Troubleshooting problems with DFS Replication diagnostic report accessing performance counters - The Storage Team at Microsoft - File Cabinet Blog
A blog reader recently reported that running a diagnostic report resulted in the following error: The DFS Replication service is unable to access the performance counter DFS Replicated Folders(Apps-{B0CFA463-027A-47BE-B1B8-8A84D5C758F2})\File Installs Succeeded on SERVER1. Performance data is unavailable.
This article describes how to manually rebuild the performance counter library values. Important This section, method, or task contains steps that tell you how to modify the registry. However, serious problems might occur if you modify the registry incorrectly. Therefore, make sure that you follow these steps carefully. For added protection, back up the registry before you modify it.

Optimizing File Replication over Limited-Bandwidth Networks using Remote Differential Compression
Optimizing File Replication over Limited-Bandwidth Networks using Remote Differential Compression Dan Teodosiu, Nikolaj Bjorner, Joe Porkka, Mark Manasse, and Y. Gurevich November 2006 Remote Differential Compression (RDC) protocols can efficiently update files over a limited-bandwidth network when two sites have roughly similar files; no site needs to know the content of another's files a priori.
How to configure DFSR file-type compression in Windows Server 2008
This article describes how to configure Distributed File System Replication (DFSR) file-type compression in Windows Server 2008. In Windows Server 2008, you can use DFSR to configure the compression of files by file type. This differs from the version of DFSR in Windows Server 2003 R2. In Windows Server 2003 R2, DFSR has the following hard-coded extension list: .wma .wmv .zip .jpg .mpg .mpeg .m1v .mp2 .mp3 .mpa .cab .wav .snd .au .asf .wm .avi .z .gz .tgz .frx Notes File compression in DFSR uses the XPRESS compression format in the DFSR staging area. XPRESS compression differs from Remote Differential Compression (RDC).
Ned here again. Today I’m going to talk about a couple of scenarios we run into with the ConflictAndDeleted folder in DFSR. These are real quick and dirty, but they may save you a call to us someday. Scenario 1: We need to empty out the ConflictAndDeleted folder in a controlled manner as part of regular administration (i.e. we just lowered quota and we want to reclaim that space). Scenario 2: The ConflictAndDeleted folder quota is not being honored due to an error condition and the folder is filling the drive.

How to configure DFS to use fully qualified domain names in referrals
A Windows 2000-based server that is using Microsoft Distributed File System (DFS) replies to a DFS "get referral" query with a NetBIOS name format (\\ \ ) by default. This is necessary in certain environments in which NetBIOS is relied upon. Depending on the client's Domain Name System (DNS) configuration, the client may not be able to resolve the server name returned from the DFS "get referral" query. Important This section, method, or task contains steps that tell you how to modify the registry. However, serious problems might occur if you modify the registry incorrectly.If you’re still using an older file and folder replication solution, it’s high time you moved over to the Distributed File System. The Distributed File System (DFS) has been around since the days of Windows NT. It comes in a variety of configurations and options and is available in standalone and domain configurations. DFS is a popular and effective technology that provides redundant file and folder replication between remote servers. You can organize them under a common namespace to let users connect without needing the name of the server on which the DFS share is hosted. Unfortunately, there has never been a comprehensive DFS best practices document.
Windows: Make the Move to DFS
My previous blog post explained how to configure the DFS Replication management pack . The backlog monitoring feature of the management pack is disabled by default and requires some additional configuration. This blog post explains how to enable backlog monitoring using the DFS Replication management pack and also describes how to override some of the default configuration settings in the management pack.

Under Windows 2003/2008, to generate a diagnostic report for DFSR Replication, follow this easy steps: Click Start, point to Administrative Tools, and then click DFS Management: In the console tree, under the Replication node, right-click the replication group that you want to create a diagnostic report for, and then click Create Diagnostic Report: Follow the instructions in the Diagnostic Report Wizard, as in the pics below:

DFSR Does Not Replicate Temporary Files - TechNet Articles - Home - TechNet Wiki
This topic was originally posted to the AskDS blog and has been added to the wiki to allow for community editing. If you notice that DFS Replication (DFSR) is not replicating certain files, one simple reason is that the temporary attribute is set on them. By design, DFSR does not replicate files if they have the temporary attribute set on them, and it cannot be configured to do so. This may not be obvious because nearly all the normal methods you would use in Windows to check file attributes do not show the temporary attribute.
Understanding DFS Replication "limits" - The Storage Team at Microsoft - File Cabinet Blog
[Updated on 11/27/06 to clarify areas where customers commonly have questions] The most frequent DFS Replication questions are about replication limits. The answer is, as you might guess, not as simple as some arbitrary hard-coded limit. And just so we’re on the same page, I’m talking about the new replication engine in Windows Server 2003 R2, not File Replication Service. :-) Let’s start with the published tested DFS Replication limits:Welcome to the design guide for the Distributed File System solution in the Microsoft® Windows Server™ 2003 R2 operating system. This preliminary guide contains design recommendations for two scenarios, data publication and data collection, in which DFS Namespaces and DFS Replication are commonly used. (Additional recommendations and scenarios will be available as they are developed.) This guide is intended for IT planners and architects who are evaluating these technologies or creating a distributed file system design for their organizations. If you are not familiar with DFS Namespaces and DFS Replication in Windows Server 2003 R2, we recommend that you read the document titled "Overview of the Distributed File System Solution in Windows Server 2003 R2" available on the Microsoft Web site (http://go.microsoft.com/fwlink/?LinkId=55315).

How to manually decommission a root server that hosts a domain-based DFS root in Windows Server 2003
This article discusses how to decommission a root server that hosts a domain-based Microsoft Distributed File System (DFS) root in Microsoft Windows Server 2003. To decommission a root server that hosts a domain-based DFS root, follow these steps: Remove the root server from the DFS namespace. To do this: Use the Distributed File System snap-in to remove the root server from the DFS namespace. To do this: Click Start , point to All Programs , point to Administrative Tools , and then click Distributed File System .DFSR Administration
The following table describes the groups that can perform basic DFS Replication tasks by default and the method for delegating the ability to perform these tasks. To view the delegation list for a replication group in the console tree, select the replication group, and then click the Delegation tab in the details pane. If you plan to delegate the ability to create and administer replication groups, consider the following:
