Hi,

I have a weird problem that I am trying to solve.

We have a hyper-v host running Windows Server 2012 R2 with 3 VMs. The host has 2 network cards Intel 82574L. The first card is configured as the management card for the host and the second is dedicated to the hyper-v external virtual switch.

What happens is this. As soon as I reboot the host, I get a lot of packet loss (about 50%) on the Host but not the VMs. If I change the static IP address, it works just fine but only until I reboot.

I already changed the cards drivers and also tried disabling IPv6 but no success. I also configured the Host on the second card to see if it was a hardware issue but the problem remained.

Thanks
