Can you get it to work locally? When you run the Web Publishing Tool for the VI, after clicking the Save to Disk button, you're given the option to Connect. This will start your browser. If you can connect this way but not from a different computer, then I would look into your network settings. Maybe you're behind a firewall and the port is not enabled. If you can't connect locally, then maybe the LabVIEW web server is not correctly configured. If you could provide a little more information about your problem, it might help the diagnosis. When you say it doesn't work, does that mean you can't get control or can't see the panel or what? What OS are you on and what browser?
