Right now, you have "localhost" in the URL. That tells the browser to look at the user's computer. Instead, you should be using the name of the machine where the Forms server is installed, e.g. https://yourMachineName.yourDomain.com/Forms/Mileage .

Furthermore, you may need to talk to your IT department about options for making the URL available to these employees that are outside the network. Often, there is a firewall in place that prevents people from accessing internal machines from external places.

Some options you can have your IT department look into include:

• Having these employees "remote in" to your network
• Putting Forms in the "DMZ" (a place outside the internal firewall, but more protected that the general internet)
• A proxy in the DMZ (they can reference this post)
