Line 28:

The [[Local Security Authority Subsystem Service]] (LSASS), [[Session Manager]] (SMSS), and [[Service Control Manager]] all use (A)LPC ports directly to communicate with client processes. [[Winlogon]] and the [[Reference monitor|Security Reference Monitor]] use it to communicate with the LSASS process.

As mentioned, Microsoft RPC can use (A)LPC as a transport when the client and server are both on the same machine. Many services that are designed to communicate only on the local computer use (A)LPC as the only transport through RPC. The implementation of remote [[objectObject linkingLinking and embeddingEmbedding|OLE]] and [[Distributed Component Object Model|DCOM]] in many cases uses (A)LPC for local communication as well.
