Run DFSMGMT.MSC, browsing and clicking your way through adding the servers and their local configurations. No. No. . No. When a conflict occurs, DFS Replication logs an informational event to the DFS Replication event log. With tabbed autocomplete, parameters always in the same order, mandatory parameters where required, and everything else opt-in, it is very easy to pick up and start working right away. I start to poke around in DFSMGMT and see that undoing all these little nuggets is going to be a real pain in the tuchus, as there are hundreds of customizations. Best Regards, David Shen DFS Replication relies on Active Directory Domain Services for configuration. And if you used DFSMGMT.MSC, youd have to navigate through this: With the underlying DFSR Windows PowerShell , you now have very easy scripting options to tie together cmdlets into basic do everything for me with one command functions, if you prefer. To upgrade or replace a DFS Replication member, see this blog post on the Ask the Directory Services Team blog: Replacing DFSR Member Hardware or OS. You can force replication immediately by using DFS Management, as described in Edit Replication Schedules. These objects are created when you update the Active Directory Domain Services schema. In addition, DFS Replication has its own filter mechanism for files and folders that you can use to exclude certain files and file types from replication. 2. To secure data transfers across the Internet, the DFS Replication service is designed to always use the authentication-level constant, RPC_C_AUTHN_LEVEL_PKT_PRIVACY. For more information, Testing Antivirus Application Interoperability with DFS Replication (https://go.microsoft.com/fwlink/?LinkId=73990). Now: Finally, I added the memberships that enable replication and specify the content to replicate, using only two commands instead of three. Its not surprising if youre wary. However, when using RDC, the amount of data transferred is proportionate to the size of the ACLs, not the size of the entire file. DFS Replication does not continue to stage files outside of scheduled replication times, if the bandwidth throttling quota has been exceeded, or when connections are disabled. Yes. Propagation shows you if files are being replicated to all nodes. The conflict could reside on a server different from the origin of the conflict. Yes. You must be a registered user to add a comment. 2. For example, if all logon scripts were accidentally deleted and a manual copy of them was placed back on the PDC Emulator role holder, making that server authoritative and all other servers non-authoritative would guarantee success and prevent conflicts. If two users modify the same file at the same time on different servers, DFS Replication moves the older file to the DfsrPrivate\ConflictandDeleted folder (located under the local path of the replicated folder) during the next replication. Run the following command from an elevated command prompt on the same server that you set as authoritative: You'll see Event ID 4602 in the DFSR event log indicating sysvol replication has been initialized. Lets make that happen: That was painless I dont have to figure out the server names and I dont have to whip out Calc to figure out that 32GB is 32,768 megabytes. Connection ID: CD2A431C-8A5B-4A2F-93D7-E45CA0F0E368 Files may be replicated out of order. Facepalm. 4 You can use the Get-Acl and Set-Acl cmdlets in tandem with the Get-AdObject Active Directory cmdlet to configure delegation on the RG objects. No! For example, DFS Replication uses time stamps to determine which file takes precedence in the event of a conflict. If setting the authoritative flag on one DC, you must non-authoritatively synchronize It led to a charter for our Windows PowerShell design process: 1. Checking domain controller configuration DFS Configuration Heres a simple example put together by our Windows PowerShell developer, Daniel Ong, that shows this off: Its pretty nifty, check out this short demo video. The only reparse points replicated by DFS Replication are those that use the IO_REPARSE_TAG_SYMLINK tag; however, DFS Replication does not guarantee that the target of a symlink is also replicated. Files are also staged on the receiving member as they are transferred if they are less than 64 KB in size, although you can configure this setting between 16 KB and 1 MB. While were on the subject of ongoing replication: Tell me the first 100 backlogged files and the count, for all RFs on this server, with crazy levels of detail: Tell me the files currently replicating or immediately queued on this server, sorted with on-the-wire files first: Compare a folder on two servers and tell me if all their immediate file and folder contents are identical and they are synchronized: Tell me all the deleted or conflicted files on this server for this RF: Wait, I meant for all RFs on that computer: Tell me every