I've run into this behavior a couple times after updates / upgrades. One
time i went to older version of tftp and /tftpdir/lts to fix it. The other
time the problem was with messed up /etc/hosts file and system inability
to resolve the workstation names. Fixing /etc/hosts took care of the
problem.
yet another option is to create boot files for every terminal - notice
that the search for boot file starts with a name based on full mac
address.
Good luck, julius
