SO... I have to flood my network with broadcast traffic or pay the microsoft
extortion... Bill strikes again!
Thanks for that. I had been reading the dhcp man page (I should say book! What
a long one.) I guess I missed that. I'll have to set any Vista clients to
named hosts so I can limit the traffic.
According to that man page, ISC implies that Vista is broken, and Microsoft
implies that ISC is broken. Were playing the blame game again!
How fun! ;-P
