hi,

i am having a problem on my shared folder ,on Monday i came back to work only to find that some of the folders in my shared areas were missing. so i tried to go check on my back up drive only to find the same thing has happened.

This is so weird,i had recently checked the back ups and they were fine. 

Hello
a brief request for a best practices.
In the case of the problem, we use W2016 std with Workfolders, the Clients are W7 or W10 Prof. with Workfolders and Outlook 2010 or 2016.
Outlook always writes the adxloader.log to the directory structure that is in sync with Workfolders. As a result, there are constant problems with failed synchronization.

My question would be:
Is it possible to maintain an exclude list with the Workfolder so that the adxloader.log is not included? (preferred variant, because also usable for other similar cases)
Or should you routing the path of the adxloader.log? (would be suboptimal for me because it would bend something in the MS Office and might not be update safe.

Who could give me a hint?

Thanks for all.

Danke und liebe Grüße Oliver Richter

Hi ,

     Need help.I have got 1 namespace running on 3 servers.Earlier these were set up to use netbios name for the folder targets .Now we would like them to have FQDN .

Here is what I am exactly trying to achieve:

Only reason to use the script is not have any downtime and namespaces can remain online.

Appreciate the help in advance.

Regards,

We're retiring a 2008r2 file server using NTFS and migrating the files to a Server 2016 server using ReFS.  Using robocopy to pre-seed the files, a small percentage of the files failed to copy.  The robocopy log reported:

ERROR 665 (0x00000299)...The requested operation could not be completed due to a file system limitation

Trying to manually copy the file generated the error:

Error 0x80070299 the requested operation could not be completed due to a file system limitation

The files copy correctly to NTFS volumes, but trying to copy to any ReFS volume on any server generates the error.  If I copied the file to a FAT32 partition (to strip the NTFS metadata), it would then copy to an ReFS volume with no error, but trying to strip the attributes by going to the file properties, Details tab, and using the "Remove properties and Personal Information" option had no effect (it still failed to copy).

I was able to narrow it down to the presence of a particular Alternate Data Stream (ADS).  All the files that failed have an ADS called "AFP_Resource", which is apparently for Mac compatibility (https://msdn.microsoft.com/en-us/library/dn392833.aspx).  If I remove that data stream or clear the contents of it, the file will then copy with no error.

However, we have a lot of files that also have that ADS that do copy successfully.  We have a fair number of Mac users, so I'd prefer not to remove that data stream from all the files that have it.  Ideally I'd like to remove whatever is problematic about the data stream and leave the rest intact.  Alternatively, it would also be helpful if anyone could re-assure me that removing that data stream won't negatively impact our Mac users.  I suspect it's not important, but I'd rather not find out by stripping the stream from thousands of files and end up getting a bunch of phone calls. ;)

I suspect I'm going to end up using robocopy to identify the problematic files and then script removing this ADS just from those files, but if anyone has more info on this I would love to hear it.

More info below for those who might also be struggling with this.  It took me a few hours to track this down, so hopefully this will save someone else some time.

You can see what alternate datastreams exist for a file using either of the following:
dir /w
get-item <filename> -stream * | select Stream,Length

Remove a data stream:
remove-item <filename> -stream <stream name>

Clear contents of a data stream:
clear-content <filename> -stream <stream name>

View contents of a data stream:
get-content <filename> -stream <stream name>

Hello everyone,

I am having a problem here. I changed the domain admin password and now I cannot create or delete folders in  a DFS namespace.

Y restarted the DFS services and still can't add or delete folders.

Best regards

I am getting this error both on a Network Drive AND seeing it on a USB connected drive.

On the Network Drive, the command I am using is....

.... and all works well apart from 3 Folders failing "Access is Denied" on the Time-Stamping process.

These folders are : My Music, My Pictures & My Videos  - yet these folders are "seemingly" NOT in my Documents folder.... clearly some sort of problem due to them being Windows Folders (they are under my User name, without the "My" Prefix). 

Error Message Screenshot to follow (when Account verified by TechNet).

Hi,

I have set read only replication folder ( w2k12) and noticed that lot of backlog so how do we clear this?

As

Hi Support,

I want o assign change permission & I want to remove delete write permission from users on shared folder. 

Example: I have one domain controller and file server. I want to give the change write to users on folder & files.

