Hi Ben,
Thank you very much for your info! I am sorry to keep asking 
So...for number 1 put down in my first post.... should I have "Syncronize guest time with host" checked for my domain controller? Let's assume #2 is done.
As for #2, should I sync the VM Host time with a domain controller or internet source? In turn, after #1 and #2 is done, a VM guest which is a Domain Controller will sync the time with the host instead?
I am sorry if I keep repeating my questions...and hope you can help.... thank you very much.
