RPC_S_NO_ENDPOINT_FOUND - 1708 (0x6AC)
No endpoint was found.
Updated: Feb 21, 2026
Technical Background
The RPC_S_NO_ENDPOINT_FOUND error, with the numeric value 1708 (0x6AC), is a specific error code in the Windows API that indicates an issue related to Remote Procedure Call (RPC) endpoint resolution. This error typically arises when the system cannot find an appropriate endpoint for the requested operation.
Error Details
Technical Meaning
The RPC_S_NO_ENDPOINT_FOUND error signifies that the RPC runtime was unable to locate a suitable endpoint for the service or resource being accessed. An endpoint in this context refers to a specific configuration entry within the RPC runtime, which defines how and where a particular service can be reached.
Common Causes
- Incorrect Service Name: The service name specified might not match any registered endpoints.
- Endpoint Configuration Issues: Incorrect or missing configuration of the RPC endpoint mapper (EPM) service.
- Network Connectivity Problems: Network issues that prevent the system from resolving the required endpoint.
- Service Not Registered: The service in question is not properly registered with the RPC runtime.
Real-World Context
This error can occur when attempting to access a remote service via RPC, such as when using DCOM (Distributed Component Object Model) or other RPC-based services. It often manifests during application startup or when performing operations that require network communication.
Is This Error Critical?
The criticality of this error depends on the context in which it occurs. If the operation is non-critical, such as a background task, the impact might be minimal. However, if the operation is part of a mission-critical application or service, the error could lead to significant issues.
How to Diagnose
Reviewing Operation Context
- Verify that the correct service name and parameters are being used.
- Check network connectivity and ensure that the required endpoints are reachable.
Validating Parameters
- Ensure that all input parameters, including service names and endpoint configurations, are correctly specified.
Confirming Object Types
- Validate that the object types involved in the operation match the expected types for the RPC service.
Verifying Input Data
- Check for any corrupted or invalid data that might affect endpoint resolution.
How to Resolve
Correct Parameter Usage
- Double-check the parameters passed to the RPC function, ensuring they are correct and complete.
Adjust Operation Context
- Ensure that all network-related configurations are correctly set up, including firewall rules and network settings.
Restore Data
- If data corruption is suspected, restore or reconfigure any necessary endpoint mappings.
Retry Operation with Valid Inputs
- Attempt to perform the operation again with valid inputs. If the issue persists, consider restarting the EPM service or related services.
Developer Notes
When developing applications that rely on RPC, ensure robust error handling and validation of all input parameters. Regularly check for updates and patches related to network configurations and RPC runtime components to avoid such issues.
