You also need to see what port did you assign to that site and if that port is opened for in/out - going traffic in your Windows Firewall. Would not hurt to verify is there is any other applications using same port for any reason.
Application pool need to be verified as well.
When you done you need to put either DNS entry for your site or add your site to host file on machines from where you desire to have access to your site.
Easier way would be just access site using IP but in any case Firewall is a place to start.
