1. Yes this is fine and often recommended. Best to keep as few subnets as possible just for the simplicity of it all and ongoing maintenance.
2. You could either carve out a little portion of the subnet for these machines or move them to another "clean" IP segment or even just configure the machines directly to use the specific site that you want them to use. If you set the value of HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Netlogon\Parameters\Sit eName to a specific site it will ignore the subnet/site topology for determining the local machine's site. This can be messy/confusing especially if people forget about it but I have found occasion to use it in a couple of deployments where changing a machine's IP address was NOT an option but I wanted the machines to be using a very specific set of GCs. Yes, the application involved was Exchange. :) joe -- O'Reilly Active Directory Third Edition - http://www.joeware.net/win/ad3e.htm -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Burns, Clyde R. Sent: Tuesday, April 04, 2006 11:07 AM To: [email protected] Subject: [ActiveDir] AD sites and subnet questions I am planning a move of our exchange servers and two domain controllers out of our current single site to a new separate site. We had MS come in and do a healthcheck on Exchange, and its one of their recommendations. We don't have all the subnets in our network added into the current site yet. Before I break out the netsh and AD cookbook scripts and go to the lab I wanted to first see if there are simpler ways of doing this. Question 1. If I have say, 25 class C networks like 192.168.1.0/24 thru 192.168.25.0/24 in site 1. Can I put 192.168.0.0/16 under site 1 and it work the same as explicitly defining the 25 separate subnets? Question 2. The computers going to site 2 are part of a subnet in site 1 currently. Can I get away with adding individual computers to site 2 that are subset of a subnet defined in site 1? Site 1 - 192.168.1.0/24 Site 2 - 192.168.1.10/32 192.168.1.11/32 192.168.1.12/32 192.168.1.13/32 Or do I need to move them into their own subnet for the separate site? Thank you for any insight and/or recommendations you have.
