Could you be a little more specific?
I sounds like you are having trouble with the "network location" setting in Windows- where you tell the OS the network that is connected is work, public or home.
If this is the case, it's pretty easy to set in the unattend.xml using Windows System Image manager from the Windows ADK.
For windows 10, you should set this in the specialize pass with the unattend.xml having text as below:
<component name="Microsoft-Windows-Shell-Setup" processorArchitecture="amd64" publicKeyToken="31bf3856ad364e35" language="neutral" versionScope="nonSxS" xmlns:wcm="http://schemas.microsoft.com/WMIConfig/2002/State" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
