The Server is for the local area network only. There are no proxy servers.
It has more that one web sites. And because 443 is already in use, I have to
use another port.

I logon locally on the HTTPS server's console and connect to
https://server:port/
1. If the address is typed in the address bar of Internet Explorer, I can
navigate to any subfolder - there is no problem with the virtual
directories.
2. If I use Web Folders to view the content as folders, When I double click
on a virtual directory, Internet Explorer will try open
http://server/virtual
instead of
https://server:port/virtual/
That's why it displays an error message.
I think that Microsoft should investigate this problem and fix it as an
update for Windows.

If You have a HTTPS server running IIS 6 in hand You may try to reproduce
the error.
