Don't forget also that when a broadcast goes out to a dhcp server whichever responds first is where that pc stays with, now, if too many hit the dhcp server you will simply 'get denied' it won't rebroadcast to another dhcp server. Just like dns, a negative response is still a response.
For this reason, I'm not crazy about the 80-20 rule. The last company that set it up had the exact problem I described and couldn't figure out why a bunch of workstations were not getting IP's. I suppose in very large networks this could be an issue, but if your dhcp server is down for more than the 8 day default (in windows), you have other issues more important I would presume ;) ~ Finally, powerful endpoint security that ISN'T a resource hog! ~ ~ <http://www.sunbeltsoftware.com/Business/VIPRE-Enterprise/> ~
