Man I suppose that you have 2 dhcp servers running....
maybe thats is the problem...
Your client target to other dhcp server that no have the option to handle
old isa netcards...
I have long time ago this ttrouble.... A router has a dhcp server too... and
when ltsp boot ask for second time dhcp appear this error: no nic... kernel
panic... etc etc...
The presence of other dhcp server running is the problem...
I try to help with my little acknoweldge...
Greetings.
