Accessing localhost on IIS7 from another computer on the network

Solution 1:

As @Johnh said it is most likely your firewall.

Open up port 80 on your firewall or whatever port you are hosting the local site on should it be a nonstandard port.

+1 for testing with telnet. Will give you a quick and definit answer on if the Web Server has the proper port open.

Solution 2:

Campo is correct, you most likely need to open a port. Here's how: (on windows 7)

1. Open Control Panel
2. Windows firewall
3. Select advanced settings
4. Select Inbound rules

5. Select "New Inbound Rule"

   Specify local ports 80, 8081. Allow Domain
