How to Fix the RPC Server Is Unavailable Error on Windows 11

If you’re encountering the ‘RPC Server Is Unavailable’ error on your Windows 11 PC, it can prevent remote connections, file sharing, and other network services from working properly. This guide walks you through practical steps to diagnose and fix this issue, restoring your system’s functionality and ensuring smooth network operations. Before you start, ensure your Windows 11 system is up to date and you have administrator privileges.

What You’ll Need

  • Administrator access to your Windows 11 PC
  • Stable internet connection
  • Basic familiarity with Windows Settings and Services

Step-by-Step

  1. Check Network Connectivity: Ensure your PC is connected to the network properly. Test by browsing websites or pinging a known server. If network issues exist, resolve them first.
  2. Restart Windows RPC Services: Open the Services app by pressing Windows key + R, typing services.msc, and hitting Enter. Locate the following services:
    • Remote Procedure Call (RPC)
    • DCOM Server Process Launcher
    • RPC Endpoint Mapper

    Right-click each service, select Restart. If any are not running, choose Start.

  3. Ensure Services Are Set to Automatic: In the Services window, double-click each service and set the Startup type to Automatic. Click Apply and OK.
  4. Verify Firewall Settings: Open Windows Security from the Start menu, go to Firewall & network protection, then click Allow an app through firewall. Ensure that ‘Remote Assistance’ and ‘File and Printer Sharing’ are allowed through both private and public networks.
  5. Check Network Profile Settings: Go to Settings > Network & internet > Advanced network settings > Properties. Ensure your network profile is set to Private to enable network discovery and sharing.
  6. Disable IPv6 (Optional): Sometimes, IPv6 conflicts cause RPC errors. Navigate to Control Panel > Network and Internet > Network and Sharing Center. Click on your network, then select Properties. Uncheck Internet Protocol Version 6 (TCP/IPv6), click OK, then restart your PC.
  7. Run Network Troubleshooter: Go to Settings > System > Troubleshoot > Other troubleshooters. Select Network Adapter and click Run the troubleshooter. Follow prompts to detect and fix network issues.
  8. Update Windows and Network Drivers: Ensure your Windows 11 is fully updated via Settings > Windows Update. Also, update your network drivers through Device Manager: right-click Start, select Device Manager, expand Network adapters, right-click your adapter, choose Update driver.
  9. Check for Malware: Run a full system scan with Windows Security or your preferred antivirus to rule out malware interference with network services.
  10. Reset TCP/IP Stack: Open Command Prompt as administrator (search for ‘cmd’, right-click, select ‘Run as administrator’). Type the following commands one by one, pressing Enter after each:
    • netsh int ip reset
    • netsh winsock reset
    • ipconfig /flushdns

    Restart your PC afterward.

Common Mistakes

  • Ignoring to run Command Prompt as administrator, which is necessary for network resets.
  • Disabling essential services instead of restarting or setting them to automatic.
  • Forgetting to restart the PC after applying network or service changes.
  • Assuming the firewall is the cause without verifying its settings.
  • Skipping Windows updates, which can contain critical fixes for network issues.

Tips

  • Always back up your system or create a restore point before making significant changes.
  • Use the Windows Troubleshooter as a first step—it automates many fixes.
  • Ensure your network hardware (router, modem) is functioning correctly and restart if needed.
  • Check for Windows updates regularly to keep network components and security patches current.
  • If you’re on a corporate or managed network, consult your IT department before making changes.

Troubleshooting

If the above steps don’t resolve the ‘RPC Server Is Unavailable’ error, consider these additional troubleshooting tips:

  • Test on a Different Network: Connect your PC to another network to determine if the issue is network-specific.
  • Perform a Clean Boot: Disable all non-essential startup programs and services to identify conflicts. Instructions are available on Microsoft’s support site.
  • Check Event Viewer: Open Event Viewer (Windows key + R, type eventvwr.msc) and look under Windows Logs > System for RPC-related errors for clues.
  • Reset Network Settings: In Settings > Network & internet > Advanced network settings, click Network reset. This will reinstall network adapters and reset configurations. Be aware you’ll need to reconnect to Wi-Fi networks afterward.
  • Reinstall Network Drivers: In Device Manager, uninstall your network adapter, then restart your PC to reinstall drivers automatically or manually install the latest drivers from the manufacturer.
