Solution:
Error 85440 is almost always resolvable by systematically isolating the issue between the client licensing service (checked via the link: diagnostic), network connectivity, and the server-side NLM. The link: parameter is a critical first-step diagnostic that prevents administrators from wasting time on the wrong component.
