So, building a simple image reference virtual machine in client hyper-V the task sequence keeps error'ing out because it can not connect to the deployment share to complete the build.
But here is what is strange.
I cancel the task sequence and error out to a command line. From the command line, ipconfig returns a healthy set of connection setting (dns, etc), I can ping google.com, msn.com, etc. and get a response, connect to the network via IE explorer and I can see a host of network shares BUT not the guest OS share.
AND, when I ping the guest OS IP, from the WinPE VM, it times out. Likewise when I ping the VM from the guest OS it times out.
Firewall disabled. MDT 2010u1/ADK.
What am I missing?
