Either the RPC service is not running, there are issues with the network, or some important registry entries that control the RPC service have been corrupted. On a Windows 10 machine, there are three basic potential causes for this error message. How to Fix ‘RPC server is unavailable’ Errors The whole process operates in reverse when the destination service or server has done its job and has data to send back to the initiating program.
It works a bit like networking in that the RPS server will open a port, communicate with the destination service or server, await a response, send a packet when it has a response, and then transfer the task data to the destination server or service. RPC is basically just a system that allows different processes to communicate with each other to perform a task. What makes things a little confusing is that with modern PCs multitasking and running many programs at once, RPC has become a method that some applications use to communicate with other applications running on the same computer. RPC stands for “remote procedure call”, and it is a method that computers have used literally for decades to communicate with one another.
What is RPC?įirst, let’s talk about what RPC is in the first place to relieve some of the confusion and mystery. I’ll show you how to figure out both kinds of problems in this article. Most RPC server errors occur within one computer, but the cause of the problem can be something on that computer or something in the network as a whole. It’s a methodology, not a Windows-specific process. Although we are going to talk about RPCs in Windows systems in this article, you should be aware that the RPC methodology is used on just about every kind of computer system in use today.
