NAP_E_NOT_INITIALIZED

The NAP entity has not been initialized

NAP_E_NOT_INITIALIZED is HRESULT 0x80270007 (signed decimal -2144927737, unsigned decimal 2150039559). AllStat, using winerror.h, describes it as “The entity is not initialized with the NAP system.” The value has failure severity, facility 0x27, and code field 0x0007.

This is a legacy Network Access Protection result: Microsoft states that NAP is unavailable starting with Windows 10 and that current Windows Server releases do not include the former NAP, HRA, and HCAP roles; use the code for supported legacy systems, archived telemetry, compatibility components, or migrations rather than assuming a modern machine should expose the old platform.

Runtime sequencing failed after registration

This HRESULT describes an object-lifecycle error. Microsoft documents it for SHA binding methods such as GetSystemIsolationInfo when Initialize has not previously succeeded. Registered but unbound SHAs can also cause NapAgent to generate an error SoH containing NAP_E_NOT_INITIALIZED for the corresponding SHV. The code does not mean the health check itself found a noncompliant machine.

Sequencing defects

  • A caller invokes a binding method immediately after COM object creation and skips Initialize.
  • Initialize failed, but later code retained the object and treated it as ready.
  • Uninitialize completed while another thread continued using the old binding instance.
  • A NapAgent disconnect/restart invalidated assumptions in a wrapper that does not respect the documented rebind behavior.
  • Initialization state is stored globally while multiple SHA instances have independent lifetimes.

Lifecycle evidence

  • Log the binding instance identity, Initialize HRESULT, entity ID, callback pointer generation, and every Uninitialize transition.
  • Capture thread IDs and ordering for the first method call after object creation or service restart.
  • Record RPC_E_DISCONNECTED events separately; the interface documents automatic recovery when NapAgent restarts.
  • For a server-observed error SoH, preserve the system-generated flag and health ID to identify the unbound client SHA.

Correcting the call order

  • Verify that registration exists first; Initialize cannot repair NAP_E_NOT_REGISTERED.
  • Call Initialize once with the stable SystemHealthEntityId and a callback object that remains alive until Uninitialize.
  • Publish the binding to worker threads only after Initialize returns success.
  • On shutdown, stop users of the object before Uninitialize and prevent reuse of the retired generation.

Difference from nearby NAP results

NAP_E_NOT_REGISTERED is an installation/management-state problem; NAP_E_NOT_INITIALIZED is a runtime-state problem after registration. NAP_E_SERVICE_NOT_RUNNING means the NapAgent process is unavailable. RPC_E_DISCONNECTED is the documented interface-level signal for an agent stop and can recover automatically after restart.

Retry and recovery

Initialization can be retried after its prerequisite registration and service state are valid. Do not continue with partial outputs from the failed method. Use an explicit state machine—created, initializing, bound, draining, uninitialized—so a stale object cannot silently re-enter the active path.

Practical scenario

A service creates its SHA binding and starts a monitoring thread before Initialize returns. The worker calls GetSystemIsolationInfo and receives NAP_E_NOT_INITIALIZED. Moving worker publication after successful initialization removes the race without changing health policy.
