I have a 2008 R2 DC that has been off line for several months. Was at an off site office. It has been shipped back to me. Being that this system has been off-line for a while, what would be the correct way to Demote\Remove this domain controller from the domain? The system does power on. Would it introduce and issues my putting it back online? Then doing a DC promo? Or Force Removal? It does not hold any FSMO roles.
Thank you
