On from my DNS query, we have run into a problem that I saw coming but need to try and fix before we spend lots of money calling in CSE to do for us: we have a split site computer network. My Systems Manager wants to keep our new "lower" site separate from our managed "upper" site, and to do this we have to dat installed a separate server, used local profiles with redirected folders etc., and it runs nice.
The "problem" occurs when we RIS image the systems. They don't know where to get their DHCP address from (the upper site server or the lower site server). This shows itself in lack of ability to browse to the REMINST folder all the way to not even seeing the server on the LAN at all!
I'm aware that you aren't "supposed" to run two DHCP servers on the same LAN. I told them this a while ago while planning was taking place. But no-one listens and they want what they want.
My solution would be to have CSE come in and make the LAN one contiguous space (install the server as a member of the upper site network etc). The Sys. Manager is reluctant and wants to try different solutions next week. We have exactly one week to decide what to do before things start getting critical mass.
All that said (sorry for the length), I want to know:
(a) If running two separate DHCP servers (with different subnets) on the same LAN is possible and can work, and
(b) How to make it work. Can I use prestaging of the clients in the AD and then RIS? Can I block DHCP broadcast requests on our switches so that DHCP requests don't travel across sites? Or is there another way?
Any advice via PM, email, or on the forum would be greatly appreciated.
