Local development with VirtualBox and Internet Explorer browsers

Has anyone had any issues while setting up their local development system with Mamp Pr开发者_运维知识库o 1.8.4, VirtualBox 3.2.8. For viewing websites in IE browsers. I have three websites that I'm looking at all three work in Firefox, Chrome, Safari. For this example lets just say I have:

dev.site1.com dev.site2.com dev.site3.com

Now site1 works in IE on VirtualBox well, however Site2 and Site3 display a HTTP 500 Internal Server Error on IE 7, IE 8.

The host file has the following:

192.168.56.1 dev.site1.com dev.site2.com dev.site3.com

I'm using a Bridged Network Adapter for the guest operating system.

Has anyone experienced this before?

I've just had weird experiences with the Windows hosts file compared to Linux and would suggest just expanding the hosts file to the following:

192.168.56.1 dev.site1.com
192.168.56.1 dev.site2.com 
192.168.56.1 dev.site3.com
