It's not network locations per se, but the network discovery setting under sharing options, the radio button marked "Turn on Network Discovery". I've found a PowerShell command to turn that on in my image, but it does not carry over to the coreload. I've tried running it from a provisioning task, but usually if network discovery is off, then provisioning does not even complete. This was (is) not a problem in Windows 7, but is happening very frequently in Windows 10.
