Microsoft Support sent the following reply after I requested the KB recommended hotfix:
"I understand that you would like to obtain hotfix from Microsoft. Currently the hotfix described in 919151 is not available for 64 bit."
My problem is described in this KB article 919151 :
In a Microsoft Windows Server 2003 forest in which all domain controllers run only an x86-based version of Windows, you experience one of the following symptoms: . You cannot deploy a Windows Server 2003 R2 x64 Edition-based domain controller.
. You cannot deploy Windows Server 2003 R2 schema-dependent features.
When you try to run the the Adprep.exe tool, you may receive the following error message:
ADPREP.EXE is valid, but is for a machine type other than the current machine" or "ADPREP.EXE is not a valid win32 application
This problem occurs because the x86-based version of the Active Directory Preparation tool (Adprep.exe) is not included in the Windows Server 2003 R2 x64 Edition installation media.
To resolve this problem, submit a request to Microsoft Online Customer Services to obtain the hotfix. To submit an online request to obtain the hotfix, visit the following Microsoft Web site ...
My Question now:
Is there any way to promote my Windows Server 2003 R2 x64 Edition to a domain controller without this hotfix?
