With the NCU and NIC drivers, if you update the NCU but don't update the drivers at the same time you will probably have issues. I don't know why HP does this, but the latest version of the NCU sometimes has trouble "seeing" the NICs if they're using an older version, even just one version old.
I learned to try and update my NIC drivers and NCU at the same time. You might lose your network connection sometimes (like you could lose your teaming setup until everything is installed) so I usually copy the install files locally and use an ILO remote session to do the install.
The problem didn't seem as bad with newer NICs, and under Windows Server 2012 there is no more NCU anyway (you use the built in load-balancing/fail-over NIC feature).
