when running dcpromo it tells me i need to run adprep. i run adprep but it states it cannot run on this platform because it is not an active directory domain controller.
we have a primary dc running 08 - 2000 native function level; i'd like to set up a second server (08 r2)is as a secondary dc for fault tolerance.
based on the error, do i need to run adprep on the primary dc? if so, will that disrupt the network?
