familiar with Hyper-V, and it addresses issues that affect the configuration of
DXE-820T network adapters and teamed network adapters when Hyper-V is used.
For more information on Hyper-V, see

Single Network Adapter
Windows Server 2008
When configuring a DXE-820T network adapter on a Hyper-V system, be aware of the
following:
An adapter that is to be bound to a virtual network should not be configured for
VLAN tagging through the driver's advanced properties. Instead, Hyper-V should
manage VLAN tagging exclusively.
