I've got DCs for domains in the tens-of-thousands of objects range that are running on 1GB (server core). Others in the same range need 4GB.
Depends, as always, on your applications and the load you are placing on the DCs. Regards, Michael B.

I'm sure every domain is different (in particular, I expect it's not really the size of the database, but requests/second (hmmm, I *should* benchmark *that*)), but this at least gives me some clue. > I'm sure Microsoft has a document about server sizing that directly > addresses the memory requirements for a size of a domain > somewhere, right? They do, it doesn't scale down this small. Capacity planning docs all seem to assume if you're asking these questions you must be in the 1000+ element range. I'm trying to scale in a different dimension than they anticipated. -- Ben ~ Finally, powerful endpoint security that ISN'T a resource hog! ~ ~ <http://www.sunbeltsoftware.com/Business/VIPRE-Enterprise/> ~ --- To manage subscriptions click here: http://lyris.sunbelt-software.com/read/my_forums/ or send an email to [email protected] with the body: unsubscribe ntsysadmin ~ Finally, powerful endpoint security that ISN'T a resource hog! ~ ~ <http://www.sunbeltsoftware.com/Business/VIPRE-Enterprise/> ~ --- To manage subscriptions click here: http://lyris.sunbelt-software.com/read/my_forums/ or send an email to [email protected] with the body: unsubscribe ntsysadmin
