I've enabled the Hyper-V role on a Windows 2008 Server Standard R2 box.
From there, I created a new VM named XXX-VIRT1. Have joined this virtual machine to our domain and have successfully reached it via Remote Desktop from an offsite location. Everything works as it should.
I must create 10 of these VM's; so, I decided to use the "Export / Import" method and followed a couple of TechNet documents to do so. After using this process to create XXX-VIRT2, I had to change Computer Name, Static IP address, UserName, etc. to satisfy authentication of my Domain Controller. Connecting to XXX-VIRT2 via Remote Desktop also worked.
However, now that XXX-VIRT2 has been successfully created and tested, when I started up XXX-VIRT1, I found that my connection to the Internet has been lost on this machine. Also, connectivity to XXX-VIRT1 via Remote Desktop no longer works.
When browsing to the location of the .vhd file on the server box, I expected to see 2 files there: XXX-VIRT1 and XXX-VIRT2. However, nothing is there except New Virtual machine.vhd.
