cannot connect to server using iPhone wi-fi

Hi,

I have LMS installed on a W7 PC connected to the router using a wired connection. I have a SBT connected to the LMS server using wireless and everything works ok so no issue there.

The problem is I want to use an iPhone and iPeng (eventually) to control the LMS installed on the pc but when I try to connect to the server IP address it doesn't work - I get an error message saying web address cannot be found. The iPhone is connected to the wi-fi from the router as I can browse the internet and it also shows up when I look at the network map in the routers management interface page.

I think that it is an issue with the firewall or the Norton setup. When I go into turn the firewall off it says that it is being controlled - tried turning off the firewall and intrusion bits in Norton but it still didn't work.

I can ping the LMS pc from another W7 one which is connected to the same router but I can't connect to the server ip address using a browser.

Any ideas for the best way to fix this and get it working so I can control it from the iPhone?

Thanks for any help,
