Server 2012 R2, Hyper-V VM-PDC w/AD DS, DNS

I originally had an Event ID 12 and successfully setup the time service as covered in this post. The Event ID 12 no longer shows up during startups. However, I am now seeing Event ID 144 which repeats from time to time saying

The time service has stopped advertising as a good time source

So does the time service re-advertise as good, or is it 'gone until fixed' once ID 144 shows up?

Hence my question, how do I check if the time service is advertising again?

Also, what causes it to stop advertising? Is it just an inability to sync externally every now and then? If I have to do something to fix this, where do I start?

nltest /dsgetdc:domain.com /server:dcname

Will have the TIMESERV flag if it is advertising.

You probably need to run: 

w32tm /query /status /verbose /computer:dcname

To get more information about the problem. Potential causes include it may be synchronizing from the hardware/cmos clock, or using the time synchronization of the Hyper-V integration services.
