Rpc Server Is Unavailable
RPC is also known as Remote Procedure Call. It is a technology present since the emerging of computers and utilizes the interprocess communication technique. Its primary purpose is to enable a client and a server to communicate with each other over the network. Same can be said about devices. The RPC Server is Unavailable. RPC stands for Remote Procedure Call, which utilizes inter-processing communication technology for Windows processes within a network. RPC works on the basis of a client-server communication model, wherein client and server need not always be a different machine.

And according to some reports, when you want to sync the PC time when the internet time, the RPC server ceases to work. Now you can see the RPC can be inaccessible mostly upon you run a program on a network.To make things worse, Windows 10 backup failed because your PC runs into RPC server is unavailable 0x800706ba error code.Undoubtedly, you need to troubleshoot the RPC server not working as soon as possible. Prior to that, it is necessary to get the hang of the RPC and RPC server, thus you can better understand what causes the RPC server error. What is an RPC Server?RPC is the abbreviation for Remote Procedure Call, which is a protocol wherein a program can use a service of another program on another PC using a network without the need to know about this network in details.As it is well-known, RPC makes use of client-server mode or you can also call it request-response mode, in which request is raised by the process of the client, whereas the response comes from another process of the server. And in RPC, the Procedure Call encrypted originates from the Client process as well.Here an RPC server refers to a communication interface offered by a program to make it possible for remote clients to connect, pass commands, and transfer data using RPC protocol.In a word, RPC enables Windows 10 to set up communications between different applications on a single computer.
And you can simply regard the RPC as the application taking charge of remote devices through a network, like printers and scanners. Why Is RPC Server Unavailable on Windows 10?From the error description, you can get that the RPV server is not in place when a Procedure Call is requested on such peripherals as a scanner. Your printer stops working since it failed to connect to the network along with the client to respond to the request, thus leading to the RPC server unavailable.It is uncertain what is wrong in the whole process that blocks Windows 10 RPC server, but there are several potential culprits you can try to tackle. Probably your RPC service functions improperly, or the firewall blocks the RPC servers, or network runs incorrectly on Windows 10.Unfortunately, even when using the Remote Disk Management on a remote server, the RPC server is unavailable can appear on Windows 10.

Upon clicking OK, you will be able to see the RPC server unavailable on Windows 10 backup or domain controller has disappeared. Solution 3: Check Windows 10 Network ConnectionsFrom how RPC works on your PC, you should have known that it affords the communication between two processes on one computer by a network. No matter it is the requested sent or the response received, you must ensure the network works like a charm on Windows 10. Only in this way will the unavailable RPC server not pop up on Windows 10.1. Navigate to Start Settings Network & Internet.2.
Under Ethernet or WIFI, click Change adapter options.3. Right click the Ethernet or WIFI to open its Properties.4.
Then check both the box of Fire and Printer Sharing for Microsoft Networks and Internet Protocol Version 4.All network items configured rightly, Windows 10 would not fail to login in since the RPC server is not usable.Here you would better update the network driver in Device Manager or from the official site in case the network error results in unavailable RPC next time. Solution 4: Change RPC RegistryLastly, the RPC server is unavailable can also be caused by the corrupted RPC server registry on Windows 10.Although you are not advised to alter the registry, to get printers back to work or Windows 10 backup to resume again, adjusting Remote Procedure Call registry is inescapable.1.
Hit Windows + R the combination keys to activate the Run box and then input regedit in the box.2. In Registry Editor, go to HKEYLOCALMACHINESYSTEMCurrentControlSetservicesRpcSs.3. Then under RpcSs, on the right pane, make sure your PC has all the items as below.If there is any sub-item missing for your RpcSs registry, determine to reinstall Windows 10.4. Under RpcSs, right click Start to Modify its value.5.
Then change RpcSs Value data to 2.6. Go back to Registry Editor window, and then go as the path: HKEYLOCALMACHINESYSTEMCurrentControlSetservicesDcomLaunch.Similarly, on the right pane, double click Start to edit its value to 2 as well.7. Follow the same steps to make the Start value data to 2 for RpcEptMapper.8. Reboot Windows 10.At this moment, you will have changed all the RPC relevant registries on Windows 10.In doing so, the RPC server is unavailable will be removed when Windows 10 logins in.
IntroductionRemote Procedure Call (RPC) is an inter-process communication technique to allow client and server software to communicate on a network. The RPC protocol is based on a client/server model. The client makes a procedure call that appears to be local but isactually run on a remote computer. During this process, the procedure call arguments are bundled and passed through the network to the server. The arguments are then unpacked and run on the server. The result is again bundled and passed back to the client,where it is converted to a return value for the client's procedure call.RPC is used by several components in Windows Server, such as the File Replication Service (FRS), Active Directory Replication, Certificate services, DCOM, domain join, DCPromo and RDP, NLB and Cluster, Microsoft Operations Master, Exchange and SQL.
