How do I access from other computers on the same network?

I've got sitefinity up and running on a Windows 7 machine in our office. I can access it at localhost:10759, or 127.0.0.1:10759 while I'm on that machine. I need to be able to access it form other workstations on our local network, but if I plug in the machine's IP address with the port (http://192.168.1.75:10759), it'll just timeout. I can access the main IIS7 page if I disregard the port. I tried opening the port in windows firewall, but it doesn't seem to have an effect, I'm not able to connect.  Also, the port number keeps changing regularly, so I'd need to keep changing that port number. I don't have any other sites on the server. Can I make it so sitefinity loads on port 80? 

Thanks for any and all help. 

Hello Sam,

In order to access the project from another machine on the same network you need to set-up the project on IIS:
- Configure the IIS to host Sitefinity projects
- http://docs.sitefinity.com/run-projects-on-iis-7-0-and-above

Than access it by: http://<machine name>:<port number> 
for example:
- http://adams (in case on port 80) or
- http://adams:5555 (in case binding on port 5555)

I hope the information helps.

Regards,
