Error Code 0x80004805 Summary

The error code 0x80004805, also known as RPC_S_SERVER_UNAVAILABLE or ERROR_RPC_SERVER_UNAVAILABLE, typically indicates that a Remote Procedure Call (RPC) request was made to an unavailable server. This error can occur when attempting to access remote services, network shares, or specific applications that rely on RPC communication.

Description of Error Code 0x80004805 and Common Scenarios Where It Occurs

The 0x80004805 error can manifest in various scenarios involving Windows systems and services that use RPC, such as:

1. Windows Services: When trying to start or manage a service via the Service Control Manager (SCM) through remote management tools like PowerShell or WMI.
2. Network Shares: Attempting to map network drives or access shared resources on a machine that is not reachable due to network issues, hardware failure, or service unavailability on the target machine.
3. Remote Desktop: Connecting to remote machines over RDP when the RPC services are not running or have encountered an issue preventing normal operation.
4. Software Updates and Management Tools: Utilizing Microsoft System Center Configuration Manager (SCCM) or similar tools for software distribution, where communication with the server is blocked by network issues, firewall rules, or service downtime.
5. Printer Services: In scenarios involving remote printer management through RPC, when attempting to add a new printer or modify existing ones on a machine that has disabled or malfunctioning RPC services.

Note: These are just some common cases; the error can also appear in other contexts where RPC communication is required between two endpoints.

Howto solve error code 0x80004805

To resolve the 0x80004805 error, follow these steps:

  1. Check network connectivity to ensure that there is a stable connection between your machine and the remote server.
  2. Verify firewall settings on both local and remote machines to allow RPC traffic (ports TCP 135 and UDP 135).
  3. Restart the Remote Procedure Call (RPC) service on the affected machine. To do this, open Services management console (services.msc), locate ‘RPC Locator’ and ‘RPC Service’, right-click each to select ‘Restart’. If these services are not running, set their start type to Automatic.
  4. Run sfc /scannow in an elevated command prompt to check for file system corruption and repair it if possible. This command can help fix issues related to damaged or missing files that might cause RPC errors.
  5. Check the event viewer logs on both local and remote machines for any additional clues about what is causing RPC services to fail.
  6. If none of the above steps resolve the issue, you may need to reinstall or repair Windows Remote Management (WinRM) service which can sometimes be implicated in RPC errors. Use DISM /Online /Cleanup-Image /ScanHealth and /RestoreHealth commands to scan and restore WinRM.

Note: Depending on the specifics of your situation, it might also be necessary to check if other dependent services such as Windows Management Instrumentation (WMI) are functioning correctly.

If problems persist after attempting these solutions, consider reaching out for professional IT support or consulting more specific troubleshooting guides tailored to the exact circumstances causing RPC unavailability on your network infrastructure.
