I have IIS running on a windows 7 ultimate machine (development workstation). I can access the website locally with no issues, but when I try to access the site from the iPhone it just gives one of two errors:

Cannot Open Page
Safari cannot open the page because the server stopped responding


Cannot Open Page
Safari cannot open the page because the server cannot be found

Can't quite figure out what triggers one message vs the other, but both machines (computer and iphone) are on the same wireless network and have the same subnet mask. On the laptop, the network connection is defined as a "home network" and I've turned on all the sharing options I could find.

What other troubleshooting steps can I try?

additional info:

  • just wanted to include that I know that iphones don't support netbios so as such wouldn't be able to resolve the machine name. I am trying to access the machine by IP ...
  • I installed a ping app on the iphone and I'm able to ping the workstation with 0% packet loss

solution was enabling the built-in firewall rule for http traffice on home/work networks :-)

IIS or netbios can't be the issue. Your iphone is just unable to connect. Check your IIS port, make sure that your comp. firewall allows access, and don't forget to type that at the end of ip when trying to access from iphone. e.g. of course you dont' need to do that if it's port 80. good luck

it was definitely on the LAN :-) this was in my home and I wouldn't want outside traffic coming into my laptop's IIS server :-P – Joel Martinez Oct 9 '09 at 17:51

You have to find out the ip of your personal web server (iis). Normally it is in DHCP mode. Type that ip (i.e.