replicated folder for every server in every replication group in the whole domain with all their details, and I dont want to type more than one command or parameter or use any pipelines or input files or anything! If you're concerned about multiple people editing the same file, we recommend using Windows SharePoint Services. Yes, DFS Replication can replace FRS for SYSVOL replication on servers running Windows Server 2012 R2, Windows Server 2012, Windows Server 2008 R2, or Windows Server 2008. In addition, some resources are harder to estimate. If the file is changed before DFS Replication begins transmitting the file, then the newer version of the file is sent. If making any DC authoritative, the PDC Emulator as authoritative is preferable, since its sysvol replication contents are most up to date. For information about Backup and Recovery functionality in Windows Server2008R2 and Windows Server2008, see Backup and Recovery. I went ahead and rebooted SSDC01 just for fun, and on DC02 it says its opened an inbound connection in the event logs. Consequently, there are custom DFSR replication schedules all over the connections and RGs. We then devoted ourselves to this, sometimes arguing late into the night about a PowerShell experience that you would actually want to use. Yes. To overwrite the configured schedule, use the WMI method ForceReplicate(). How to perform an authoritative synchronization of DFSR-replicated sysvol replication (like D4 for FRS) If only repairing one DC, make it non-authoritative and don't touch other servers. Upgrade to Microsoft Edge to take advantage of the latest features, security updates, and technical support. Yes. However, if the DFS Replication database on the server subsequently suffers irreversible corruption or data loss, the server attempts to perform an initial replication as the primary member instead of recovering its data from another member of the replication group. 1: Initialized 2: Initial Sync 3: Auto Recovery 4: Normal 5: In Error You can also check the backlog using this command: dfsrdiag backlog /rgname:REPGroup1 /rfname:REPFolder1 /smem:SendingServer01 /rmem:ReceivingServer01 You can run this command any time to force an update in the DFS replication event log to see if the status has changed: If the connection goes down, DFS Replication will keep trying to replicate while the schedule is open. How to force an authoritative and non-authoritative synchronization for DFSR-replicated SYSVOL (like "D4/D2" for FRS), https://support.microsoft.com/en-us/kb/2218556, Please remember to mark the replies as answers if they help and unmark them if they provide no help. Force sysvol replication. For more information about how to specify the RPC Endpoint Mapper, see article154596 in the Microsoft Knowledge Base (https://go.microsoft.com/fwlink/?LinkId=73991). Then let the changes replicate to the destination servers. The reparse tag and reparse data buffers are not replicated to other servers because the reparse point only works on the local system. By default, a maximum of 16 (four in Windows Server2003R2) concurrent downloads are shared among all connections and replication groups. For more information about why .pst files cannot be safely accessed from across a network, see article 297019 in the Microsoft Knowledge Base (https://go.microsoft.com/fwlink/?LinkId=125363). However, DFS Replication does replicate folders used by non-Microsoft applications, which might cause the applications to fail on the destination server(s) if the applications have interoperability issues with DFS Replication. These are major pitfalls to DFSR administrators, especially when first learning the product. No. Next, run the following command from an elevated command prompt on the same servers that you set as non-authoritative: DFSRDIAG POLLAD. Run the following command from an elevated command prompt on the same servers that you set as non-authoritative: You'll see Event ID 4114 in the DFSR event log indicating sysvol replication is no longer being replicated. replication group that you want to create a diagnostic report for, and then. As a result, various buffers in lower levels of the network stack (including RPC) may interfere, causing bursts of network traffic. If Remote Differential Compression (RDC) is disabled on the connection, the file is staged unless it is 256KB or smaller. If setting the authoritative flag on one DC, you must non-authoritatively synchronize all other DCs in the domain. Here is the example: This ensures that the RPC communication across the Internet is always encrypted. This occurs because Windows applies the System and Hidden attributes to the volume root folder by default. No. In the File Replication Service (FRS), it was controlled through the D2 and D4 data values for the Bur Flags registry values, but these values don't exist for the Distributed File System Replication (DFSR) service. For