WS_E_NOT_SUPPORTED
WS_E_NOT_SUPPORTED is a Windows Web Services API HRESULT. It means that the requested Windows Web Services feature is not supported by the current Windows platform, installed components, or active transport configuration.
What to check for WS_E_NOT_SUPPORTED
- Verify the supported Windows versions, installed API components and deployment architecture.
- Check that the selected binding, security feature and transport are supported in this environment.
- Use a documented compatible feature path rather than assuming every platform supports the same capability.
Diagnostic interpretation
This result has the HRESULT value 0x803D0017. AllStat records the condition as “The requested feature is not available on this platform.”.
Evidence to capture
- Capture any IErrorInfo text, activity identifier, event-log entry, and subsystem trace that mentions this result or the ws / supported operation.
- compare the failing machine with a working one at the same configuration boundary: component version, policy, registration, identity, and target resource.
Retry and recovery
Do not retry an unchanged request after WS_E_NOT_SUPPORTED. Change the confirmed precondition first, then rerun the original path and record the next result and final object state.
