Yes you only need one DFS Root.
Make sure that you see the difference between DFS and Clusters. DFS only
hosts a replica of an USN namespace and provide fault tolerance by
automatically redirect the target to an available replica.
DFS in Pre-Windows Server 2003 R2 Scenarios supports replication between
targets. (servers hosting a root or link) by using FRS. File Replication
In Windows Server 2003 R2 and later DFS support replication by using DFS-R
(DFS Replication) DFS-R have many advantages over FRS so I recommend you to
go for Windows Server 2003 R2 directly.

I think I'm finally getting it. I was just going to do one server, but
I think I will also do another server also.
-I have 2 servers at the main site (Server01 and Server 02). I am
going to have 2 servers offsite (Server03 and Server 04).
-Server01 will replicate to Server03 (Server01 is nothing more than a
file server - which also has some applications on it).
-Server02 will replicate to Server04 (I work for a bank and we
currently image all our checks that we process and the data and images
of the checks are stored on Server02. It runs on a Progress database).
- Do I just need to set up 1 DFS Root (I hope I'm using the right
- How will having a database installed on Server02 affect the
fault-tolerance? My plan is to have the Progress database installed on
- The programs to access the database and the check images sits on
Server02, so if Server02 goes down, will DFS re-direct the
request to Server04 automatically?
- Would you recommend waiting til R2 is released before implementing
Thanks for the help, I appreciate it!
