1) After upgrading to windows 10 on one computer VMware virtual machine was not starting and an error was displaying “Internal Error” for all VM’s
The issue was due to the VMware authentication service didn’t start for some reason. After changing the startup type to ‘Automatic (delayed start)’ the issue was fixed.
Finally after resetting the virtual network to ‘Restore Default’ it worked !
The above screen can be reached by Edit -> Virtual Network Editor
