Windows 2003 (Pre-SP1/R2) vs Windows 2003 R2 DFS/DFSR

Ok,

I'm need to know what the differences are between the ORIGINAL release version of Windows 2003 Server and Windows 2003 R2 with respect to DFSR / DFS.

Speficially, I need to know if WINDOWS 2003 R2 uses the same ports that Windows 2003 ORIGINALLY used for DFS, or if the new DFS[R] does the same thing with fewer ports.

I'm configuring a firewall between two locations that will use DFSR with on a Windows 2003 R2 domain.  It appears that R2 changes how DFS[R] works.  I need to know SPECIFICALLY which ports are required for DFSR & DFS Namespace operation under WINDOWS 2003 R2!

I'm looking for someone who's configured WINDOWS 2003 R2 with DFSR and DFS Namespace to work through a firewall...

PLEASE DO NOT SEND ME LINKS TO MICROSOFT KB ARTICLES THAT ALSO LIST THE NON-R2 VERSION OF WINDOWS 2003 SERVER. I'M ONLY INTEREST IN WINDOWS 2003 R2 AND WHICH PORTS I NEED FOR THAT PRODUCT'S IMPLIMENTATION OF DFSR / DFS NAME SPACE.

(I posted this question before, and got a bunch of KB articles pertaining to Windows 2003 Pre-SP1...)

If nothing has changed, please indicate that.

This is a 500 point question, and I need it answered completely.

Thanks for the help, and good luck.

What you'll want to do is use the DFSRDIAG utility (with the StaticRPC switch) to manually configure a static port number for dfs replication. By default I believe it's set to 0...which allows for dynamic ports.

Once you've set the static port you can verify with 'dfsrdiag dumpmachinecfg' that the static port setting has stuck.

Once that's done it's off to the firewall!

(and obviously you'll want to do this on all servers that are handling DFSR traffic)

Yeah, I sorta figured that... is that ALL I need to do with R2?

Does it not use all of those ports that the Pre-R2 version used?   ...or is it completely different at this point?

I'm going to have a R2 DFS namespace, and I'm going to use DFSR...

That should be it (we did the same thing here at work). The Pre-R2 version simply used the Windows File Replication Service to handle DFS replication....so there was definitely more to it as far as AD/Sysvol and what not. The new DFSR service is its own entity that is solely responsible for file transfer and replication.

(the FRS is still around but is solely responsible for AD/Sysvol now)
