Evidence to capture for ERROR_NDIS_ADAPTER_REMOVED

Record the exact COM method or Windows API, its input object, the calling thread, and the full 0x80340018 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 ERROR_NDIS_ADAPTER_REMOVED or the ndis / adapter / removed operation.
For ERROR_NDIS_ADAPTER_REMOVED, check the documented return contract of the specific API because the same HRESULT can require different recovery in different interfaces.

Retry and recovery for ERROR_NDIS_ADAPTER_REMOVED

Retry ERROR_NDIS_ADAPTER_REMOVED only when the owning API documents a transient state or after the condition described as “The network interface has been removed.” has changed. For ERROR_NDIS_ADAPTER_REMOVED, configuration, policy, format, and authorization failures normally require correction first; an immediate loop can hide the original call site and add secondary errors.
