I installed Certificate Services in Enterprise CA mode on a domain memeber
server. Later, without making changes or issuing any certificates, I decided
to remove the installation and adopt a two tier method with an offline CA.
I've built and configured my offline CA and am preparing to build the
Enterprise CA again. I've noticed in Sites and Services under the Services
node and AIA container, that there are entries there with the name of my old
Enterprise CA server.

Can I safely remove these entries? Is there a method to clean up active
directory after a CA has been removed?
