Hi Rachel!
There are quite a few reasons why this wouldn't be working. I've worked wit=
h these setups for over 5 years now - happy to lend a hand offline :). Feel=
free to forward (or reply all if you'd prefer):
Server/Client OS
Deployment type (NetBoot, NetInstall, 3rd party tool or utility)
Any relevant portions of the logs you are seeing
Best,

Subject: Netboot Issues
Hi all,
Apologies if you receive this multiple times, since I'm cross-posting to a =
few lists.
I'm wondering whether anyone has seen (and resolved) a similar issue netboo=
ting Macs at their institution.
We are seeing instances where computers will intermittently fail while tryi=
ng to netboot, but will work on subsequent attempts. This might happen for =
10 of 20 computers in a lab, or it might happen for one individual computer=
; the number of machines being connecting doesn't appear to affect the like=
lihood of failure. According to our network staff, all of the appropriate p=
orts are enabled for NetBoot: https://support.apple.com/en-us/HT203437. We =
aren't seeing anything that gives us any help narrowing down the source of =
the problem. The only hint is that the Netinstall log shows fewer packets f=
rom unsuccessful connections than from successful ones.
Thanks for your help!
Rachel
