FWP_E_PROVIDER_CONTEXT_MISMATCH

FWP_E_PROVIDER_CONTEXT_MISMATCH means the code supplied a provider context whose declared type does not match what the operation expects.

What to verify for FWP_E_PROVIDER_CONTEXT_MISMATCH

  • Confirm that the provider context was created with the intended WFP context type.
  • Keep the context identifier, callout identifier, and filter reference together in one validated policy object.
  • Do not infer context compatibility from a provider GUID alone; the context type matters.

Diagnostic interpretation

This result has the HRESULT value 0x80320034. AllStat records the condition as “The provider context is of the wrong type.”.

Evidence to capture

  • Capture any IErrorInfo text, activity identifier, event-log entry, and subsystem trace that mentions this result or the fwp / provider / context / mismatch operation.
  • Preserve the first failure in the call chain; a later HRESULT can describe cleanup rather than the original fwp / provider / context / mismatch condition.
