I have a Windows Server 2003 R2 DC running a private forest. I have added a
Windows Server 2008 machine to the domain and want to promote it as a DC in
the existing forest. I added the Active Directory Domain Services role to
the server, and rebooted. It asks me to run "Active Directory Domain
Services Installation Wizard (dcpromo.exe)". As I step through this wizard,
I get an error:
---------------------------
Active Directory Domain Services Installation Wizard
---------------------------
To install a domain controller into this Active Directory forest, you must
first prepare the forest using "adprep /forestprep". The Adprep utility is
available on the Windows Server 2008 installation media in the
\sources\adprep folder.
---------------------------
OK
---------------------------
So I go to the media and run this command:
-------------- BEGIN --------------
Z:\sources\adprep>adprep /forestprep
Adprep cannot run on this platform because it is not an Active Directory
Domain Controller.
[Status/Consequence]
Adprep stopped without making any changes.
[User Action]
Run Adprep on a Active Directory Domain Controller.
-------------- END --------------
Oops, looks like I was supposed to run this on the currently active DC. So
I go over to the Server 2003 R2 DC and run adprep from it's media and it
seemingly succeeds:
-------------- BEGIN --------------
Z:\CMPNENTS\R2\ADPREP>adprep /forestprep
ADPREP WARNING:
Before running adprep, all Windows 2000 domain controllers in the forest
should be upgraded to Windows 2000 Service Pack 1 (SP1) with QFE 265089, or
to Windows 2000 SP2 (or later).
QFE 265089 (included in Windows 2000 SP2 and later) is required to prevent
potential domain controller corruption.
For more information about preparing your forest and domain see KB article
Q331161 at http://support.microsoft.com.
[User Action]
If ALL your existing Windows 2000 domain controllers meet this requirement,
type C and then press ENTER to continue. Otherwise, type any other key and
press ENTER to quit.

-------------- END --------------
Returning back to the Server 2008 machine, and running the wizard again I
still get this error:
---------------------------
Active Directory Domain Services Installation Wizard
---------------------------
To install a domain controller into this Active Directory forest, you must
first prepare the forest using "adprep /forestprep". The Adprep utility is
available on the Windows Server 2008 installation media in the

---------------------------
OK
---------------------------
But I just did this. I only have one DC in the forest, so not sure what
else to do. I tried rebooting the Server 2008 machine, etc, and nothing
works.
Anybody know what I might be missing here?
Thanks!
