SO you are concerned about overall load then. This is something that is addressed in larger orgs often by segregating the PDC off in its own logical site which is hung off the main site it would normally be part of. That means it will usually not be used for autocoverage of other WAN sites and it will not become a large site bridgehead[1] and naturally avoided by any Exchange in that site if Exchange for some reason decides to beat on it due to some bad decision by an Exchange admin during configuration. This is especially helpful if you have a large legacy client load or lots of stupid applications that are using the old NET API (or WinNT provider) primarily which already overly target PDCs.
joe [1] I recall asking way back at the 2003 RAP/RDP conference for a switch to say use all DCs but these special ones for bridgeheads, I would rather manage exceptions than manage the ones that are the ones to be used. Best is to be able to specify either way. -- O'Reilly Active Directory Third Edition - http://www.joeware.net/win/ad3e.htm -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Carlos Magalhaes Sent: Wednesday, May 17, 2006 9:44 AM To: [email protected] Subject: Re: [ActiveDir] DNS on a DC or NOT Let me put that into perspective (and from reading the post again I thought it came across), the blog entry refers to networks with a large client load. I don't mean do NOT have DNS on your server it recommends (Option 2) releasing some of the load with the two registry settings, i.e. *LdapSrvPriority *and *LdapSrvWeight*.which is explained in the entry :) These settings I have only ever used on large networks when I have noticed a large amount of DNS traffic being routed to the PDC DNS Service. :) Does that explain the post if not just let me know what more information you need and I will explain it :) Carlos Magalhaes ASB wrote: > Which blog entry... > > -ASB > > > On 5/17/06, *Krenceski, William* <[EMAIL PROTECTED] > <mailto:[EMAIL PROTECTED]>> wrote: > > I was reading Carlos's blog about not running DNS on the PDC > emulator.
