The main focus here is centered on main issues related with the deployment of windows server 2008 in an enterprise environment. Before embarking on such a deployment it is important to choose the right version of the Windows 2008 primarily based on such factors like hardware compatibility, pricing as well as capabilities of various features in the application. The major versions of Windows Server 2008 include; Windows Web Server 2008, Windows Server 2008 Standard, Windows Server 2008 Enterprise and Windows Server 2008 Datacenter each of which comes with both the 32-bit and 64-bit editions. An important feature in Windows Server 2008 is related with the server core. This is basically a stripped version of the operating system without graphical user interface elements such as the desktop, taskbar or explorer window. Rather the server core it exhibits a command prompt window aimed at executing server related instructions. The main purpose of the server core is to improve performance of the server, overall security as well as the reliability of the entire system.

In order to deploy Windows Server 2008 in a large enterprise network, it is essential to perform a hardware inventory in order to asses their appropriateness to the performance of the operating system. To simplify the inventory process it is paramount to install Microsoft Assessment and Planning Solution Accelerator (MAP). MAP collects hardware profiles from all machines in the network domain and then generates a comprehensive report from all the machines. MAP does this through the assessment wizard which identifies the machines in which Windows Server 2008 can be deployed. The assessment report gives the administrator the right information and the go ahead to deploy the server system. This is best done using the Windows Deployment Services (WDS) which is a "role included with the Widows Server 2008." (Microsoft Official Academic Course, 2009) This way it is possible to deploy Windows Server 2008 on remote computers without any dedicated supervision. The WDS allows the administrator to install and configure all features of Windows 2008 server such as Active Directory, Dynamic Host Configuration Protocol and Domain Name Service among others.

Chapter 2 - Planning Infrastructure Services

Infrastructure services are a combination of applications which run in the background to facilitate the execution of core network related operations. Major services include Dynamic Host Configuration Protocol (DHCP) and Domain Name System (DNS). DCHP is used to manage Internet protocol (IP) addresses as well as TCP/IP settings. Windows Server 2008 DCHP Server service is used to manage network clients in a large enterprise network. Because of the large nature of enterprise networks it is essential to deploy the DHCP server either in a distributed system or in a centralized infrastructure or a combination of both.

The DNS is used to manage key elements in both the Internet and Active Directory services. It is important to understand the DNS structure together with the various communication channels between a client and server in order to come up with a good DNS deployment plan. DNS is also useful in management of internet domains and sub domains. Deploying the DNS server requires no more than just the use of DNS Server role on a computer running Windows Server 2008.

Chapter 3 - Planning an Active Directory Deployment

Active Directory is a key component of Windows Server 2008 which is aimed at managing both hardware and software resources as well as providing authentication and authorization mechanisms to network users. Active Directory is a service that is implemented on the domain level in order to improve scalability and efficiency. Closely related to a domain is an organizational unit which helps in management of resources although it does not offer security policies. Further elements in Active Directory structure include s objects, sites, trees and eventually forests. In addition a domain controller is sued to implement Active Directory services.

The standard communication protocol for Active Directory is known as Lightweight Directory Access Protocol (LDAP). Prior to deploying Active Directory, it is important to design the domain space while putting into consideration the structure of the organization. The installation of an Active Directory Domain Services role forms the basis of the deployment process. Additionally it is essential to come up with a comprehensive Group Policy in order to populate the entire network with core settings.

Chapter 4 - Planning Application Services

An application service is basically an application which performs a specific function and mostly resides on the server. Application services can be categorized as being client based, server based or distributed. An application server is used to implement the functionality of application services. Basic services include file, print, web, media, and terminal and even fax services. It is important to choose the right kind of a computer which will be able to guarantee security, fault tolerance, scalability and availability.

Windows 2008 Server incorporates two mechanisms to install application services; Group Policies and System Center Tools. Terminal services form an important part of Windows Server 2008 deployment. Specifically Remote Desktop Protocol and Remote Desktop Connection Client forms good management features in a network domain. Equally important is Web Services (IIS) which help in the management of web pages and related internet resources. In order to enhance the performance of these services, it is vital to have the necessary hardware resources which will guarantee performance and reliability.
