NetBoot issues using 10.12.x nbi

[a_simmons]

Since updating the nbi to 10.12.x I have been unable to NetBoot from different subsets. I'm also only able to NetBoot to up to around 7 devices at a time to Macs on the same subnet.
If I restore the 10.11 NBI it works fine.
I've tried multiple images using autodmg and creating a minimal base image. I've also tried tweaking the settings in autocaspernbi, but I keep getting the same result.
Is anyone else having similar issues with netbooting across subjects with 10.12.x?

I just created mine last week with 10.12.2 and it works fine with different subnets. When i have strange issues like that a reboot of our OSX server normally fixes it.

Thanks William, I'll test it again with 10.12.3 and see how it goes.

What version of the netsus appliance are you using to host the netboot images?

I dont use a appliance or i am to tired to understand the question, I use OSX server to host the netboot images.
