IIS7 Stopped site

I heard that in IIS7 when one of the site is stopped, the request to that site's root is served from the default site.

But when I stop the site, the request is not served from the default site. Is there any setting. I just want to make it behave like that when site (Say 'site1') is st开发者_JAVA技巧opped, IIS should display iisstart.htm page (Which is in the default site).

Why it is not working in my case?

Well a little bit outdated anwser, but maybe someone will find it useful:

Default site's bindings bust be configured properly: IP Address: all unassigned or your special IP Port: 80 Alias: - leave this field empty

now default site will start to process all requests, that were not picked up by other sites.