Not able to create DFS namespace in a completely new forest

OS: Windows server 2016 DFL: 2003 FFL: 2003 DFS role on member server creating very first namespace server - Errors in : The object identifier does not represent a valid object.

Have already tried clearing the container in ADSIedit, Clearing Registry keys:

HKLM\SOFTWARE\Microsoft\DfsHost
HKLM\SYSTEM\CurrentControlSet\Services\DfsDriver\LocalVolumes
HKLM\SOFTWARE\Microsoft\Dfs\Roots\Domain\xxx
HKLM\SYSTEM\CurrentControlSet\serivces\LanmanServer\Shares

and tried re-creating but it fails.

What could be stopping it for namespace creation?? any ideas, two days already spent on this.

and another thing is why do sometimes I keep getting RPC server unavailable?? Windows Firewall is off.

Would really appreciate the suggestions.

I have DFSR replicating folder sbetween 2 servers, at some point the replication was not working so i uninstalled DFSR on the sending member and deleted the DFSRPrivate folder.

Then installed DFSR again, recreated a replication group and added the 2 servers members.

Now if I run a health report  I get the following errors:

The DFS Replication service encountered an unsupported reparse point in replicated folder CA_FILES with local path D:\CA_FILES. This reparse point (DfsrPrivate) will not be replicated because the replication of this type of reparse point is not supported by the DFS Replication service. Event ID: 4406

The receiving member had already a copy of the folder sat some point and I am not sure how in sync it is now?

Should I clean everything again and start from scratch? 

We are copying all our shares to a different drive on Windows Server 2012 R2.

Once this is done, we will be making the drive the same letter of the previous drive. During this process, the old drive letter will be unavailable and this will cause all shares to disconnect and remove all quotas we currently have in place is FSRM.

I have found out how to import all the shares.

Is there a was i can do a backup and restore of fsrm quotas and file screens? (note...this not for the templates)
I was using powershell Get-FSRMQuota, which allows me to view the quotas but not to export them, and if i am able to export them, then how do i import afterwars

none

I am moving from a traditional File Server with Mapped Drives to DFS on a Windows Server 2012 R2. I created 2 namespaces with Folders below the Namespaces. I did move a folder from old server to the folder in the namespace and when I tried to add the folder it gives me an error that "The File Exists".

I moved the folder out of the namespace, still will not let me add 8 hours later. I decided to rename the folder to see if that helped but same error.

Why can I not created folder under namespace even though I moved and renamed the folder?

Hi all,

Had a question I was hoping you might be able to help me with - I've done some research but have come up empty handed. Is there a way to tell what clients are accessing files/folders through DFS. To give a backstory, we are in the process of doing a domain consolidations from a M&A. This company extensively used their DFS name space everywhere (application configuration, drive mappings, printer configurations for scanning, etc). Management does not want to keep the AD environment up serving DFS, since there is no easy way to move the name space to another domain I need to get rid of it in the AD that will be shutting down.

I'd like to have an idea of what devices are using the name space to access files, is there some kind of logging or utility I can use? For example with DNS, I would turn on DNS debug logging to see what devices are sending queries then go address those devices. Would like to do the same with DFS.

Any feedback is appreciated!

I have set up a replication group and folder between two 2012R2 servers.  Replication works fine until I reboot one of them.  Then I get Error 1202  in the Events log with this message:

The DFS Replication service failed to contact domain controller  to access configuration information. Replication is stopped. The service will try again during the next configuration polling cycle, which will occur in 60 minutes. This event can be caused by TCP/IP connectivity, firewall, Active Directory Domain Services, or DNS issues.
 
Additional Information:
Error: 160 (One or more arguments are not correct.)

I cannot tell which argument is not correct. 

I am also puzzled why I was able to set up the replication initially, and it works fine, if the two systems can't talk to the domain controller.

I am not sure there is a shutdown timeout and that I am falling in to the 'Dirty shutdown' scenario because I can't find the events 1006 or 1008 indicating DFS stopping/stopped events.  This is Windows Server 2012, so the hotfix for 2008 to change the DFS recovery should be applied.  And, this is NOT a very active folder so, I expect there is nothing replicating at the time I issue a reboot. 

And, when I try the wmic command to resume replication I get an error.

And, I get these messages after reboot.

So, Why am I able to create the DFSR group, and it works until reboot, then it breaks?  If there is an AD parameter wrong, which is it, and why does it not find that when I create the replication group?

