DNS is fine and I can see in the logs that the server is talking to the laptops but changes sit as 'pending' for a couple of hours before successfully pushing to the machines.
In the Service Helper log I have this
[2017/01/30 08:47:50.518] Building missing profile caches failed! (2)
In /Library/Logs/ProfileManager/profilemanager.log I have this
[2017/01/30 08:47:50.320] E: ProfileCacheBuilder: Exception caught Couldn't find DataFile with ID=1:

Any help would be greatly appreciated.

In every case I've personally seen, those type of issues are related to hardware being not supported or overworked.
I would suggest reviewing this guide by Apple where you can clearly see the limitations and expectations of what OSX Server, in today's market, is meant to run. I saw log entries like yours, while trying to run about 300 users in combination with several others "services" on a single Mac mini, and if you read the above carefully, you'll see that the mini's are only spec'd for a single service each (well, basically).
If this doesn't help please comment back with much more specific hardware info, and number of users, etc., and I can update the answer, and we can all gladly further troubleshoot!
