To understand this better, basically, RPC is an inter-process communication (IPC) method.
This is used by clients and servers for communication purposes. RPC is used by programs to execute programs on a server computer. The perfect example of this is Microsoft Outlook. You communicate with Microsoft Exchange Server using RPC.
This enables you to send and receive emails. When you use Microsoft Outlook to send emails, your computer sends a message to the server computer in an obscure coding.
The server responds to your computer with another message that contains the results of the executed program. This is all being carried at the backend of the running program.
Integral to this is the endpoint. The endpoint includes the name, port, or a group of ports on a computer that is monitored by the server for incoming client requests. This is a network-specific address to be precise.
The endpoint mapper is the part of the RPC subsystem that is responsible for dynamically assigning endpoints to the server. When this function fails it leads to error 1753 message display. It shows that RPC service is not available.
Error CausesThe error code 1753 indicating RPC endpoint mapper service failure is triggered due to multiple reasons. These include:
