Hello, Did you move to VMware in the end or are you still on HyperV?   If HyperV, make sure you are not using a Gen2 machine. Gen2 do not have Floppy Drives so the Instant prov will not work.   If you're on VMware, make sure a Floppy Device is present in the Parent VM.  Thanks, Andrew.
I have followed the Administration Guide regarding the instant provisioning and I have made sure all the necessary steps has been implemented, except the MKS server configuration which is I'm fine with it for my testing, but I can't seems the Desktops which are provisioned are having the names which I've specified nor they are sysprepred. Any help?
