Oh, that's easy then. Kill your users.

(sort of like how printing works on novell networks) but unlike greg I don't use dhcp for servers nor do I wear mismatched socks, but we won't go there... ;¬) On Fri, Oct 23, 2009 at 3:21 PM, Nick Smith <nick@xxxxxxxxxxxxxxxxxx<mailto:nick@xxxxxxxxxxxxxxxxxx>> wrote: Wow.

I use DHCP for everything. printers, servers, access points, the works. But, I do it with reservations. We have shifting dns and wins servers, networks are often getting re-addressed, or we ship things around the WAN. DHCP reservations make it much more predictable and manageable.

Do hp jetdirects do this as well? Also wondering about whatever network component dell printers use too. Yes, we've had a couple of conflicts so wondering if I should enable the address conflict detection on the dhcp server or leave it alone. ________________________________ SUBJECT TO CONTRACT ________________________________ SUBJECT TO CONTRACT ________________________________ SUBJECT TO CONTRACT
