A DC can literally handle thousands of users...  The question is =
redundancy...  If the DC goes down, what will the users authenticate =
with?  If there are realitively few users (25 or less) and a decend link =
back to corporate, then consider only having 1 DC at the site... =
Otherwise, 2 at each site is good.  If you are/will be using Exchange 2k =
in distributed fashion, then keep in mind that it will hammer away at =
the GCs.  Each site will most like run DNS on the DCs.  This is assuming =
a single domain...  If you planning multiple child domain (Which I think =
is pointless) then you will need 2 DC for each site.

There are some AD sizing tools that can be found on Microsoft's site.

Another option, is to look at centralizing you IS resource,  move toward =
server based computing.  You'll be able to do more with less.

Subject: [THIN] Domain Controller Scalability



We are, for a variety of reasons, joining the Corporate Domain in =3D
Corporate Domain in California. We do not have any BDC's here in the =3D
Northeast (as in CT).

As such we are trying to determine scalability in terms of how many =
BDC's =3D
or the Active Diretory equivalent we should plan for.

There are 3 sites in CT - approximately 350 users in each site
Two in NY  ( About 50 miles apart- NYC and WhitePlains) about 75 users =
per =3D
site
One in NJ with about 400 users
Two in PA - smaller number of users
Two in AZ - one in Tuscon - one in Phoenix.

We currently have NDS replicas in each of these locations so we are =3D
thinking we neeed to do the same for BDC's to smooth out logins and =3D
authentication.

Is there some formula for the number of users that can be easily =
accomodate=3D
d per BDC ???

Thanks in advance for your input