more information, see DFS Replication Initial Sync in Windows Server 2012 R2: Attack of the Clones. The initial replication does not need to replicate contents when files differ only by real attributes or time stamps. Offline Files caches the files locally for offline use and DFS Replication replicates the data between each branch office. Edited the Does DFS Replication replicate NTFS file permissions, alternate data streams, hard links, and reparse points? If no changes are allowed on the branch servers, then there is nothing to replicate back, simulating a one-way connection and keeping WAN utilization low. I went ahead and did a non-authoritative once more on DC02, and ran a DFSRDIAG SYNCNOW. Lets see just how fast it is Ill create a series of propagation reports for all replicated folders in an RG, let it fan out overnight on all nodes, and then look at it in the morning: Now I have as many propagation reports as I have RFs. This "prestaging" can dramatically reduce the amount of data replicated during the initial replication. For information about pre-seeding and cloning the DFSR database, see DFS Replication Initial Sync in Windows Server 2012 R2: Attack of the Clones. For information about DFS Namespaces, see DFS Namespaces: Frequently Asked Questions. The tool used for migration is a command-line utility called DFSRMig.exe and can be found on a Server 2008's Windows\System32 folder. Hi folks, Ned here again. DFS Replication can replicate numerous folders between servers. Now: I just added the hub and spoke connections here with a pair of commands instead of four, as the PowerShell creates bi-directionally by default instead of one-way only. Yes. Take this into account when the replication group spans multiple time zones. No. This script is intended only for disaster recovery and is provided AS-IS, without warranty. The reasons for this are as follows: Opening .pst files over network connections could lead to data corruption in the .pst files. Disable DFSR Sysvol replication on problematic ADC; Then you should initiate DFSR Sysvol non-authoritative restore on that ADC; Steps to perform a non-authoritative restore of DFSR SYSVOL (like "D2" for FRS) Step 1. To migrate replication from FRS to DFS Replication, see the following documents: To migrate replication of folders other than the SYSVOL folder, see DFS Operations Guide: Migrating from FRS to DFS Replication and FRS2DFSR An FRS to DFSR Migration Utility (https://go.microsoft.com/fwlink/?LinkID=195437).

These are all now implemented directly in the new cmdlet. Its not all AD here, by the way we greatly extended the ease of operations without the need for WMIC.EXE, DFSRDIAG.EXE, etc. DFS Replication replicates NTFS file permissions and alternate data streams. That domain controller has now done a D2 of sysvol replication. DFS Replication supports volumes formatted with the NTFS file system only; the Resilient File System (ReFS) and the FAT file system are not supported. Excessive replication: To prevent excessive replication, DFS Replication uses a system of credits. This is the command line tool for DFSR - useful commands are: dfsrdiag ReplicationState /all - verbose output. The primary member designation is used only during the initial replication process. Hard link files are ignored by DFS Replication and are not replicated. Files with the IO_REPARSE_TAG_DEDUP, IO_REPARSE_TAG_SIS, or IO_REPARSE_TAG_HSM reparse tags are replicated as normal files. DFS Replication opens files in a way that does not block users or applications from opening files in the replication folder. Start the DFSR service on the domain controller that was set as authoritative in Step 2. However, you can export the values using Get-DfsrConnectionSchedule or Get-DfsrGroupSchedule and pipeline them with Out-File or Export-CSV. DFS Replication does not communicate with File Replication Service (FRS). The staging folder location is configured on the Advanced tab of the Properties dialog box for each member of a replication group. Edited the What are the supported limits of DFS Replication? Data replicates according to the schedule you set. Install DFS Management Tools with PowerShell Run PowerShell as administrator and run the following cmdlet. Essentially, the server becomes a rogue primary server, which can cause conflicts. Type Dcdiag /e /test:sysvolcheck /test:advertising >c:\sysvolcheck.txt. Dfsrdiag which is included in Windows Server 2003 doesn't support filehash option. Update managers work independently of one another. Additional Information: To do so, install Services for Network File Systems (NFS) on the DFS Replication server. Added How can I upgrade or replace a DFS Replication member. Examples below: Dashboards However, replicating an entire volume can cause the following problems: If the volume contains a Windows paging file, replication fails and logs DFSR event 4312 in the system event log.
