RE: [ActiveDir] Domain Controllers

[Debbie Ellis]

Thanks , the tools will be useful and I also found this info at Technet: Table 34 Domain Controller Capacity Planning Users in site Domain controller Global Catalog Dedicated DC? Server/Advanced Server < 100 One uniprocessor PIII 500, 512 MB Domain controller is a global catalog. No Server 101 – 500 One uniprocessor PIII 500, 512 MB Domain controller is a global catalog. Yes Server 500 – 1,000 One Dual PIII 500, 1 GB. Domain controller is a global catalog. Yes Server 1,000 – 10,000 Two Quad PIII XEON, 2 GB. Both domain controllers are global catalogs. Yes Advanced Server > 10,000 users One Quad PIII XEON, 2 GB for every 5,000 users. One global catalog for every two domain controllers with a minimum of two global catalogs. Yes Advanced Server Note The best practice guidelines for domain controller hardware are: ·                     For 100 to 200 sites use multiprocessor hardware. ·                     For >200 sites, consult the branch office documentation. ·                     For sites connected to 10 or more sites use multiprocessor hardware. ·                     For domains with > 50,000 users, use a Quad PIII XEON with 2 GB of memory for the dedicated PDC.       -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]] On Behalf Of Tony Murray Sent: Friday, January 24, 2003 10:16 AM To: [EMAIL PROTECTED] Subject: Re: [ActiveDir] Domain Controllers   You could also have a look at DirectorySim from NetPro.   http://www.netpro.com/products/directorysim/directorysim_c.cfm   Tony   ---------- Original Message ---------------------------------- From: "Tim Hines" <[EMAIL PROTECTED]> Reply-To: [EMAIL PROTECTED] Date: Fri, 24 Jan 2003 09:40:39 -0500   You may want to use adsizer.exe to determine this.

(W2K)  I know there are factors to take in account, such as network topology, other services running on the domain controller, etc.  I am referring to only a domain controller with no global catalog role.     List info   : http://www.activedir.org/mail_list.htm List FAQ    : http://www.activedir.org/list_faq.htm List archive: http://www.mail-archive.com/activedir%40mail.activedir.org/
