RPC_NT_INVALID_ASYNC_HANDLE

Invalid asynchronous RPC handle

RPC_NT_INVALID_ASYNC_HANDLE belongs to the Windows RPC runtime NTSTATUS facility. For RPC_NT_INVALID_ASYNC_HANDLE, mS-RPCE extends the DCE/RPC model: generated stubs marshal parameters, the runtime binds to an endpoint and protocol sequence, and security or transport failures can be returned as RPC facility status values.

Asynchronous RPC uses an RPC_ASYNC_STATE handle to track call progress, notification, cancellation, and completion. This status means the handle passed to the runtime is not valid for the operation.

Typical causes are skipping RpcAsyncInitializeHandle, reusing a completed handle without reinitialization, stack lifetime bugs, or passing a handle that belongs to a different call.

What to check for RPC_NT_INVALID_ASYNC_HANDLE

Verify that the async state was initialized with the expected structure size.
Ensure the handle remains alive until completion or cancellation is fully processed.
Do not reuse the same async state concurrently for multiple outstanding calls.
