When we migrate our production DCs to Server 2008 I would also like to move away from FSR to DFS-R for SYSVOL replication. My problem is that I setup a quick lab to test it out but it's not going as planned. I'm sure I'm just overlooking something obvious but I can't seem to figure out what :)

Here's what I'm doing 1. Installed two server 2008 machines (R2) and promoted them to domain controllers - with Server 2008 (Not R2) being the forest and domain functional levels.

  1. Verify that standard replication is working by placing some stuff in SYSVOL and make sure it ends up on the second domain controller.

  2. I then attempt to start the DFS-R migration process but dfsrmig.exe /setglobalstate 0 or dfsrmig.exe /setglobalstate 1 both report that I'm already at stage 3 ('Eliminated')..

So what am I missing?

From the SYSVOL Replication Migration Guide: FRS to DFS Replication

http://technet.microsoft.com/en-us/library/dd640019.aspx

Windows 2000 Server and Windows Server 2003 use File Replication Service (FRS) to replicate SYSVOL, whereas Windows Server 2008 uses the newer DFS Replication service when in domains that use the Windows Server 2008 domain functional level, and FRS for domains that run older domain functional levels.

So... the error message is right, you're already using DFS :)

I was hoping this was the answer - just couldn't find any documentation to prove it :) .. Thanks. –  GNUix Jun 12 '09 at 7:22

Your lab is not accurately simulating your production environment, unless I'm missing something.

You refer to migrating to 2008 DCs, implying that you are currently running 2003 or below, so your lab should be configured with 2003 DC(s) and then add one or more 2008 DCs.

correct - however I'm not trying to simulate my production environment. I'm only trying to simulate moving from FRS to DFS-R for SYSVOL replication. It is my understanding that even in a 100% server 2008 environment FRS is used by default, is this not the case? –  GNUix Jun 12 '09 at 6:18
    
If the domain is running at the 2008 functional level, then it's using DFS-R for SYSVOL. If you had just dcpromo'd your 2008 servers and not raised the domain/forest functional level, you would've been using FRS for SYSVOL replication. –  ThatGraemeGuy Jun 13 '09 at 7:55
