STATUS_FWP_PROVIDER_NOT_FOUND
The policy owner object cannot be found
STATUS_FWP_PROVIDER_NOT_FOUND means that the WFP provider object named by the operation is absent. A provider is a policy-owner identity used to group and secure WFP objects; it is not the same thing as a provider context, filter, callout, network adapter, or Windows service process.
This often indicates an installation or lifecycle mismatch: the provider was never added, was removed during cleanup, or the caller is using a different GUID than the policy installer. Confirm ownership and access control before recreating objects. Reusing a new provider GUID without understanding existing dependencies can orphan filters, sublayers, or diagnostic associations.
What to verify
- Verify the provider GUID, display name, owner, and installation transaction.
- Check whether related filters and sublayers were installed under the same provider.
- Review access-control and service-start ordering when operations work only under an elevated account.
- Do not confuse a missing provider with a missing cryptographic or network driver.
