Hi Patrick, I have enjoyed your videos. It would be great in the future if you did one on DR. e.g. 2 Domain controllers 01 and 02 and the first one fails (Permanently). What the process/options
would be. Thanks - Jason

Do you HAVE to do metadata clean up after? To avoid lingering objects.

Hi What if they are both GC Servers? or does it only matter that the DC I'm leaving is a GC Server?
