Brian,
This *may* be a little bit different in WIN2003 but here is how you do it in
WIN2000.
Create a Site for your first 'remote' subnet. Let's call this Miami.
Associate the 10.1.2.x subnet to the Miami Site.
Create a Site for your second 'remote' subnet. Let's call this one Atlanta.
Associate the 10.1.3.x subnet to the Atlanta Site.
Create a Site for your third 'remote' subnet. Let's call this one Columbia.
Associate the 10.1.4.x subnet to the Columbia Site.
Let's say that your HQ is in Charlotte. If you have not already done so,
create the 10.1.1.x subnet and associate it with the
Default-First-Site-Name. You can rename this to Charlotte if you so choose.
We are going to use the hub and spoke model. This is where Charlotte is the
hub and all of the Sites are connected to Charlotte. It would be a really
good idea to have a Firewall at the Charlotte Site that can handle multiple
VPNs as you should strongly consider creating a Site-to-Site VPN from
Charlotte to Miami and a second VPN from Charlotte to Atlanta and a third
VPN from Charlotte to Columbia. You would also need a Firewall at the three
remote locations that can handle the VPN ( doh ). Cisco and SonicWall have
some nice products.
You need to make sure that the Domain Controller in each Site has the proper
IP Address ( I am sure that you are using either a Reservation or a Static
IP Address for all of your servers ) and is located in the correct Site in
the ADSS MMC..
You would probably want to make each of the Domain Controllers a Global
Catalog Server as well. DNS would also be important. Probably DHCP as
well.
Please take a look at the following MSKB Articles on how clients locate a
Domain Controller:

http://support.microsoft.com/?id=314861
Our friend the KCC - with a little help from the ISTG - will make sure that
everything is done properly. However, it is extremely important that the
Sites and Subnets be set up and configured properly. The KCC uses this
information. The one thing that you would need to do would be to set up the
Site Links. There would already be one ( the DEFAULTSITELINK ) that is
partially set up. You would need to add the second Site ( you will see that
Charlotte is already there - you would simply add Columbia, for example ).
You would then set up another Site Link for Charlotte - Atlanta and a third
for Charlotte - Miami. You would need to create the Costs as well as the
Schedule and the Intervals associated with each Site Link. You will want to
think about bridging all Site Links.....
This is a pretty vanilla account of what you could do. We would need a lot
more information from you in order to give you a more appropriate response.
How many users are in each Site? What are the client OSes? What are the
connection speeds between each location? Do you want / need all Sites to be
linked to the others? You get the picture.
HTH,
Cary
