Hyper-V Senior Developer Keith Mange has released his NVSPBIND tool for free-as-in-beer. Watch the 10 minute video demo at: http://www.microsoft.com/showcase/en/us/details/d815cd2b-3c03-4c41-bdc8-c2794850b4ed or click the image.
NVSPBIND is a tool for modifying network bindings from the command line. It is especially useful in Server Core environments with the Hyper-V role enabled. Keith also published nvspcrub.js, a tool for removing Hyper-V Virtual Networking Configuration from the parent partition. It is especially useful in Server Core environments when the Hyper-V UI may not be available. Available at: http://code.msdn.microsoft.com/nvspscrub
