RPC_S_WRONG_KIND_OF_BINDING - 1701 (0x6A5)

The binding handle is not the correct type.

Updated: Feb 21, 2026

Technical Meaning

The error code RPC_S_WRONG_KIND_OF_BINDING indicates that a binding handle used in Remote Procedure Call (RPC) operations is not the correct type for the operation being performed. This error typically arises when an application attempts to use an RPC binding handle intended for one type of service or protocol with another.

Error Details

This error code suggests that there was a mismatch between the expected and actual types of the binding handle. For example, if an application expects a TCP/IP binding but receives a named pipe binding, this error would be triggered.

Usage Context

The RPC_S_WRONG_KIND_OF_BINDING error is commonly encountered in scenarios where applications interact with RPC services or when using RPC APIs to manage remote procedure calls. It can occur during the initialization of an RPC client or server context, or when attempting to perform operations that require a specific type of binding handle.

Developer Interpretation

Developers should interpret this error as an indication that the application is attempting to use an incorrect binding handle for the intended operation. This could be due to several factors such as misconfiguration, misuse of API functions, or incorrect handling of RPC bindings in the codebase.

Related Errors

  • RPC_S_INVALID_BINDING (1702): Indicates that a binding handle is invalid and cannot be used.
  • RPC_S_NO_CONTEXT (1703): Suggests that no context exists for the specified binding handle, which could also indicate an incorrect type of binding.

Q: How can I resolve this issue?

A: Ensure that the correct type of binding handle is being used for the specific RPC operation. Verify the configuration and usage of API functions related to RPC bindings in your codebase.

Summary

The RPC_S_WRONG_KIND_OF_BINDING error code highlights a mismatch between expected and actual types of binding handles in RPC operations. Developers should ensure that they are using the correct type of binding handle for their specific use case to avoid this error.
