Active Directory: a DCPromo answer file

This example shows how to provision an Active Directory domain from an answer file. The domain and domain controller role can be installed from a script, making the process repeatable. This script was generated for Windows Server 2003.

Create a DCPromo answer file

Copy the text below into a new text file named ad.txt.

[DCInstall]
AdministratorPassword =P@SSWORD1
CreateOrJoin = Create
DomainNetBiosName = 70-296
NewDomainDNSName = 70-296.net
RebootOnSuccess = Yes
ReplicaOrNewDomain = Domain
SiteName = "Default-First-Site"
InstallDNS=yes
ConfirmGc=Yes
TreeOrChild = Tree
UserName=Administrator
Password=P@SSWORD1

Change the administrator password and open a command prompt. Run dcpromo /answer:ad.txt. My answer file installs the DNS server automatically, so make sure the Windows Server source CD-ROM is available locally or in a CD drive.

After the reboot, I verified the domain installation.

Active Directory was installed successfully. The answer file lets me reproduce the steps in my lab and prepare for production deployments.
