Active directory will use the most specific network address that applies to it. For instance, I set up a class-A address (or multiple in some companies) that applies to all of the network space of the company and assign that to the primary data center location. Then I start making more focused subnets that route clients / replication to more specific locations. That way you don't run into the issue where clients can't find their own subnet so choose a random DC. I have set up subnets all the way from 8 bit down to 32 bit as needed and it all works fine. -- O'Reilly Active Directory Third Edition - http://www.joeware.net/win/ad3e.htm
_____ From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Brian Cline Sent: Friday, January 26, 2007 4:20 PM To: ActiveDir@mail.activedir.org Subject: [ActiveDir] Overlapping AD Subnet Boundaries Say I create an AD subnet of 10.10.0.0/16 and assign it to our primary site, and another subnet as 10.10.41.0/24 and assign it to a secondary site. Will AD treat a client address of, say, 10.10.41.104 as a client on the secondary site, or will it default to the more general primary subnet? The reason I ask is we now have a need for a second AD site (I can see all the enterprise folks grinning now) and we have quite a number of other subnets that I'd have to manually enter if this is not the case. I don't mind doing it, but I was curious either way.
