Although the examples below show the LAN Zone and HTTPS (Port 443) they can apply to any Zone and any Port that is required. Usually this is done intentionally as a "tarpit", which is where a system will provide positive feedback on just about every port, causes nmap to be useless (since you don't get an accurate scan of what's open or not) and makes actually probing anything take a really long time, since you don't know if you're connected to the tarpit or an actual service.
