Can you imagine what would happen if every time anyone ever looked up any hostname they sent out a DNS query?That's what most Unix/Linux/*BSD boxes do unless they are running a local caching name service of some time (BIND, nscd, etc.). I wasn't actually aware that Windows had a DNS cache service.
Open a web browser, go to "foo.bar.com" for some hostname you own. Change the record on the authoritative server and clear the cache on the recursive NS. Reload the page. See if the browser goes to the new IP.
Most desktop OSes do not re-query for the name again.Sometimes this is a browser issue. Sometimes it is an OS issue. Depends on too many variables to which, or both, is at fault in general.
