That seems to be working a bit better than last time, I think the
network never even connected.

Can you try disabling all offloads in Windows (checksum and large send)?

Also try running wireshark or another traffic capture routine and see
what that picks up. It could be getting corrupt packets or no packets at

There could maybe be something wrong with broadcast packets... try
adding an arp entry manually in Dom0 for DomU and then try pinging it.
