those managing and maintaining a TCP/IP network: Centralized administration of IP configuration

Dynamic host configuration
Seamless IP host configuration
Flexibility and scalability.
DHCP client –a computer that obtains its configuration information from DHCP DHCPDISCOVER – Sent by clients via broadcast to locate a DHCP server. Per RFC 2131, the DHCPDISCOVER message may include options that suggest values for the network address and lease duration. In turn, each forward or revers lookup zone can be one of three types: Primary zone

Secondary zone
Stub zone
Reverse lookup zone – Most queries sent to a DNS server are forward queries; that is, they request an IP address based on a DNS name. DNS also provides a reverse lookup process, which enables a host to determine another host’s name based on its IP address. Benefiting from Fault Tolerance and Redundancy

Windows Server 2008 introduces the Read-Only Domain Controller (RODC), a domain controller that contains a copy of the ntds.dit file that cannot be modified and that does not replicate its changes to other domain controllers within Active Directory. Using Active Directory Naming Standards

LDAP refers to an object using its distinguished name (DN) , which references an object in the Active Directory directory structure using its entire hierarchical path, starting with the object itself and including all parent objects up to the root of the domain. Understanding the Requirements for Active Directory

The Active Directory Installation Wizard, dcpromo, will guide you through any of the following installation scenarios: Adding a domain controller to an existing environment
Creating an entirely new forest structure
Adding a child...
