Why the 2 separate DHCP servers, if there's so few clients? Why not just have one, with a scope that uses all the addresses? Or even a second scope on the one server, if you want to maintain those separately? Joe Heaton

Like I said there are a handful of computers that have been on the 2nd dhcp for sometime, but I think this is from their migration a couple of weeks ago and of course once a device 'checks in' it will stay on that server as long as its responding. ________________________________ From: Damien Solodow [mailto:[EMAIL PROTECTED] Sent: Tuesday, February 19, 2008 10:38 AM To: NT System Admin Issues Subject: RE: DHCP understanding The main question is are the requests getting to the second dhcp server? Is it on a different subnet? If it's a windows dhcp server, is it authorized in AD? From: Benjamin Zachary [mailto:[EMAIL PROTECTED] Sent: Tuesday, February 19, 2008 10:34 AM To: NT System Admin Issues Subject: DHCP understanding I have a client that has 2 dhcp servers in his AD. Both work to some extent, a few users are on the 2nd dhcp server, I think occurred during their migration, but most of the users are on the primary dhcp server. Each dhcp server has its own scope 50-100 and 101-150 for example. His primary is full, all 50 ips are in use, and new computers coming onto the network are not getting an IP. I understood dhcp to be along the lines of a negative response is still a response (like dns) whereas the client broadcasts out server1 responds and says I have no IP's and the box says ok Im done I don't get an IP. Their consultant is arguing this is not the case by the fact that 5 or 6 computers are on the 2nd dhcp server, even though 20 other computers are not receiving dhcp requests. I tried to get into the 'call home' function of dhcp and once your on the server you would remain there etc etc but this is more of a friend thing so Im trying not to just tell the guy he is flat wrong until Im more sure. ~ Upgrade to Next Generation Antispam/Antivirus with Ninja! ~ ~ <http://www.sunbelt-software.com/SunbeltMessagingNinja.cfm> ~
