Windows Operating System rely on a number processes to run in an efficient manner. Without these processes, you won’t be able to run any applications on your PC flawlessly. In Windows, for some processes to run efficiently, there is a need to exchange data between a client and the server.

As we have earlier mentioned in Windows Environment, for executing a service or process it’s imperative to exchange data between the client and server. And if the task is done successfully, then only a process or service can run on flawlessly. So basically we can say that RPC enables various Windows processes to communicate with each other.
But sometimes due to certain factors the communication between a server and the client gets interrupted and the error RPC server is Unavailable Error 0x800706BA pops-up. To elaborate, when the RPC Server fails to answer the client and the requested process cannot be executed the users receive the above mention error. Note that in order to run the Windows efficiently, it’s mandatory that the processes are running smoothly, and for running a process it’s smoothly it’s imperative that server and the client are able to exchange data successfully.
And if we talk about the factors which lead to this inconvenience, following are the possible culprits:
#. Network Connectivity Issues
