What is RPC?
RPC stands for Remote Procedure Call, which utilize inter-process communication technology for the Windows network. RPC work on the basis of client-server communication model, where the client and server need not always be a different machine. RPC can also be used to set up communication between different processes on a single machine.

RPC is a type of request-response protocol, which can be easily explained by using the communication model client / server. For the purposes of this tutorial, the process of begging the request be referred to as "clients" and the process of responding back to the request as a "server." Do note that here the client or the server can be a different device within a network or system can be of different processes within a single system.

In RPC, calling the procedure initiated by the client system, which is encrypted and then sent to the server. The call is then decrypted by the server, and the response is sent back to the client. RPC plays an important role in managing devices remotely over the network and used to share access to peripherals such as printers and scanners. On a simple note, any Windows process that involves the distribution and sharing of data across the network typically uses RPC technology. Therefore, it is very common to meet "RPC Server unavailable" issue if you are a Windows user. long distance calls, however, is intermittent when it comes to performance and therefore difficult to track down.

The reason for the error RPC
File and printer sharing are turned off
This is the most common cause of the RPC error. When the call procedure or request made to a peripheral device such as a printer, a device must be enabled for RPC and must be connected to the network with a client for it to function. If there's something wrong here, RPC will stop functioning.

network connectivity problems
Since a remote procedure call depends on the network to function, lack of proper network connections may cause problems server unavailability. In such cases, the client fails to send a procedural call to the server so that the error "RPC Server unavailable".

a name resolution problem
When a client initiates a request, the request is sent to the server using the name, IP address, and the port address. If the name of an RPC server is mapped to the wrong IP address, it generates the client contacts the server that is incorrect and may cause RPC errors.

firewall
Third-party firewall or other security applications running on the server or on the client, sometimes it may block traffic from reaching its server on TCP port, resulting in disruption of RPC.

Registry corruption
RPC depends on a valid Windows registry to work. If one of these entries is modified incorrectly or becomes damaged, the RPC service is likely to stop functioning.

Dealing with RPC error
firewall monitoring
As mentioned earlier, an application firewall or other security-related running on the system can block traffic from RPC request. If you have a third-party firewall installed, try to configure it to allow incoming and outgoing connections for RPC and other applications you intend to use in RPC.

If you can not configure the firewall, try to turn off the feature for a while until the RPC have been successfully created. In this way, you can know whether
