Hi J.R. Sitman,
How many DCs you have?
You can demote the server without replicating by this command. i.e.Force removal.
dcpromo /forceremoval

Open in new window

Shutdown this(problematic) server for couple of days and monitor. If everything goes well please start the server the server and remove without replicating.
After force removal do a cleanup.
