How can I run DFS on a Windows 2008 server in a Windows 2003 domain?

I would like to implement DFS on my Windows 2003 domain. I first tried it on Windows 2003 Standard SP3 servers and encountered a 64 GB limit to what it is able to replicate. I was told that 2003 runs FRS for replication, but Windows Server 2008 uses DFS replication and has a much higher limit.

So next I installed DFS role services on a Windows 2008 R2 64 bit  Enterprise server. I tried to set up a domain-based DFS namespace but when I go through the "new name space" wizard, I get an error saying the namespace server cannot be added. The object identifier does not represent a valid object."

I have also set up a stand-alone namespace but am not able to get it to replicate. There are two targets for the stand-alone namespace. When I run the "replicate folder wizard, I get the following error:

"domain.com:The active directory domain services schema on Domain Controller  X cannot be read. This might be caused by a schema that has not been extended, or was extended improperly ..."

What must I do to get this working? Is it possible to run DFS on Win2008 servers in a Windows 2003 domain or must the domain first be upgraded to a Windows 2008 domain?

What if I create the domain namespace on a Windows 2003 server and then set up replication via the Windows 2008 DFS management console. Would that work?


Thanks for any help you can provide.

Thanks Araberuni, it looks like I will need to upgrade the schema to at least 2003 R2 in order to make this all work.  Otherwise I can create a stand-alone DFS namespace but file replication is not going to work.  Is that correct?  If I have to upgrade the schema,  I might as well go ahead and upgrade the schema to Windows  2008 R2. That would be no more work than upgrading to 2003R2.

You thoughts/comments?

To use the Windows Server 2008 mode, the domain and domain-based namespace must meet the following minimum requirements:

The forest uses the Windows Server 2003 or higher forest functional level.
The domain uses the Windows Server 2008 or higher domain functional level.
All namespace servers are running Windows Server 2008.

Raise your domain functional level to win2k3 or higher then you can configure dfs on win2k8
