We are in the process of decoming our 2003 domain controllers (don't get me started about our change control process).
Various higher ups have asked that we just shut down the domain controllers for 2 weeks to see what breaks before we demote them. I'm trying to come up with a list of unintended consequences of this approach rather than demote/repromote if needed.
Aside from replication errors, what other problems can I take back to them letting them know it's a bad idea.
