Active Directory Installation with DNS and DHCP Configuration - Part 3

Here, we will look at the System configuration required for SCCM. This will include Active Directory installation, DNS and DHCP installation and configuration.

AD with DNS Installation

To configure Windows 2008 server for use as a Domain Controller, follow these steps:

1.  Click on Start > Run

2.  Type dcpromo > Click OK

3.  Next, the system will then check if the Active Directory Domain Services (AD DS) binaries are installed; if they are not already present, it will install them.

4.  The Active Directory Domain Services Installation Wizard will start. If you are an expert or advanced user,check “Use advanced mode installation”, otherwise just click Next

5.  The Operating System Compatibility page is displayed and this will brief the user about the improved security settings of Windows Server 2008. Click Next

6.  Since you are creating a new DC from scratch choose “Create a new domain in a new forest” and click “Next”.

7.  Enter the Fully Qualified Domain Name (FQDN) of the new forest root domain inside the textbox andclick “Next”

8.  If you selected “Use advanced mode installation” on the Welcome page, the Domain NetBIOS Name page will appear. On this page, type the NetBIOS name of the domain or accept the default name and then click next.

9.  Choose the type of Forest Functional Level and click “Next”.

Note: Functional level determines the features of Active Directory Domain Services (AD DS) that are enabled in a domain or forest. If you are creating a new domain or a new forest, the levels can be chosen to the highest values that the environment can support. E.g. If your environment supports both 2003 and 2008 server then you would choose Windows Server 2003 as your Forest Functional Level.

10.  If you chose Windows Server 2003 as Forest functional level, then you need to select the domain functional level in next screen. Select Windows Server 2003 and click “Next”.

11.  In the “Additional Domain Controller Options” page, select to install the domain Name Service (DNS) to your server.

Note: The First domain controller in a forest must be a Global Catalogue; that’s why the checkbox beside Global Catalogue is selected and can’t be unchecked. Also the first domain controller in a new forest or in a new domain cannot be a Read Only Domain Controller (RODC)

Select DNS Server and click next

12.  If static IP is not assigned to your server you will see the following screen.Now you need to assign static IP and start the above process.

13.   The Additional Domain Controller Wizard will now configure DNS. If the wizard cannot create a delegation for the DNS server, it will display a screen to create the delegation manually. To continue, click “Yes”.

14.   The next dialog box will ask where the domain controller database, log files and SYSVOL are stored on the server.

Note: The database folder stores information about the users, computers and other objects on the network.

The Log folder stores information related to AD DS such as an object being updated.

SYSVOL stores Group Policy objects and scripts. By default, SYSVOL is part of OS files in the Windows directory.

Accept the default settings and click next.

15.  In the Directory Services Restore Mode Administrator Password page, type a password then confirm it and click next.

Note: This password is used to start the Domain Controller in “Directory Services Restore Mode”.

16.    Next, the AD DS installation wizard summary page will be displayed. This is where you have the chance to review and maybe modify your settings. This screen also provides an option to Export Settings that can be saved in an answer file that can be used in an unattended operation.

Review the summaryand once you are happy,click “Next”

17.   DNS installations will then start.
