Jay05555,   The updates you show don't look correct.  The 2019 Broadcom driver is 21.40.17.70 The 2019 Broadcom Firmware is 21.4.1 Try running those and see if the issue clears up.  Let me know what you see.
Hello all,  So I am running a Dell Poweredge R430 in it I added a NIC: BRCM 10Gb BASET 2P 57406 Adptr with two slots. First I had an installation of hyper-v server 2016 which recognized both slots of this NIC without any problems. I decided to upgrade to Windows Server 2019 and since that moment 1 of the slots is up and the other doesn't show a MAC adress anymore:       I've tried to upgrade the drivers and firmware to the following versions.   And in the ILO it says strangely enough that the OS status is operational:   (on the old firmware/drivers it was not operational)   TLDR: New NIC, 1 port is working, the other is not. According to the DCA administrator both lights are blinking so it should be ok.   Anybody any ideas what else I can do or what can be wrong?   Thanks in advance
Windows server 2019 not recognizing 1 NIC port
