How To Promote Windows Server 2008 To Domain Controller
now browsing by tag
When a windows server family is freshly installed on a computer it first work as a client computer or a standalone server. When you have a standalone server you can promote it as a domain controller by installing Active Directory Services (ADS) or Active Directory Domain Services (AD DS) on a windows server 2003/2008 operating system respectively. By promoting a standalone server to a domain controller it then allows administrator to manage the entire network such as adding user accounts and client computers from a central location such as the windows server terminal.
If you work as a system administrator or a network administrator promoting a windows server machine is a common task.
Before Promoting Your Windows Server 2008
The server the administrator plan to promote must have a static IP address assigned to its Network Interface Card.
To begin promoting a computer with windows server 2008 installed to a domain controller.
Log in to Windows server 2008 with administrator account
Click on the Start Menu and type dcpromo on the Search box and press the enter key.
Wait for the Active Directory Domain Services Installation Wizard to load.
On the Operating System Compatibility window click on the next button.
Select Create a new domain in a new forest radio button if the computer your installing the Active Directory Domain Services is the only domain controller in the network or select Existing forest radio button if there are other domain controller in the network.
On the “Name the Forest Root Domain” type the name of the new domain in the text box and click on the next button.
On the “Set Forest Functional Level” leave the default value as is, click on the next button to continue.
On the “Set Domain Functional Level” leave the default value as is and click on the next button to continue.
On the “Additional Domain Controller Options” make sure that DNS server checkbox is checked, click on the next button continue.
If for instance you have not assigned a static IP address on your Network Interface Card you’ll be prompted with the Static IP Assignment message box. Click on “No, I will assign static IP addresses to all physical network adapter” to manually assign static IP address to all network card but you have to restart Active Directory Domain Services Installation Wizard again. If you have already assigned static IP to all the network interface card you will not be prompted with this message.
Click Yes button to continue when the DNS warning box appear.
Select Database location, log file, and SYSVOL folder location in the field or leave the default as is, I recommend leaving the default value as is.
On the “Directory Services Restore Mode Administrator Password” type in your desired password on the Password and Confirm password box and click on the Next button to continue. This password will be used for restoring the Active Directory from backup in case of disaster
