HNS_POLICY_NOT_FOUND
HNS_POLICY_NOT_FOUND is an HRESULT used by Windows Host Networking Service (HNS). It indicates that the expected HNS policy is absent from the target network, endpoint, or port.
What to check for HNS_POLICY_NOT_FOUND
- Inspect the object currently targeted by the request and list its configured policies.
- Check whether a previous cleanup or replacement operation removed the policy.
- Apply the policy to the correct object only after the object has been created successfully.

Diagnostic interpretation of HNS_POLICY_NOT_FOUND
HNS_POLICY_NOT_FOUND has the HRESULT value 0xC03B0008. AllStat records the condition as “An expected policy was not found.”. For HNS_POLICY_NOT_FOUND, in practice, interpret that wording at the boundary owned by the Windows component or COM interface that returned the HRESULT, rather than treating the value as a generic Windows message.
Evidence to capture for HNS_POLICY_NOT_FOUND
- Record the exact COM method or Windows API, its input object, the calling thread, and the full 0xC03B0008 value before a wrapper converts it to an exception or Boolean result.
- Capture any IErrorInfo text, activity identifier, event-log entry, and subsystem trace that mentions HNS_POLICY_NOT_FOUND or the hns / policy / found operation.
- For HNS_POLICY_NOT_FOUND, compare the failing machine with a working one at the same configuration boundary: component version, policy, registration, identity, and target resource.
Retry and recovery for HNS_POLICY_NOT_FOUND
Retry HNS_POLICY_NOT_FOUND only when the owning API documents a transient state or after the condition described as “An expected policy was not found.” has changed. For HNS_POLICY_NOT_FOUND, configuration, policy, format, and authorization failures normally require correction first; an immediate loop can hide the original call site and add secondary errors.
