. . . for clarity, I notice that there are a number of VMnet interfaces shown within the Virtual Network Editor (subnet addresses obscured), therefore:

- Are the 'Win 10', 'Win 2016' and 'Win 2019' server VMs set to NAT [VMnet8], if so compare the allocated IPs and subnet against the ones allocated to the Linux VMs.

- could you confirm that virtual network interface for each of the Linux VMs are set to NAT [VMnet8] and have default settings (LAN segment, Advanced), again compare with the WIn settings.

- when pinging between the Linux, Windows Host and VMs, is that by name or IP ?

- Are all of the IPs unique between each of the VMs.
