We have not had any issues with 2008r2, 2012r2, or 2019 servers and those have all updated normally. So I had to install VMWare tools, configure the nic correctly and reboot them to bring them back online. We just upgraded to 6.7u2 and had about (10)2016 servers go offline last night when they were rebooting for windows updates(and attempting to upgrade tools to 10341)., When I connected to the console on them they had rebooted for windows updates, were complaining that they still needed vmware tools installed, and were missing all of their NICs(vmxnet 3). This has always worked fine as when the servers go to reboot for Windows Updates, they will just reboot again automatically for vmware tools updates during that same maintenance window. So almost 100% of our VMs had version 10287. We were running 6.5u2 and have typically set our Windows VMs to 'Check and Upgrade VMWare Tools before each power on'.
