Brand new PC's. Turned on PXE boot and altered the boot order.
Went into ZISEDIT and set the COMPUTER NAME and set DHCP to on ('off' is
a stupid default!).
We multicasted from a master to 36 clients, then rebooted the clients.
About 8 of them didn't go through the rename process. We checked the ZIS
data on those 8, and ALL of them had the master computer's name written
to ZIS instead of the other way around.

What the heck is going on here!?!
