You generally only need 1 dhcp server per subnet or if you have more you should make sure they have non-overlapping address pools. I actually made a wrapper script to this to actually warn me of rogue dhcp servers on the network after an incident with some clumsy person installing vmware with it's dhcp and sending a laptop off to the wrong subnet... so you might want to check why the second attempt says you had 3 DHCPOFFERS. </pre> </blockquote> <pre wrap=""> __________________________________________________ Do You Yahoo!?
