If you have a multi seat environment. I think the best you do is to install the web interface on your first computer (TV-engine) In that case you have to choose localhost in the database tab of the web interface configuration (page 6 of the manual) Note that on this tab is a database login test button. What happens when you hit that button?
Any other computer can be used to access the web interface via your LAN or WAN. then you have to fill in the ip address (or hostname) of your first computer in the browser like this:
http://192.1.1.33:8080. Note that you have to grant the web interface to be accessed through your firewalls. if you want to access the web interface from outside your house, the ip-address is translated by your adsl-modem in the NAT table.
