I've got a Windows 7 Ultimate box. I've downloaded and installed the Windows Virtual PC, and I want to get the Windows XP VM to join our Active Directory (Windows 2003 R2 Server). But I'm running into problems, in that the IP address of my Windows 7 machine, and the VM aren't anywhere near being the same; so as I understand it they're not even on the same network. How do I resolve this issue?
