Invalid Backing on a Virtual Machine’s Network adapter.
Have you ever noticed Invalid backing on your Network Adapter in the Virtual Machine Property screen?
Of course not! You are an administrator! …But if you want to see it or are curious what a consultant with limited rights might see, take a look!
Basically, if you see Invalid Backing on your VM and everything (network-wise) is working fine, it’s a permissions issue. You just don’t have the rights to see the networks configured on the host. Nothing much to worry about technically. Politically speaking though, you might want to rethink your strategies…
