mirroring windows 2003 server r2 dfs

Hello Experts,
Actually I do have a file server that also acts as domain controller were all the network stations has it desktops (Win Xp) stored as remote.

The server is running Windows 2003 R2

I would like to install a new server that works as domain controller backup were all the date from main server it`s being duplicated and in case of bad function my network could be working properly.

This is an small business with about 10 workstations and  the software for all the accounting operations are based on this server either.

I had read about DFS

Any of you could let me know some basic steps to be folloed in roder to achieve my goal without affecting my operating server and it`s services.

Your help will be kindly appreciatted.

Thanks in Advace

The first job would be to install a new sever and then use DCPROMO to make it a second DC.
From the command line promote the new machine to a domain controller with the DCPROMO command from the command line
Select Additional Domain Controller in an existing Domain

Assuming that you are using Active Directory Integrated DNS on the first Domain Controller, Just install DNS on the new DC (from the control panel->Windows Components->Networking Services->DNS, or Configure my server wizard), DNS will then replicate to the new domain controller along with Active Directory.

To make the new machine a global catalog server, go to Administrative Tools, Active Directory Sites and Services, Expand, Sites, Default first site and Servers. Right click on the new server and select properties and tick the Global Catalog checkbox. (Global catalog is essential for logon as it needs to be queried to establish Universal Group Membership)

If you are using DHCP you should spread this across the domain controllers, In a simple single domain this is easiest done by Setting up DHCP on the second Domain controller and using a scope on the same network that does not overlap with the existing scope on the other Domain Controller. Dont forget to set the default gateway (router) and DNS Servers. Talking of which all the clients (and the domain controllers themselves) need to have their Preferred DNS server set to one domain controller, and the Alternate DNS to the other, that way if one of the DNS Servers fails, the clients will automatically use the other,

Both Domain Controllers by this point will have Active Directory, Global Catalog, DNS and DHCP. and the domain could function for a while at least should any one of them fail. However for a fully robust system you need to be aware that the first domain controller that existed will by default hold what are called FSMO Roles. There are five of these roles that are held on a single server and are essential for the functioning of the network. If the second Domain Controller fails, then no problem as the FSMO roles are on the first Domain Controller. However if you intent to function with the second Domain Controller only, then the roles need to be moved to the Second Domain Controller. Ideally if this is a planned event you should cleanly transfer the FSMO roles, if it is an unplanned emergency the FSMO roles can be seized (see http://support.microsoft.com/kb/255504)

Once thats done then you need to impliment DFS if you want to replicate the data. Server 2003R2 has a much improved DFS over the original 2003 server - start here http://www.windowsnetworking.com/articles_tutorials/Implementing-DFS-Replication.html

he said small business :P

use acronis trueimage to make a "ghost" of your server on a usb drive or any other drive

or use seagate backup exec, it can backup all users and server config

The user says he wahts to use DFS. If you want to use DFS then you need to have two servers. If you bother to read the question the user says he wants a second server to be an additional DC and to replicate the data to - ghosting is NOT a suitable solution here.
