 * 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&quot; or &quot;ADPREP.EXE is not a valid win32 application
