Testing an IIS Express app from an IE 8 VM on my Macbook

by adamstephensen

I am running Windows 8 and Visual Studio on my Mac using Parallels.

The project I am currently working on is configured to use IIS Express, but I want to test it using a VM that contains IE8.

As it turns out this was quite simple to setup.

1. Download the VM from  or

2. Open the VM using Parallels (File, New, Add Existing Virtual Machine).

3. Change the Windows 8 VM and the VM containing IE8 to both obtain their own IP addresses from the local WiFi router.

            Virtual Machine | Configure | Hardware | Network. Change type to WiFi

4. Change the configuration of the web application to use the Windows 8 VMs IP Address

             e.g. change it from http://localhost:63527/  to

5. Edit the binding in your IIS host config file

(You can find it in  %userprofile%\Documents\IISExpress\config\applicationhost.config )

Find the entry for your application and change it from from

<binding protocol=”http” bindingInformation=”*:63527:localhost” />


<binding protocol=”http” bindingInformation=”*:63527:″ />

6. Disable windows firewall on the Windows 8 machine.

7. Run Visual Studio as Administrator and run the application. It will now be accessible from the IE8 Virtual Machine.
