Why are my Clients so inconsistent?

[jfdensmore]

Goal: Push out 1709 upgrade to any computer that is 1703  via a Task Sequence.

Problem #1.   

I have a collection that looks for os build 15063. It finds 109 computers.  out of these computers 30 of them are actually running 1709 not 1703.  WTH?  

What process pushes this information from the client?   Is it the machine policy?

Is there a better way to build this collection? 

Problem #2

When i deploy the image to this collection, some of the computers are getting it and some are not.  (These are All running 1703)  I force machine policy, and refresh but no go. I have reinstalled the client, Verified machines are in the same boundary. 

What logs would i look at to determine the issue here??

 

As always thank you in advance for taking the time to look at this and help!!

Without knowing how to created the collection, no one can answer this question without guessing. 

Heartbeat or hardware is the best anwsers.
