Windows File Replication Service

Hi All,

I'm trynig to replicate some files off of a DC.  

The Destination server is configured properly as we have other servers replicating to it.  

When I try to add this particular DC to be replicated, I get an error message saying the DFS replication service is not installed.

The DC is running SP2, and I can see the File Replication Service is started as a service.  

I'm not sure of the upgrade path of this DC, whether R2 was installed on it or not.  When I tried to add the DFS like I did on the other servers, I didn't get that option.  

Can we apply R2 after SP2 has been done?  Is there a download to get R2 installed and do we even need R2 to accomplish this?

Any suggestions greatly appreciated.

R2 is not just an update, it is really a whole new licensed version.  So to answer your question you cannot upgrade without purchasing an R2 license.  In R2 the replication is done using DFS-R.  In pre-R2 replication was done using FRS.  The only way to get the two to replicate is by using FRS and you would lose the functionality that DFS-R has if you did this.

In this scenario we're just looking to strictly copy the files.  I noticed using the setup that there was a schedule where you could allocate bandwidth.  Does FRS have this?  What features are in DFS-R that FRS doesn't have?

Can you run Vanilla FRS on R2?

The main difference is that DFS in R2 can do Block Replication IE: if you have a 100MB file and you only change a small amount, it can replicate just the change and doesnt have to replicate the whole 100MB file.
