Networking issue on Ubuntu 10.04 Desktop and 2008 R2 Hyper-V

I have configured a Virtual Ubuntu 10.04 Desktop machine on my 2008 R2 Server and have followed various resources to correctly configure networking but for some reason I am unable to get it working.

Some of the resources i have followed:

That's just  to mention 2 sites.
I have configured static IP and left it DHCP; I have configured my NIC Legacy and as normal; either way I am unable to get any kind of network activity to or from this virtual machine.

Any assistance would be great.

still having a problem with this, did everything mentioned, the drivers are running but still no luck. What i find a bit strange is that the guest os does get a dhcp assigned ip but as soon as the gui loads it loses connectivity...

Any ideas on this?

Ok, so have tried 10.04 Server, 10.10 Desktop and server with no luck. As a test i installed 8.04 Server and it worked straight after installation... weird.
I have installed two 10.10 servers okay with legacy NIC and then synthetic NIC. My synthetic NIC is eth1, not seth0 as stated in the blog post. Try that.

I tried using eth0 and eth1 but that didn't work; think it would work if I use seth0/1
Not sure how to configure synthetic NIC so have just been using legacy.

As I said, it's working for me with 10.10 as eth1. I followed the same blog post you did, and you can see my reply to it that the NIC appeared as eth1 after I edited /etc/network/interfaces and added the eth1 entry and rebooted. A seth0 entry didn't do anything.

Did you run
$sudo update-initramfs - u

and check to see if the drivers are running?
$ lsmod | grep hv_
