Add localhost.localdomain to local DNS (or hosts file)

1. Goto Start > Run
2. Type in "system32" (without the quotations)
3. Goto the folder called "drivers"
4. Goto the folder called "etc"

The hosts file should be in there. Just open it up with notepad or something and add in 127.0.0.1 localhost.localdomain
