Title: Exchange rollout - How much larger does NTDS.DIT become?

To further add to this, it depends considerably on how populated you want your GAL to be. Some people just let the mandatory Exchange attributes get populated, others want the GAL to be the one stop shop for info on employees so everything goes into the GAL which means everything goes into AD.   -- O'Reilly Active Directory Third Edition - http://www.joeware.net/win/ad3e.htm      From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Grillenmeier, Guido Sent: Friday, July 28, 2006 4:41 AM To: ActiveDir@mail.activedir.org Subject: RE: [ActiveDir] Exchange rollout - How much larger does NTDS.DIT become? Assuming this is after defrag, 650MB without Exchange is quite a large AD – guess you’d be close to 100k users in your forest, if you’ve used the “standard” attributes of the objects in AD (and haven’t added stuff like thumbnail pictures to your users…).   After adding the Exchange schema mods, the DIT shouldn’t grow substantially, since AD doesn’t use any space for unused attributes – and the Exchange attributes for your object won’t be filled magically, until you mail-enable them. But once they are filled, it will impact your AD (e.g. E2k3 adds 130 attributes to the Public Information property set used by user class objects)   It is very tough to make a guess at the actual size you’d have with a fully deployed Exchange, but if you do mail-enable the majority of your users (i.e. give them Exchange mailboxes) and add DLs etc. and assuming my guess with 100k users is in the right ballpark your AD DIT would easily grow to 3-5 GB.   /Guido   From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of RM Sent: Thursday, July 27, 2006 6:46 PM To: ActiveDir@mail.activedir.org Subject: [ActiveDir] Exchange rollout - How much larger does NTDS.DIT become?   NTDS.DIT is currently 650megs.  Once Exchange has been fully deployed, any guesses as to how much larger it will become?  Just looking for a ballpark figure... thx, RM
