On MSDN you can find a new Hyper-V network configuration tool which lets you disable and enable protocol bindings from the command line at the parent partition level. It is great stuff for Server Core en Hyper-V Server administrators.

The tool is written by Paul Despe, program manager from the Microsoft Hyper-V team.

Get the options with nvspbind.exe /?

Disable netbios from the selected adapter

nvspbind -d {0EA93B34-DEE7-4CDF-B232266E3F0B9D72} ms_netbios

Just type nvspbind again to verify the protocol binding

And change it back to enabled again with:

nvspbind -e {0EA93B34-DEE7-4CDF-B232266E3F0B9D72} ms_netbios

John Howard pointed me to another tool called nvspcrub which helps out if you managed to ruin your virtual network configuration :-)
