Domain network connection is detected as Public

Hi,

I disabled in hyper-v virtual switch option "Allow management operating system to share this connection" to have dedicated psychical network adapter for my virtual guest  - domain controller 2012 r2. But after that, on domain my network connection is treated as "Public" not Domain. I tried to change this using command:

"Set-NetconnectionProfile -InterfaceAlias Ethernet -NetworkCategory Domain"

but I get error: Unable to set NetworkCategory to 'DomainAuthenticated'.  This NetworkCategory type will be set automatically when authenticated to a domain network.

I asked in hyper-v forum already but did not get any help. Please help.
