STATUS_FWP_IN_USE
Delete order conflicts with the WFP reference graph
STATUS_FWP_IN_USE means that the target object still has dependents. In WFP, a filter can reference a provider, sublayer, callout, and provider context; those relationships make an apparently unused management object part of active policy.
The appropriate action is to inventory the dependents and remove or relink them deliberately. Deleting a provider, callout, or sublayer first is not a safe substitute for identifying filters that reference it, because the dependent rules determine the actual enforcement behavior.
Useful evidence
- The target object type, GUID or run-time ID, and owning provider.
- Filters and contexts that reference the object, including their layers and actions.
- Whether the object is persistent, static, or dynamic and whether the intended deletion belongs to the same session.
- The planned reverse order of removal, recorded before modifying policy.
