I've installed Windows 2003 x64 R2 SP2 under Hyper-V (the Windows Pro 8 edition).

I have a NIC configured but I can't move any traffic on it. In particular I can't send or receive Pings.

Scoreboard

There is a second VM running Ubuntu under the Windows 8 host which is able to send and receive pings from the host O/S .

When I try to ping from Windows 2003 guest to Windows 8 host I get 'Request Timed Out'.

When I try to ping from Windows 8 host to Windows 2003 guest I get 'Reply from 192.168.10.107 Destination Host Unreachable'.

There's no problem pinging from the Ubuntu guest to the Windows 8 host and no problem pinging from the Windows 8 host to the Unbuntu guest.

Environment

Integration services are installed on Windows 2003.

The windows 2003 needs a static IP address of 192.168.10.15.

The Windows 2003 ipconfig output looks like this :

While the host o/s ipconfig output looks like this :

Event Logs

The only things I can see in the event logs which is (a) looks signifcant and (b) is not related to the lack of networking is this :

I'm not sure if that's significant or not.

Hyper-V and NICs

When the Windows 2003 guest was first booted it had no NIC; I subsequently added a 'Legacy Network Connector' which I couldn't get Windows 2003 to recognise; I subsequently removed that and added a 'Standard Network Connector' and at least on the surface this works ... only it doesn't.

'Virtual Network Type' is external.

Although I've only mentioned ping there's no other evidence of network activity.

'Allow incoming echo request' is enabled on the Windows 2003 guest.

HELP ?

What else should I look at or do to resolve this problem ?

EDIT 1: I should have said that I turned off the firewall on the W2003 server for a while and retested the pings; same result.
