I playing in a nested lab and finding that my Win10 instant clones lose their NICs after deploying and user logon.
2nd child comes up with this error status , then all of the VMs lose their NICs as users logon.
Not seen this before and I've done about 8 of these labs before in v7.7... but with Distributed vSwitch !
The VM NIC disappears when not attached to a DVS portgroup. If you configure the Instant clone pool for dedicated assignments,
you need a DVS. Floating assignments will work with standard vswitches but dedicated will not. go figure.
The error message could be expressed better. Gives me the impression the NIC wasn't created.
