Sets MaxNegativeCacheTtl = 0 under Dnscache\Parameters. By default Windows remembers a failed DNS lookup for ~5 minutes (negative caching), so a site/server that JUST came online keeps appearing dead until the cache expires. Setting 0 means failed lookups aren't cached — the next attempt re-queries immediately. Handy for flaky connections, just-provisioned domains, and dev work. Reversible.
MaxTweaks applies this tweak with one click and snapshots your original setting first, so you can revert it cleanly at any time. A System Restore point is offered before batch changes, and every tweak links to its official source.
