I tried that as well in the beginning over here on two servers that I am running. It gave me the same thing. What you can try and do as an alternative if it is just locally on your network. Trying calling up the page by the name of the computer and port which th we page is set up at. Or IP address. As an example over here on my main server I usually access it as Server2:80/index.php once I had completed the set up. if you need to set joomla up the first time around and I'm redoing my second server over here it would be Server2:80/installation/index.php. Since I have active directories running on my primary with DNS running and both my primary and secondary servers have static IP's on them. This is another way of accessing them locally on the network. Give it a try and see if this works. Take a look at the computer name of the server if you are not too sure of the name. It will help you out.
