3.4. Automating the Promotion or Demotion of a Domain Controller
You want to automate the installation or removal of a domain controller. You can make the promotion process part of your standard build process by incorporating the necessary configuration lines in your answer file(s).
You can automate the promotion of a domain controller by using the
unattended process when building the server or by manually running
dcpromo after the system has been built. Pass an
answer file containing the necessary lines to promote the server to
dcpromo by specifying a
switch. Here is an example:
> dcpromo /answer:
If you want to run
dcpromo as part of an
unattended setup, you need to add a
section in your unattended setup file that calls the
process. You can
promote a domain controller only after setup has completed and
someone logs in for the first time. That is why it is necessary to
[GUIRunOnce] section, which sets the
RunOnce registry key to kick off
dcpromo after someone logs in. Here is an example:
[GUIRunOnce] "dcpromo /answer:%systemroot%\system32\$winnt$.inf"
dcpromo answer section starts with
[DCInstall]. Here is an example answer file for
adding a domain controller to an existing domain in the rallencorp.com forest:
[DCINSTALL] UserName=administrator Password=RAllencorpAdminPassword UserDomain=rallencorp.com DatabasePath=%systemroot%\ntds LogPath=%systemroot%\ntds SYSVOLPath=%systemroot%\sysvol SafeModeAdminPassword=DSrestoreModePassword ...
