Is it possible to extend the Active Directory schema in a Windows 2003 DC (NOT R2) to support DFSR?

We're in the process of installing a brand new Windows Server 2008 Web cluster and we would like to synchronize some files between the servers. The problem is that the DC in the domain is an old Windows Server 2003 Standard (NOT R2) which apparently doesn't contain some extension to the AD schema. Is it possible to upgrade the schema without upgrading the DC servers to R2?

When I try to create a Replication Group on the 2008 Server I get the following message:

---------------------------
Error
---------------------------
srv.XXXXXX.XX: The Active Directory Domain Services schema on domain controller
activedc07.srv.XXXXXX.XX cannot be read. This error might be caused by a schema
that has not been extended, or was extended improperly. See Help and Support
Center for information about extending the Active Directory Domain Services
schema. Schema version 30 is not supported.
