Resolved: Troubleshooting and Fixing the 0x80004012 Access Denied Error in Windows

Error Code 0x80004012 Summary: General Access Denied Error

The error code 0x80004012, also known as RPC\_E\_SERVERCALL_RETRYLATER in the Windows operating system, typically indicates a problem with remote procedure call (RPC) services. This issue can arise when there’s an unexpected disconnect between two applications trying to communicate through RPC, often due to network issues, software conflicts, or insufficient resources on either end of the connection. The error is commonly seen during setup and configuration phases involving Microsoft Office products or while installing certain updates or applications that rely heavily on networking services. It signifies that the server was unable to complete a requested operation within the specified time limit, usually due to temporary unavailability or resource constraints.

In Various Windows Applications and Services During Installation or Configuration Processes

The 0x80004012 error can occur in various scenarios where RPC communication is involved, such as:

During Windows Update installation: If the system attempts to download and install updates while experiencing network issues or server overload, it may encounter this error.
Office product installation: When installing Microsoft Office applications like Word, Excel, etc., if there’s a problem establishing an RPC connection with Microsoft servers for license validation or other setup-related tasks, this error can appear.
Windows Store app installations: Attempting to install apps from the Windows Store might lead to this issue if there is network instability or issues connecting to Microsoft’s update servers.
RPC-based software applications: If a third-party application relies on RPC services for communication and encounters difficulties establishing a connection, it can throw this error code.
Network configuration errors: Misconfigured firewalls, routing tables, or DNS settings that block or redirect necessary RPC traffic might also trigger 0x80004012.

To address the error and ensure successful completion of tasks like installing updates or software:

  1. Check your network connection and try to resolve any issues preventing stable communication with remote servers. If possible, connect directly to the internet via Ethernet instead of Wi-Fi.
  2. Restart your computer to refresh system settings and free up resources that might be causing temporary overloads or conflicts.
  3. Run a virus scan using an updated antivirus program to eliminate malware which may interfere with network communications.
  4. Open Windows Services and check the status of RPC services (RPC Locator, Distributed Transaction Coordinator). Restart them if they are stopped.
  5. Use Group Policy Editor (gpedit.msc) or Local Security Policy (secpol.msc) to adjust security settings related to remote access and RPC, ensuring that necessary protocols aren’t blocked by policy rules.
  6. If the problem persists after these steps, try reinstalling problematic software from scratch. Uninstall completely before downloading fresh installation files from official sources.

Howto solve error code 0x80004012

The error code 0x80004012 typically occurs due to network connectivity issues or misconfigurations affecting RPC services crucial for certain tasks such as installing updates or office products, running windows store applications, and other software relying on remote communication protocols. To solve this issue effectively, start by ensuring a stable internet connection, restarting your device, scanning for malware, and verifying that essential RPC-related services are enabled and functioning correctly within Windows Services. Additionally, review security policies through Group Policy Editor or Local Security Policy to make sure they aren’t inadvertently restricting necessary network traffic. If problems continue despite these measures, consider reinstalling affected software after a thorough cleanup of existing installations.
