Earlier this week, John Howard alerted the world of the availability of “NVSPBind”. This is a handy command line tool that allows you to edit the network protocol bindings on a virtual network adapter (note, it does not work if you are not using virtual networks). This is very useful if you are running Hyper-V Server or Hyper-V on a Windows Server core installation.
Though I would like to spend a moment singing the praises of an older tool, NVSPScrub (available here: http://code.msdn.microsoft.com/nvspscrub).
This tool provides for a quick and easy way to delete all virtual network settings on a system. This can be a real life saver if you have been playing around the the Hyper-V WMI interfaces and have messed up the network configuration on your server.
It has saved me from myself a number of times now.
