[Zope] Zope on local Win2K machine and IE

Hi! I installed Zope on a local (Win2K) machine that uses a modem dial-up to connect to the internet. Whenever I type in "localhost" or "127.0.0.1" in IE (6) to get to the Zope Server, Windows always prompts me for an internet connection. When I "stay offline", the page does not display. When dialling in, everything works fine. So with IE on Windows 2000, I have to be online to connect to the local (_really_ local, not even LAN) server. I find this stupid and unacceptable. Is there any easy way to get around this problem? Thank you very much in advance for your help, Danny P.S.: Netscape doesn't invoke this prompt, it connects just fine to the local server, straight away.
