I finally figured out how to get internet access on a Windows 7 guest running on Virtual PC 2007, as described here. But one I don't get. I am not able to ping or tracert anything. Google.com for example. On the host I can both ping and tracert it. On the guest I can do it to neither of them. All I get is Request timed out. But I can visit google.com in IE.
What is going on?
