FRS_ERR_CHILD_TO_PARENT_COMM - 8011 (0x1F4B)

The file replication service cannot communicate with the file replication service on the domain controller. The event log may have more information.

Updated: Feb 21, 2026

Technical Meaning

The FRS_ERR_CHILD_TO_PARENT_COMM error code indicates that the file replication service is unable to establish or maintain communication with another instance of the same service running on a domain controller. This can occur during various operations involving file replication, such as synchronization between servers.

Error Details

When this error occurs, it suggests that there might be an issue with network connectivity, configuration settings, or operational parameters affecting the ability to communicate between the two services. The event log may provide additional details regarding the specific circumstances under which the error was generated.

Usage Context

This error is typically encountered in environments where file replication services are configured across multiple domain controllers for redundancy and data synchronization purposes. It can also appear during troubleshooting or maintenance activities involving these services.

Developer Interpretation

Developers should interpret this error as an indication that the communication channel between the child service (likely a local instance of the file replication service) and its parent service (the domain controller's instance) is not functioning correctly. This could be due to network issues, misconfigured settings, or operational parameters that do not align with expected values.

Related Errors

  • FRS_ERR_CHILD_TO_PARENT_CONNECT: Suggests a failure to establish a connection between services.
  • FRS_ERR_CHILD_TO_PARENT_DATA: Implies issues with data transmission or processing during communication.

FAQ

Q: What does FRS_ERR_CHILD_TO_PARENT_COMM mean?

A: It indicates that the file replication service cannot communicate properly with its counterpart on a domain controller. This can be due to network problems, configuration errors, or operational parameter mismatches.

Q: How can I resolve this error?

A: Review network connectivity and ensure proper configuration of both services. Check for any misconfigured parameters that might affect communication.

Summary

The FRS_ERR_CHILD_TO_PARENT_COMM error code is a specific indication of communication issues between file replication services on different domain controllers. Developers should focus on verifying network settings, service configurations, and operational parameters to resolve this issue.
