Forceful Removal of a Domain Controller

Know Your FSMO Locations

Make sure that the DC you are removing is not holding any of the FSMO Roles

Seizing FSMO Roles (The Last Resort)

If for what ever reason you can not do a clean transfer you will need to seize it

Do not put the Infrastructure Master (IM) role on the same domain controller as the Global Catalog server. If the Infrastructure Master runs on a GC server it will stop updating object information because it does not contain any references to objects that it does not hold. This is because a GC server holds a partial replica of every object in the forest.
