STATUS_FWP_PROVIDER_CONTEXT_MISMATCH
A provider context was used with an incompatible WFP object
These status values come from the Windows Filtering Platform path. For STATUS_FWP_PROVIDER_CONTEXT_MISMATCH, wFP classifies traffic through layers, filters, provider contexts, sublayers, and callouts; IPsec policy is also configured through WFP at IKE/AuthIP-related layers.
Provider contexts carry typed data for filters and callouts. This status means the supplied provider context exists but has a type that does not match the object or layer expecting it.
For STATUS_FWP_PROVIDER_CONTEXT_MISMATCH, for diagnostics, keep the failing API call, layer or sublayer key, provider context type, filter condition set, callout id, engine state, and whether the Base Filtering Engine, IKEEXT, TCP/IP stack, or L2 path was ready.
What to inspect
- Record the provider context key and type.
- Check that IPsec, callout, and classification contexts are not interchanged.
- Refresh provider-context enumeration before reusing cached keys.
