Ben Armstrong offers us a new code snippet to help get the network name of the virtual machine through the COM API.  According to Ben, Virtual Server 2005 R2 SP1 has added a few new bells and whistles to the COM API, one of which is the GuestOS.ComputerName property. 

And he says, the great thing about this is that if you want to automate a process that connects to a virtual machine over the network - and be able to handle random network names - then this will allow you to do it.

Option Explicit 

Dim vs, vm, vmName, vmGuestName

vmName = "Windows NT 4.0 CVS Server"

'Connect to Virtual Server 

Set vs = CreateObject("VirtualServer.Application")

'Connect to VM

Set vm = vs.FindVirtualMachine(vmName)

vmGuestName = vm.GuestOS.ComputerName 

WScript.Echo "The virtual machine " & Chr(34) & vmName & Chr(34)

WScript.Echo "Has a guest operating system configured with a network name of " & Chr(34) & vmGuestName & Chr(34)

As usual, thank Ben for this help by going here to the original post.
