The error code 0x00000421 is documented within Windows error references and relates to service management:

Meaning:

This error code translates to 1057 in decimal and maps to the error message “ERROR_INVALID_SERVICE_ACCOUNT” ([MS-ERREF]: Win32 Error Codes, https://learn.microsoft.com/en-us/openspecs/windows_protocols/ms-erref/18d8fbe8-a967-4f1c-ae50-99ca8e491d2d). It indicates an issue with the account configured to run a specific Windows service.

There are two main possibilities for this error:

  1. Invalid Account Name: The account name specified for the service might be incorrect, non-existent, or misspelled.

  2. Invalid Password: The password associated with the service account might be incorrect.

Troubleshooting Steps:

Here’s how you can address the “ERROR_INVALID_SERVICE_ACCOUNT” error:

  1. Verify Service Account Configuration:

    • Open the Services Management Console (Services.msc).
    • Locate the service that encountered the error.
    • Right-click on the service name and select “Properties.”
    • Navigate to the “Log On” tab.
    • Verify the following:
      • The account name is spelled correctly and exists on your system.
      • The password is accurate (consider password visibility options if needed).
      • The account has the necessary permissions to run the service. This typically involves “Log on as a service” rights.
  2. Check for Group Policy Restrictions (if applicable):

    • In some domain environments, Group Policy might restrict the service accounts that can be used. Consult your network administrator if you suspect this might be the case.
  3. System Restore (if applicable):

    • If the error started recently after a system change, consider using System Restore to revert your system to a known good state where the service account configuration was likely functional.
  4. Review Event Viewer (Informational):

    • The Windows Event Viewer might contain additional details about the service startup attempt and the specific account-related error. Look for entries related to the service name and the error code around the time the issue occurred.

Additional Tips:

  • If you’re unsure about the correct service account credentials or permissions, consult your system administrator or the application’s documentation for guidance.
  • Consider creating a system restore point before modifying service account configurations, especially in critical systems.

By following these steps and verifying the service account configuration, you should be able to resolve the “ERROR_INVALID_SERVICE_ACCOUNT” error and ensure the service can run successfully.
