As others have pointed out, helper addresses on your layer3 switch(es) will do most of the work for you - getting all of your DHCP requests to a central DHCP server with multiple scopes is pretty much the right approach. If your environment were much larger, one or more of these might help, and I'm putting them out there just for FYI sake: The reply by aichainz in this thread is useful - http://ask.slashdot.org/article.pl?sid=06/04/26/2251224 I've looked at these packages before, but have never had a chance to implement any of them: http://www.net.cmu.edu/netreg/ http://www.solarwinds.com/ http://freshmeat.net/projects/ipplan HTH Kurt ~ Finally, powerful endpoint security that ISN'T a resource hog! ~ ~ <http://www.sunbeltsoftware.com/Business/VIPRE-Enterprise/> ~
