An unusual dns question

Win2k fails to connect using Netscape OR IE, but does connect when using the
https prefix. NS 6.2 responds with "The connection was refused...", whereas
NS 3 responds that there was "no response". IE just times out with "page
cannot be displayed". I can't explain why NS on Win95 connects, although it
seems to me that I remember a setting somewhere that auto-completes the
prefixes on URLs that do not respond or maybe don't have a DNS entry.
