DCPromo – How to Install Active Directory

You can watch the video on DCPromo or read the article that appears below the video.

DCPromo is the Active Directory Domain Services Installation Wizard, and it is an executable file which resides in the System32 folder in Windows. When you run DcPromo in the Windows ?run? box, it will run this executable. This is the easiest way to install Active Directory on Windows servers. Active Directory Domain Services is installed when you run DcPromo, which enables a server to work as a domain controller. To run properly, Active Directory Domain Services requires a DNS server to be installed on the network. If DNS is not available for name resolution, you will be prompted to install a DNS server while running DcPromo.

Installing Active Directory using DcPromo will apply only to the Windows 2008 server family and legacy Microsoft servers like Windows Server 2003.? DcPromo in Microsoft Windows Server 2012 is deprecated. If you run DcPromo under Microsoft Windows Server 2012 it will advise you to use Server Manager instead.

This demonstration I will install Active Directory on Microsoft Windows server 2008 R2, using the DcPromo executable.

Install Active Directory using DcPromo

First, locate and run DcPromo.? You can search for DcPromo in the Start Menu, or you can directly run DcPromo in the Windows ?run? box. Here we use Windows ?run? to open DcPromo.exe.

Simply press the Windows key and R key together, type ?dcpromo?, and hit enter.

In our example, we?re installing Active Directory services on the first domain controller in the environment. There is no existing forest in this network. We choose the ?Create a new domain in a new forest? option.

Next, you?re asked to provide a name for this new root domain. This will be the fully qualified domain.


Name the Active Directory Domain

Name your fully qualified domain name (FQDN) for the forest root domain



Then you need to set the forest functional level. The Wizard will display a description for each functional level, and this will help you to determine the correct level for your requirement. The higher the forest functional level, the more features available – So set it according to your network environment requirements. For example, if you select Windows 2000 Native as the forest functional level, all your domains must be Windows 2000 or above. In this demonstration, we select the Windows Server 2008 R2 functional level, and go ahead. Click Next.

It?s a good idea to have the DNS on the same server where the domain controller will be installed. The Wizard does this for you while completing this Active Directory Installation.? Click Next.


Additional Domain Controller Options

Select Additional Domain Controller Options such as DNS Server


If there is no Static IP already set up for the domain controller, you will be prompted to configure one.? If necessary, you can ignore this request for now by selecting the option to gain an IP address from the DHCP server. Otherwise, go ahead with the recommended action and set an IP for the computer and click ?Next?.

Active Directory Domain Services File Locations

Select the location for database, log files and SYSVOL


You?ll now be prompted for a password. This password is for Directory Service Restore – it is not the Domain Administrator password. This password will be required should you need to remove Active Directory from a server using DcPromo.
