This tutorial is based on the presumption that you have successfully installed MAMP on your Mac and are running multiple vhosts. If you have not done this yet, please see this link.
What I’m Working With
- 15″ MacBook Pro
- OS X 10.5.7
- MAMP 1.4.1 (Default MAMP Port Settings)
- Parallels 4.0.3844
- Windows XP SP3
Step 1: Go into the Mac’s System Preferences. Choose Network, and select Parallels Host-Only Network. Copy the IP address here as you will use it for the Windows XP Hosts file. 
Step 2: Locate and open (with Notepad or another text editor of your choice) your Hosts file for Windows XP. It should be in C:\WINDOWS\system32\drivers\etc. Add the aliases and Host-Only IP you copied address like so (I used the same aliases that I used on my Mac): 
Step 3: Change the Parallels network setting to Host-Only Networking. 
Finishing: Ok, everything is configured. Use the alias for the site you want to view in Internet Explorer: http://mysweetsite.local:8888/ and hit enter ;)
