Running adprep on your windows 2K domain controller
Firstly I suggest reading this by Daniel Petri.
Then when you realise that you cant get a 32bit copy of Windows 2008 R2 refer to the following gem from this far eastern (it looks like) TechNet document...
In Windows Server 2008 R2, Adprep is available in a 32-bit version and a 64-bit version. The 64-bit version runs by default. If you need to run Adprep on a 32-bit computer, run the 32-bit version (Adprep32.exe).
