Title: Windows 2003 AD

It is neither illogical nor un-safe to add a 2003 domain to a 2000 forest.  As was said, you'll have to prep the schema - but you'll have to do that anyways to update the existing domains at some point in time. So read up on the potential schema conflicts and fixes required to do the forestprep and you'll be very safe (also, you can even start leveraging the multi-edit features of the 2003 AD Users and Computers MMC running on an XP workstation against your 2000 domains...).   Whatever the reasons may be that Shawn needs a sub-domain, it is not illogical at all to start using 2003 to deploy it.  I could imagine he's in the middle of a rollout of a multi-domain forest and is just about to start rollout of the last domain (not uncommon at all - although in general I'd suggest for everyone to try to keep your AD infrastructure to a single domain forest, without a separate root domain...).  As such, it makes perfect sense to start rolling out that sub-domain with 2003 and when the time is right, update the other 2000 domains to 2003 also.   Quote from below "but you will not have the infrastructure in place on the parent to take advantage of the Child’s domain infrastructure" => I'm not sure what's meant by this.  I guess it referrs to the fact, that you can't switch to 2003 forest functional level at this time (obvious) and thus can't leverage some of the benefits 2003 brings to the table, which you don't get until you're at that level (e.g. LVR replication).   But there is a whole wealth of other benefits that you already gain in the 2003 sub-domain that makes it worth the effort (one of the main ones being promote from media, but also other things like quotas for object creation in the domain, UG group caching, DC Rename, Update logon timestamp attribute, User password on inetOrgperson to name a few).   So - go for it - if you do need a subdomain (which is a separate discussion), then yes, you're totally fine using 2003 (after doing your homework on the schemaprep for the 2000 forest).   /Guido From: Steve Shaff [mailto:[EMAIL PROTECTED] Sent: Samstag, 27.
