Virtual PC 2007 SP1 on XP, Win7 guest and no internet

[Force Flow]

I've been fiddling with this for a few days now.

I'm running Virtual PC 2007 SP1 on an XP SP3 host. I have an XP SP3 guest and a Windows 7 SP1 guest (both provided by Microsoft).

The XP SP3 guest has internet access using the Shared Networking (NAT) networking adapter. The Windows 7 guest has no internet access. I've tried both the NAT adapter and the host's actual NIC. For both cases, an IP address gets assigned, but internet access is not available.

I've added the "Virtual Machine Network Service" to the host's network adapter, but that didn't seem to change anything.

Any ideas?

I found this:

Unable to Connect to Internet in Virtual PC with NAT Shared Networking NAT on Windows XP Guest « My Digital Life

Basically, for Vista and Windows 7, the DNS entries need to be set to the gateway of the NAT shared connection: 192.168.131.254

Is that only required when using Win XP SP3 as the host? I use Virtual PC (XP Mode) on Win 7 with XP SP3 guest and haven't needed to add that DNS entry.

Personally, I prefer other virtual software such as VMWare Player and VirtualBox.

I suspect it's only when XP is the host. But...when XP is a guest, it doesn't need the DNS entry at all. The reason for the DNS entry is a security measure in vista/7 to prevent spoofing of DNS responses.

Yes, I prefer virtualbox as well, but Microsoft only offers their free VPC images in the VPC format.

There are ways to get the VPD disk converted over to VDI disk for virtualbox, but I haven't attempted it. A quick search pulled up this:
