Going with a /24 when you're laying out a network just because its common and small doesn't really help anymore than picking a /16 out of the blue in the long run.
Migrating machines into new subnets is actually not that difficult if properly planned - I've been around that circuit quite a few times.

But if not selected initially it's too late to easily go back...

Do you understand my others post about your network ? Is you DC set up on its network interface with a 255.255.0.0 netmask ? Your setup will work fine from an AD point of view (dssite.msc) , but not an IP routing point of view if you are really using a 255.255.0.0 Regards, Mathieu CHATEAU http://lordoftheping.blogspot.com<http://lordoftheping.blogspot.com/> ----- Original Message ----- From: Brian Cline<javascript:parent.ComposeTo('[EMAIL PROTECTED]',%20'');> To: ActiveDir@mail.activedir.org<javascript:parent.ComposeTo('ActiveDir@mail.activedir.org',%20'');> Sent: Friday, January 26, 2007 10:19 PM 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.
