The 20 is designed to keep you alive and running while you fix the 80 server. Certainly a full range on both servers to serve all your clients would be great, if your subnetting and available addresses allow it. > > 2) Let's say everything is working perfectly and both DHCP servers are > up.

It does not do a brand new lease broadcast. It will continue to ask directly until it gets an answer. If it can't it will then broadcast for a brand new lease. ~ Finally, powerful endpoint security that ISN'T a resource hog! ~ ~ <http://www.sunbeltsoftware.com/Business/VIPRE-Enterprise/> ~
