UWF & Registry Key Exclusions for Networking

I was not totally sure which forum would be best for this question.

I am setting up Windows 8.1 Industry for Kiosk type products. When I enabled UWF with the following exclusions.

HKLM\LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip
HKLM\LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Nsi

I randomly get 169.254.. for the IP address. This happens with both IPv4 DHCP enabled and IPv4 static address assignment.
ipconfig /renew and ipconfig /release report "No operation can be performed on Ethernet while it has its media disconnected."

The link light is on and I see network traffic.
From the network adapter page I can disable/enable the adapter and most of the time it will get a valid IP address.

Thank you

Alan
