Certificate Enrollment Web Service Overview
The Certificate Enrollment Web Service is an Active Directory Certificate Services (AD CS)
role service that enables users and computers to perform certificate enrollment by using the
HTTPS protocol. Together with the Certificate Enrollment Policy Web Service, this enables
policy-based certificate enrollment when the client computer is not a member of a domain or
when a domain member is not connected to the domain.
Personal note:
Since domain controllers are off-limits (regarding open ports), you are left to install the
Certificate Enrollment Web Service role service on a plain member server
