HNS_INVALID_POLICY
HNS_INVALID_POLICY is an HRESULT used by Windows Host Networking Service (HNS). It indicates that the policy has missing fields, invalid values, or a combination unsupported by its target.
What to check for HNS_INVALID_POLICY
- Validate the policy schema and required fields for the intended network, endpoint, or port.
- Check that referenced IP addresses, ports, protocols, and endpoint identifiers are valid.
- Apply policies one at a time when isolating an incompatible or malformed rule.

Diagnostic interpretation of HNS_INVALID_POLICY
HNS_INVALID_POLICY has the HRESULT value 0xC03B000D. AllStat records the condition as “The provided policy configuration is invalid or missing parameters.”. For HNS_INVALID_POLICY, 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_INVALID_POLICY
- Record the exact COM method or Windows API, its input object, the calling thread, and the full 0xC03B000D 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_INVALID_POLICY or the hns / policy operation.
- For HNS_INVALID_POLICY, 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_INVALID_POLICY
Retry HNS_INVALID_POLICY only when the owning API documents a transient state or after the condition described as “The provided policy configuration is invalid or missing parameters.” has changed. For HNS_INVALID_POLICY, configuration, policy, format, and authorization failures normally require correction first; an immediate loop can hide the original call site and add secondary errors.
