1.6 Applicability Statement

This protocol applies to legacy clients that have to use RPC (as specified in [MS-RPCE]) to interact with a CA for the purpose of enrolling or managing X.509 (as specified in [X509]) certificates.

If clients can interact with the CA through Distributed Component Object Model (DCOM) (as specified in [MS-DCOM]) interfaces, they are to use the Windows Client Certificate Enrollment Protocol, as specified in [MS-WCCE].
