What is an RPC server?
An RPC server (Remote Procedure Call Server) is a network communication interface that simplifies remote connection and communication between systems in a client/server model.

It allows a client computer to request the execution of programs or services on a remote server as if they were local. The server, known as the RPC server, listens for requests from RPC clients and responds by executing the requested procedures and returning the results.
What does it do?
An RPC server receives calls from client applications and executes functions or procedures on their behalf. The client does not need to know the implementation details of the remote procedure - it simply sends a request and receives a result, abstracting the complexity of network communication.
What is it used for?
RPC is used in many enterprise environments for:
- Windows domain services such as Active Directory and group policy processing
- Microsoft Exchange Server communication
- SharePoint farm inter-server communication
- Distributed application architectures
If an RPC server is unavailable or unreachable, users may encounter errors such as The RPC server is unavailable, which typically indicates a network, firewall, or service issue.
