RPC_S_NO_PROTSEQS_REGISTERED - 1714 (0x6B2)
No protocol sequences have been registered.
Updated: Feb 21, 2026
Introduction
The error code RPC_S_NO_PROTSEQS_REGISTERED with the numeric value of 1714 and hexadecimal representation of 0x6B2 indicates that no protocol sequences have been registered in the system. This error is commonly encountered when attempting to establish a Remote Procedure Call (RPC) connection or when using RPC-based services.
Technical Meaning
The RPC_S_NO_PROTSEQS_REGISTERED error code signifies that the necessary protocol sequences required for an RPC operation are not available or registered in the system. Protocol sequences are essential components of the RPC framework, enabling communication between different applications and services over a network.
Error Details
This error typically occurs when:
- An application attempts to use an RPC service but fails because no protocol sequences have been registered for that service.
- The RPC runtime environment is missing or improperly configured.
- There might be issues with the registration of RPC servers or clients in the system.
Usage Context
This error code can appear in various scenarios, such as:
- When an application tries to make a remote procedure call but fails due to unregistered protocol sequences.
- During initialization of RPC-based services where necessary protocols are not available.
- In environments where network configurations or service registrations are incomplete.
Developer Interpretation
Developers should interpret this error as indicating that the required protocol sequences for an RPC operation are missing. This can be due to a misconfiguration, missing components, or issues with the registration process. Developers should ensure that all necessary protocols and services are properly registered before attempting to use them.
