This says a couple of important things.
The most important is that since IIS is responding (the "Your browser has sent..."),
you know that IIS is answering Port 80. That gives rules out most problems (DNS
problems, routing issues, binding issues with 2 programs trying to grab port 80,
etc.). The IIS service definitely has not stopped, and definitely is at least getting
something.
Microsoft's MSDN doesn't seem to have any information on that error message (???). If
Microsoft is telling the truth, and it really does think that the request is
malformed, there aren't many possibilities. If you have a packet sniffer, you can see
exactly what is sent to the web server. With my IE5, the only thing that the browser
sends (when you first go to a web site) that the server could possibly choke on is the
HOST: HTTP header. If you enter "www.mydomain.com", the browser will send "HOST:
www.mydomain.com".
If IIS doesn't recognize that domain, it may choke. Either that, or IIS isn't working
properly, in my opinion.
Try entering just the IP address (http://12.34.56.78) and see if that works. If it
does, then IIS is choking on the domain in the HOST HTTP header.
