It looks more like a registry problem to me otherwise it is hard to explain why would it work after a first boot with uninstalled NIC. All my previous attempts to run a repair install in Windows never produced any positive results if the problem was in registry. I can probably try, usually it does not cause a big trouble, although sometimes it does.

TCPIP.SYS was verified to be identical to the same from a healthy machine.

All services are running with no glitches.

Windows reinstallation is always a cure but not inexpensive.