Hello,

we use the deduplication-feature on a machine installed with server 2016 standard. One of the new features of server 2016 ist the multithreading ability. For me this sounds like the process of deduplication speeds up by using multiple cores...

Now we have setup up an test environment to check the performance increase (we use datadeduplication for backups and there are several TiB that need to be deduplicated every day), but there is no significant performance increase. The fsdmhost.exe runs with multiple threads, but in Ressourcemonitor it seems all the threads run on only one core - only one of the 8 core shows workload. The io usage of the diskarray is minimal, under 15%... so it seems, that the io-performance is not the bottleneck.

I've tried to adjust parameters for the job and the volume with no success: Job -Memory 100 -InputOutputThrottleLevel high/low -Cores 100 -Priority High and for the Volume -InputOutputScale from 0 over 10 and 24 to 36

What I'm doing wrong?

Hello everyone.

I have two nodes configuration for Storage Spaces Direct.

The servers were built following the R730xd Dell Matrix Compatibility with S2D with certified components, firmwares and drivers.

Everything goes fine with its configuration until I enabled S2D and checked the Storage Tiers created:It only created Capacity Storage Tier. My current configuration per server (both identical in every component) is:

- Cache: 4 x SSD Dell Enterprise 1.98 TB

- Storage: 8 x HDD Dell Enterprise 8 TB

The cache:storage ratio is 1:2 - the one suggested by Microsoft in this scenario.

Enabling S2D shows in the final validation report that the SSD's are marked as "Disk Used for Cache memory" with an asterisk. Also after creating the pool all the disk are selected and SSD's are marked as Journal, getting all the free space for themselves, and HDD's are marked as Auto-Select with almost all the free space available.

But after this I have checked the Storage Tiers created and only Capacity is showing. No Performance Storage Tier was created for the cache SSD's. I tried creating it manually but no free space is available for this storage tier when trying to create a new virtual disk.

PS C:\Users\xx> get-storagetier -friendlyname capacity, performance | fl *

Hi Guys,

We have a folder replicating via DFS. The replication is set up for over 4000 machines. We had someone delete the entire Replication group. Is it possible to audit or log when any changes are made to the DFS replication group by any user?

Like when someone adds or removes a server from the replication group or when someone deletes the whole replication group.

Cheers,

Edward.

Hello,  We have an existing dfs namespace simply named domain.com\dfs that has 3 replicated folders, Applications, Users, BranchData.  At each branch office there is a local file and print server, and each office is in its on site in AD Sites and Services.  This has been working perfectly for a number of years, but now we have a new office under construction and I am working on getting the new office server ready for deployment.  When I try to add this new server with the new member wizard (simply by right clicking on our domain.com\dfs under Replicaiton in DFS Management, I can get through to finish out but I get an error for each folder:

\\server\Applications.  The folder target \\server\applications cannot be added to the folder.  The file exists.

\\server\Users.  The folder target \\server\users cannot be added to the folder.  The file exists.

\\server\BranchData.  The folder target \\server\BranchData cannot be added to the folder.  The file exists.

I close out of the wizard, and those folders are created and shared properly on the server.  However for local path it shows <not Defined> and has a yellow exclamation point next to it.

Someone on another forum said to try it from another DFS Management console.  I did try from the new server (Server 2016), an existing Server 2012 R2, an existing Server 2008 R2, and also my Windows 10 1803 with the RSAT tools.  All DFS Management consoles produce the same result.  I tried creating the folders and shares on the new server first, and I also tried it with those three folders and shares not on the new server at all... both ways it fails on that error.  This is the first 2016 server in the domain so I wonder if that's part of the difficulty.

Does anyone have a sample passwd file they use for identity mapping?

I placed a passwd file in C:\Windows\System32\Drivers\etc with the following contents:

root:x:0:0:root:/root:/bin/bash

On reboot, Windows did not accept the file, because in the event log under Applications and Services\Microsoft\Windows\ServericsForNFS-Server\IdentityMapping I get a message warning that NFS file access is impaired:

Server for NFS is not configured for either Active Directory Lookup or User Name Mapping.

Without either Active Directory Lookup or User Name Mapping configured for the server, or Unmapped UNIX User Access configured on all shares, Server for NFS cannot grant file access to users.

Configure Server for NFS for either Active Directory Lookup or User Name Mapping using the Nfsadmin command-line tool, or Unmapped UNIX User Access using the Nfsshare command-line tool.
