Hello,

Looking to implement DFS and its replication features on a group of Server
2008 machines.... is Active Directory required to be able to utilize the
replication feature(s)?

James,
No, AD is not require and remember to install the DFS replication service.
You can have a stand-alone dfs namespace. but the drawback to this is that
you will have no fault tolerance except you use Server clusters, as opposed
to using the domain based dfs namespace.

Hi Isaac, thanks for the reply, I appreciate it.

could you elaborate a little on how AD provides fault tolerance for DFS?
This will be my first DFS implementation and I'm not clear yet on all the
details.... I'm thinking if I'm replicating/mirroring a share between two
servers, both those servers will need to have DFS(R) services installed,
wouldn't they both also hold the config info for the namespace? I obviously
don't know what I'm doing yet for this so any further detail would be much
appreciated.

thanks agian

James,
Domain based namespace provide fault tolerance because you can have multiple
domain controllers in your environment have the same dfs namespace, thus, if
one domain controller is offline, it willl have no effect on the dfs because
the others will still be there with the shares for clients to access. For
example, let's say you have a namespace called mydomain.com\shared. You can
setup fault tolerance on the other DCs using the same share folder "shared"
thus you will multiple servers with the shared folder having same data, thus
if one os offline, it makes no difference.
Likewise if you have a stand-alone dfs namespace, you will need to have a
namespace with a cluster resource.

Hi Isaac,

I just came across this in the DFS help system in server 2008:
"Ensure that all servers in a replication group are located in the same
forest. You cannot enable replication across servers in different forests."

It was in a requirements checklist for setting up replication... is this
information outdated perhaps? or is AD really required then?

I'm wondering if this info was from the 2k3 version of DFS and never updated
in server 2008

James,

Let me clarify my previous statement, Stand-alone dfs does not support
automatic file replication. Without AD you will need to use a third party
tool for replication. The statement below is correct, I understand it is
meant if you decide to use Domain based Namespace for DFS. To enjoy the full
benefit of DFS, it is suggested you use the domain based dfs namespace which
require AD.

I think you will benefit greatly from reading "How DFS Works"
http://technet.microsoft.com/en-us/library/cc782417.aspx it is quite an easy
read for the most part. It explains not only the setup and pre-requisites but
how DFS actually does its job. You will find for example that DFS name space and
DFS Replication are independent services that work together. You do not need DFS
Replication for DFS Name space and you can also use DFS Replication without
having a DFS Name space. They are just normally used together.

Do not put any data in the DFS root folders, use Links. If you read "How DFS
Works" you will understand why this is a better design.
