Server 2012R2 Hyperv slow response and slow pings
We have noticed that in certain environments ping times (latency) is very high to a guest Hyperv host on a physical Server 2012R2 box.
To fix this locate the physical NIC on the host OS that is being used for the Hyperv.
- Go into the NIC properties
- select VMQ VLAN Filtering and set it to Disable as seen below
