How To Fix RPC Server Unavailable Error ?

Have you gotten an RPC error lately? Something like these:

- "RPC Server is Unavailable"

- OR "The RPC Server is too busy to complete the task"

Unfortunately, an RPC error is one of the most common errors out there, and most of us don't even know what RPC is.

What is RPC?

RPC stands for "Remote Procedure Call." This probably still doesn't tell you much. Let's see if we can put this in non-technical language. RPC is the go between of your computer and server. This is what allows your computer to access a network.

RPC has two main parts to it: the client and the server. When the client (the program requesting something) sends a message to the server (the process that takes the order or performs the task), it is being asked to execute a certain procedure. The client waits for the server to process the call before resuming the execution.

Why Won't the RPC Server Work?

Usually, the RPC error pops up because there is some sort of miscommunication between the computer and the server. Most of the time, the wires get crossed somewhere due to Internet components that are not configured or activated. Sometimes it is just a matter of adjusting the Internet Firewalls or Proxy Server.
