Introduction
Here in this topic or article it is mentioned about the new method and process of installing and removing AD DS Windows Server 2008.
There is new installation of AD DS in Windows Server 2008. But where there are no new installations options available for AD DS in Microsoft Windows Server 2008 R2. In MS Windows Server 2008 R2 has new Domain and Forest Functional Levels which you can choose during or after an AD DS installation.
The location of Adprep.exe is completely different both in Windows Server 2008 and Windows Server 2008 R2. Always remember that before adding a domain controller that runs Windows Server 2008 or Windows Server 2008 R2 to an existing Windows 2000 Server or Windows Server 2003 Active Directory environment run Adprep.exe first is mandatory. The Windows Server 2008 operating system installation disk keeps the Adprep.exe file in /Sources/adprep folder, but in Windows Server 2008 R2, Adprep.exe is located in the /Support/adprep folder.
Both 32-Bit and 64-Bit version of Adprep.exe is included in Windows Server 2008 R2. Where 64-bit version runs by default. But make sure that if you are running 32 bit computer then always try to run a 32-bit version of Adprep.exe (Adprep32.exe).
* The new installation options are as given below:-
o RODC option.
o DNS option.
o New options in the Active Directory Domain Services Installation Wizard.
o New unattended installation options.
o Global catalog server option (GCS).
* New installation options of Windows Server 2008 is as mentioned below:
o Full installation of Windows Server 2008 or Windows Server 2008 R2
o Server Core installation of Windows Server 2008 or Windows Server 2008 R2
* Windows Server 2008 R2 includes Active Directory Administrative Center, which provides an enhanced Active Directory data management experience and a rich graphical user interface (GUI). Active Directory Administrative Center relies on Active Directory Web Services (ADWS), which requires TCP port 9389 to be open.
New AD DS installation Wizard
To add the AD Ds server role interactively, you can use the Active Directory Domain Services Installation Wizard. You can access the Active Directory Domain Services Installation Wizard in new ways, as follows:
* You can use the Add Roles Wizard in the following ways:-
o Click on Add Roles in Initial Configuration Tasks, then the application that appears when you first install the operating system.
o Then after that click on Add Roles in Server Manager, which is integrated with the Administrative Tools menu.
To install AD DS, you must run Dcpromo.exe. The process of installing AD DS by using dcpromo.exe, you can follow the given steps or methods.
Click Start, then select Run, and then type dcpromo, and then click OK, to proceed, as in previous versions of the Windows Server operating system.
The Installation Wizard of Active Directory Domain Services contains a new option on the Welcome page of the wizard to enable advanced mode as an alternative to running dcpromo with the /adv switch (dcpromo /adv). Advanced mode contains additional options that enable more advanced configurations.
The additional installation options in advanced mode include the following:
* Creating a new domain tree.
* Install from Media (IFM), in which you use backup media from an existing domain controller in the same domain or you create installation media by running the ntdsutil ifm command on a domain controller that runs Windows Server 2008 or Windows Server 2008 R2. You can then point to the installation media during the installation of AD DS to reduce network traffic that is associated with initial replication.
* Selecting the source domain controller for the installation. This enables you to control which domain controller is used to initially replicate domain data to the new domain controller.
* Modifying the NetBIOS name that the wizard generates by default.
* Defining the Password Replication Policy (PRP) for an RODC.
RODC option
RODC is the new in Windows Server 2008 where in Windows server 2003 PDC is used. Where an RODC hosts read-only partitions of the AD DS database. RODC is also used in remote location or remote server to deploye domain controller easily where the physical security requirements of a writable domain controller cannot be met.
New server operating system installation Winzards
There are two types of installation wizard in Windows Server 2008 and 2008 R2 is called a Server Core installation, in addition to the full installation. Both of these two installation process are as mentioned below.
1. 1. Full installation
Windows Server 2008 Full Installation Wizard supports both interactive and unattended Domain Controller installation.
1. 2. Server Core installation
A Server Core installation of Windows Server 2008 or Windows Server 2008 R2 mean that it uses a specific server roles, which reduces servicing and management requirements and the attack surface for those server roles. In this sense, “minimal” refers to the low use of memory and disk space by the Server Core installation.
To install AD DS on a Server Core installation, perform an unattended installation. A Server Core installation supports the following server roles:
* Active Directory Domain Services (AD DS)
* Active Directory Lightweight Directory Services (AD LDS)
* Dynamic Host Configuration Protocol (DHCP) Server
* DNS Server
* File Services
* Print Services
* Streaming Media Services
* Web Services (without ASP.NET on a server running a Server Core installation of Windows Server 2008 but with ASP.NET on a server running a Server Core installation of Windows Server 2008 R2)
