I upgraded our Win7 system to Win10, in the device manager I get the following message: driver not installed and not known.
PCI Serial Port, PCI bus 0, device 22, function 3
PCI Serial Port, PCI slot 1, PCI bus 7, device 0, function 0
SAS Controller, PCI bus 2, device 0, function 0
any suggestions would be much appreciated.

if you are not on a domain and using the Intel remote control server/software disable the Intel "AMT" option in the bios under the security section and remove the intel AMT software as it has known security issues this will resolve your com 3 no driver issue
if you are on a domain and use this software install the Intel Management Engine Software 22.214.171.1248 Rev.B
from the HP z420 download page
the z420 does not come with a SAS controller on the base systems (it is a optional add in card) please confirm you have a add in SAS/SATA card and the make/model

thanks for your reply.
We did use the Intel remote control server/software in the past (not now). I will install the new version 11.0.01158 Rev.B as you suggested when we use/need remote control again.
I checked the SAS controller - nothing added here; so maybe this is an issue related to the upgrade to Win10?

you may need the intel RSTe (enterprise) driver installed the latest that works on the z420 chipset is the 126.96.36.1991
if you provide the Hardware Id of the device we can then Id just what device is missing the driver

is the onboard Intel SATA for the c600 series chipset please install the correct RSTe driver v 4.5.xxxx i linked to previously
are for the Intel "AMT" com port, again, please either disable the intel AMT in the bios or install the win 10 compatible Intel AMT package i referenced previously
either way, uninstall the current AMT package (if the win 10 upgrade did not do this)
