Won't work unless you have a very small network. MAC addresses do not pass beyond the current collision domain.

That would also mess 'em up. :) From: Mayo, Bill [mailto:[email protected]] Sent: Wednesday, September 16, 2009 11:35 AM To: NT System Admin Issues Subject: RE: Block device from DHCP scope You should be able to setup a reservation for it, where the router/DNS and IP are all the same. That way the machine doesn't know how to get anywhere other than local. Naturally, this type of thing doesn't prevent someone from manually setting the IP config, but nothing you do in DHCP will.

I have a rogue IPhone that appears intermittently on my DHCP range. I haven't managed to find out who it is yet but if I do I will be sure to address it via HR....turning off the wireless unfortunately is not an option. I know the user could probably bang in some static settings to get around the block, but seeing as though our users can't save things in the right folders, I'm relying on them not being savvy enough to enter some network settings themselves. Thanks for all ideas... ~ Finally, powerful endpoint security that ISN'T a resource hog! ~ ~ <http://www.sunbeltsoftware.com/Business/VIPRE-Enterprise/> ~
