'The RPC server is unavailable' is a common error that can occur when using Outlook or any other Windows service on a shared network. While it may seem daunting to new users, it is typically a routine network error. In some cases, the issue is simply caused by the File and Printer Sharing feature being disabled on your system.
Nonetheless, there are various other factors that can result in an RPC Server error, which we will explore further in this section. First, let's provide a brief introduction to the RPC Server and explain why RPC Server errors occur. We will then delve into methods to resolve this common error.
The Remote Procedure Call, often abbreviated as RPC, is a network-based protocol that facilitates communication between various Windows processes through inter-process communication technology. RPC enables processes to efficiently share Windows-based resources within the same network. It operates as a request-response protocol and can be structured using a Client-Server communication model.
The RPC protocol enhances the ability of clients to securely connect with email servers. The following versions of Exchange Server and Outlook favor the use of RPC connections.
A user initiates a request, which is then transmitted to the server via RPC. In response, the server generates a response and sends it back to the user.
Note: Here, the client system and the server can either be different machines in a network or different processes within a single machine.
RPC plays a crucial role in managing devices across a network. Any disturbance caused within the network can result in RPC Server unavailable error.
There can be several reasons behind this error, but the most commonly reported one is improper configuration or disruptions in the connection of peripheral devices such as printers or scanners. Connection issues can often be resolved with a few simple steps.
In this section, we have listed some of the root causes that lead to the RPC Server is unavailable error.
