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
netbooting Macs at their institution.
We are seeing instances where computers will intermittently fail while
trying 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 likelihood of failure. According to our network staff, all of the
appropriate ports 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 from unsuccessful connections than from
successful ones.
Thanks for your help!
Rachel
