I was at a customer’s site this week when I ran into an issue with Vista on my laptop.  It kept displaying a network as Unidentified and I could not change this.  This was the loopback adapter that I was using for Virtual Server 2005.  I had recently enabled this adapter so I could move files from my physical laptop to virtual machines.

It turns out the workaround for this is to add a default gateway to the NIC.  That will give you the option to change the label/name for the network connection.  I found the solution for this in the following forum:
