RPC_S_CANT_CREATE_ENDPOINT - 1720 (0x6B8)

The endpoint cannot be created.

Updated: Feb 21, 2026

Technical Meaning

The RPC_S_CANT_CREATE_ENDPOINT error indicates that the system was unable to create an endpoint for a Remote Procedure Call (RPC) service provider. This error is specific to the context of RPC programming and network services.

Error Details

This error typically occurs when the application attempts to register or create an RPC endpoint, but fails due to limitations or constraints imposed by the operating system or the RPC runtime environment.

Common Causes

  • Unsupported Operation: The operation attempted is not supported by the current configuration of the RPC service provider.
  • Resource Limitations: The system may have reached a limit on the number of endpoints that can be created simultaneously.
  • Incorrect Usage Context: The application might be attempting to create an endpoint in an unsupported or incorrect context, such as during an inappropriate phase of the program execution.

Real-World Context

This error is commonly encountered when developing network applications using RPC for inter-process communication. It may also arise in scenarios where multiple services are trying to register endpoints simultaneously, leading to resource contention issues.

Is This Error Critical?

The criticality of this error depends on the application's requirements and the context in which it occurs. If an endpoint creation is essential for the operation of a service or application, then this error can be considered critical as it prevents normal operation.

How to Diagnose

To diagnose the issue, follow these steps:

  1. Review Operation Context: Ensure that the RPC service provider and the application are in the correct state before attempting endpoint creation.
  2. Validate Parameters: Check all parameters passed to the RPC functions for correctness and completeness.
  3. Confirm Object Types: Verify that the object types being used align with the requirements of the RPC service provider.
  4. Verify Input Data: Ensure that the input data is valid and does not contain any corruption or invalid values.
  5. Check Limits or Constraints: Confirm that the system has sufficient resources to create an additional endpoint, such as available handles or memory.

How to Resolve

To resolve this issue, consider the following steps:

  • Correct Parameter Usage: Ensure all parameters are correctly set and passed to the RPC functions.
  • Adjust Operation Context: If the operation context is incorrect, adjust it to a valid state before attempting endpoint creation again.
  • Restore Data: If data corruption is suspected, restore or reinitialize the necessary resources.
  • Retry Operation with Valid Inputs: Attempt to create the endpoint again using valid and properly formatted inputs.

Developer Notes

Developers should be aware that this error can occur due to various factors, including unsupported operations, resource limitations, and incorrect usage contexts. It is essential to handle such errors gracefully in application code to ensure robustness and reliability.

FAQ

Q: What does the error RPC_S_CANT_CREATE_ENDPOINT mean?

A: This error indicates that the system failed to create an RPC endpoint, which can be due to unsupported operations, resource limitations, or incorrect usage context.

Q: How can I prevent this error from occurring?

A: Ensure that all parameters are correctly set and passed to the RPC functions. Verify that the operation context is valid before attempting endpoint creation. Check for any resource limits and ensure that the system has sufficient resources to create an additional endpoint.

Summary

The RPC_S_CANT_CREATE_ENDPOINT error signifies a failure in creating an RPC endpoint, which can be due to various factors such as unsupported operations or resource limitations. Developers should handle this error by validating parameters, adjusting operation context, and ensuring that the system has sufficient resources for endpoint creation.
