Updated: Feb 21, 2026
Technical Meaning
The error code RPC_S_NO_BINDINGS with the numeric value 1718 and hex code 0x6B6 indicates that there are no bindings available for the requested operation. This typically occurs in scenarios where a client application attempts to make a remote procedure call (RPC) but cannot establish a connection due to missing or unavailable bindings.
Error Details
This error is returned by the Windows Remote Procedure Call (RPC) runtime library when it fails to find any valid bindings for the service being requested. Bindings are essential in RPC as they define how and where the remote procedure call should be routed, including the protocol and endpoint information.
Usage Context
The RPC_S_NO_BINDINGS error is commonly encountered in distributed applications that rely on RPC for communication between client and server components. It can occur when:
- The application attempts to make an RPC call but no bindings are configured or available.
- There is a misconfiguration in the RPC service setup, such as missing or incorrect binding information.
- Network issues prevent the establishment of necessary connections.
Developer Interpretation
When encountering RPC_S_NO_BINDINGS, developers should consider several aspects:
- Verify that all required bindings are correctly configured and available for use.
- Ensure that network connectivity is established between the client and server components.
- Check if there are any configuration issues in the RPC service setup, such as missing or incorrect binding information.
