Hyper-V Network Card No External Access

Hi,

I have a really weird problem with my Hyper-V VMs. I have a win12k server running hyper-v, 2 VM servers and 2 Win7 Pro workstations. The server has 64gb ram, 2 CPUs with 16 cores each, 4 NICs in a single team - Microsoft Network Adapter Multiplexor Driver - I created a external switch on the Hyper-V infrastructure connecting the NIC team to the Hyper-V switch vEthernet (VM NIC).

The hyper-v and the two server VMs are all on fixed IPs and the Win7 Pro on DHCP. The Hyper-V Server has DNS and DHCP installed. There are two other physical WIN 7 Pro workstations on the network and all 4 Win7 Pro machines get DHCP addresses from the DHCP server.

Now the problem; I have no problems with the two physical win7 pro workstations, the two VMs one can browse the external internet and the other can't. The weird thing is that they both have correct settings under the IP Configuration, which is below; but one seems to be in internal mode only,  as I can see the internal network but nothing external to the network. Any 

Configuration for the VM that is fine

To further complicate things, if I turn off on of the VMs, after a while the other starts working fine. 

So, any help would be appreciated as this is getting frustrating.

thanks
