• Restart your router or modem
  
• Perform a network reset by opening Command Prompt as an administrator and typing netsh winsock reset, then press Enter

python
import json
import requests

# Example usage
rpc_data = perform_rpc_request()
if rpc_data is not None:
# Process the RPC response
print(json.dumps(rpc_data, indent=4))


In the code above, a function `perform_rpc_request()` is defined to make an RPC request to the specified endpoint. It uses the `requests` library to send an HTTP GET request and retrieve the response. If an exception occurs during the request (e.g., network failure, invalid endpoint), it catches the `requests.exceptions.RequestException` and handles the error accordingly.

Please note that this code assumes a basic RPC scenario with an HTTP-based endpoint. The actual implementation may vary depending on the specific RPC technology or framework being used.

Resolving RPC Unavailability

If you’re encountering the RPC Server Unavailable error on your Windows machine, there are a few steps you can take to fix it.

First, ensure that the RPC services are running on your device. To do this, press the Windows logo key and the R key on your keyboard simultaneously to open the Run dialog box. Type “services.msc” and hit Enter. In the Services window, locate the Remote Procedure Call (RPC) service and ensure it is running.

If the RPC service is running, check your DNS servers. Make sure they are configured correctly and are accessible. DNS issues can often cause RPC unavailability.

Next, check your TCP port settings. RPC uses specific TCP ports for communication. Ensure that these ports are open and not blocked by any firewall or security software.

If these steps don’t resolve the issue, consider reaching out to a Microsoft MVP or consulting Microsoft documentation for more advanced troubleshooting steps.

Introduction to RPC Service

RPC Service is an essential component in Windows that allows different programs on a network to communicate with each other. However, sometimes users may encounter the “RPC Server Unavailable” error, which can disrupt various operations on their machines.

To fix this error, there are a few steps you can follow:

1. Check if the RPC services are running: Open the Services console by pressing Windows + R, then type “services.msc” and hit Enter. Look for the “Remote Procedure Call (RPC)” and “RPC Endpoint Mapper” services. Ensure they are running and set to start automatically.

2. Restart the RPC services: If the services are already running, try restarting them. Right-click on each service, select “Restart,” and confirm any prompts.
