My Ethernet adapter (I217-V) was working fine before this update. As soon as the update was done, it shows as Unidentified Network. Setting IPv4 to a specific IP address does not seem to help and network still shows as unidentified. Rebooting the Router and/or the computer does not seem to help. Tried updating the drivers, but they show as the latest. This adapter was one which was not being recognized by the earlier Windows 10 builds. The trouble shooter seems to say some network protocol in missing but cannot fix it. My WiFi adapter works fine still. Not sure what else to try.. looks like the DHCP client is running in services... I will try to rollback the update later if no one has any suggestions.
