RPC_S_UNKNOWN_AUTHZ_SERVICE - 1750 (0x6D6)

Introduction

This document provides a detailed interpretation of the RPC_S_UNKNOWN_AUTHZ_SERVICE error code, which is returned by the Remote Procedure Call (RPC) service when an unknown authorization service is encountered.

Technical Meaning

The RPC_S_UNKNOWN_AUTHZ_SERVICE error code indicates that the RPC runtime attempted to communicate with an authorization service but could not identify or locate it. This typically occurs in scenarios where the RPC client or server expects a specific authorization mechanism, such as Kerberos or NTLM, but the required service is either missing or misconfigured.

Error Details

The numeric value of this error code is 1750, and its hexadecimal representation is 0x6D6. This error suggests that there might be an issue with the configuration or availability of the authorization service expected by the RPC system.

Usage Context

This error can occur in various contexts, such as when making remote procedure calls over a network. The specific context will depend on the application and its interaction with the RPC framework. Common scenarios include:

• Authentication failures during RPC-based operations.
• Configuration issues where the expected authorization service is not present or correctly configured.

Developer Interpretation

Developers should interpret this error as an indication that the RPC runtime could not find a required authorization service. This might be due to several factors, such as missing components, incorrect configuration settings, or network connectivity issues. Developers are advised to review the application's configuration and ensure that all necessary services are available and correctly configured.
