I have two file server both 2012r2.  I installed the DFS Namespaces and DFS replication roles on both servers.  I then created a simple namespace called ITDFS and added a folder to the namespace called IT Test1.  I added the second server from the DFS managment console and added a folder by the same name to it.  I then added a replication group via the wizard.  I was able to add text and excel file and have them replicate between the two servers.

About an hour later I received a call that folders (on the server that I initially configured DFS on) were missing.  After using a utility called tree size I was able to see that several hundred gigs of software was moved into the DFSR/Private/PreExisting folder.

1.  At no point did I ever configure this set of folders to be included in DFS replication.  It was several folders deep so there is no chance I accidentally navigated to it during my DFS testing.  Also, I would have never selected some 200 folders at a size of 347 GB for a simple DFS test.  I have no idea why these files would have been moved to the preexisting folder, which I understand is readying the files for replication.

2.  I cannot get into the DFSR private folder for the life of me.  I have forced the permissions on it numerous times to no avail.

Any idea why my files would have been moved and how do I get them back?

Hello All,

I configured DFS namespace and give the physical path direct to D:\Public folder. This folder contains users data on server DFS01. Next I added another namespace server called DFS02 and folder path similar like D:\Public folder.

Next I create a replication group, and add both the server and same D:\Public folder path. It replicate successfully from DFS01 to DFS02.

This is a single office (single site) and when a user trying to access \\domain.com\Share folder, most of the time DFS02 folder path open and randomly sometime DFS01 folder path.

User's complain when they open their folder, the file is missing they just created. 

I configured in namespace DFS override referral ordering and select DFS01 as First among all targets. But this is not working !!

Thanks

Hello, 

How do I get information from a local windows account to a domain account? If possible.

Thanks! 

Hi, I am testing work folders at the moment and having an issue with one client machine. When I try to add the folder using the wizard I get to the last step and when I click Set up work folders I get:

There was a problem setting up Work Folders

Please Try again.

An Unexpected error occurred. (0x86000005)

This machine was able to complete once but not after that. I have tried on another client machine with the same user account and it worked. I have also tried a different user account on the affected machine and that gave the same error. BOth machines were running Windows 10

Any help appreciated.

Thanks

Added SERVER3 as the third member of an existing DFSR replication group. The other two members are SERVER1 and SERVER2. While adding SERVER3, I indicated that I only wanted it to replicate with SERVER2, and the initial synchronization started. There is a backlog from sending member SERVER2 to receiving member SERVER3 that started at over 600,000 three days ago, and has since then decreased to just under 300,000. As that backlog continues to decrease, a backlog is growing in the opposite direction (smem SERVER3, rmem SERVER2).  It stands at just over 17,000 and continues to grow slowly.

it seems strange that there would be any backlog at all from SERVER3 to SERVER2, considering there was no pre-existing data.

Items at the top of the 17,000 count backlog aren't changing, and this seems to correspond with an error I'm seeing in the debug log:

[Error:9051(0x235b) OutConnection::TransportEstablishSession outconnection.cpp:449 7512 C The content set is not ready]

My interpretation of this is that SERVER3 is waiting for the initial synch to complete before sending anything back to SERVER2.

Any ideas?

Anyone else experimenting with Storage Spaces and find that the Tier should be where Resiliency Setting are defined?

It would make sense to have Tier's will various resiliency settings.
(Write-Intensive SSD) - Raid 1/10
(Write-Intensive SSD) - Raid 5/6/50/60
(Read-SSD) - Raid 1/10
(Read-SSD) - Raid 5/6/50/60
(7k HHD) - Raid 1/10
(7k HHD) - Raid 5/6/50/60

Command might look like this:
New-StorageTier -StoragePoolFriendlyName "Archive Storage Pool" -FriendlyName "(Write-Intensive SSD) - Raid 5/6/50/60" -MediaType SSD -ResiliencySettingName Parity -PhysicalDiskRedundancy 2

Maybe one would need to include what disks in the pool to use for this Tier also similar to adding disks to the StoragePool but it would require them to be a subset of the disks already in the pool.

Then you could mix multiple Tiers with a Virtual disk to achieve various performance requirements or storage reliability/capacity/usage requirements.  If data is not used it could move through various Tiers to ultimately land on the slower capacity based Tier.

If you fill Tier 1 space then data could be written to HHDs with Raid 1/10 and still get better performance than standard HHD with Raid 5 or Raid 6 and then later as data is progressed it can be moved to Raid 5/6/50/60.

I heard that Parity is not supported with Tiering also but when I tried it via the command line there was no objection to the configuration so perhaps that either old data floating around or its just the GUI that does not offer Parity with Tiering?

Just some thoughts.

Windows 7 workstation, Windows Server 2012

Issue:

Workstation A updates a file and saves the file on Server in a shared folder, Workstation B access the file from the server and doesn't see the updates that Workstation A made. This is intermittent. Other workstations on the network do not have this issue.

Testing:

1) Verified both workstations and user logins are pointing to the same location.

   a) Created a file in shared location from each workstation and each workstation can see the new file and access the file

2) Workstation A copies the file to desktop and deletes the file from the server and workstation B can't see the file.

       Workstation A then tries to copy the file back to the location and gets a message asking if they want to overwrite existing file. Workstation A searches the shared folder an cannot find the file. Workstation B now sees the file that Workstation A deleted. However Workstation A cannot find the file. 

Any help or direction to look at would be appreciated.

Was interested to see if I could use Work Folders instead of DFS-R to sync folders between 3 locations.

Site A Datacenter would have Folder Site B and folder Site C

Site B would have Folder Site B which replicates with Site A

Site C would have a folder Site C which replicates with Site A

Users connecting to Site A would access files only from site A using namespace

Users in site B would access site B folder locally and site C folder from Site A both via the namespace path.

Users in site C would access site C folder locally and site B folder from Site A both via the namespace path.

I am curious if there would be issues with file locking as we have with DFS-R which is no file locking options.  Not to mention if a file change is saved and the information is sent to the Jet Database to sync and someone modifies the file it can create propblems requiring IT to get involved.

Hi,

We have  customer servers which has DFSR configured. There are two folders D:\Home and D:\Users which are under DFS replication. We were seeing the event id 4502 daily for the above folders. We did change staging folder path to different location (off Home and Users folder). The new path is D:\DFS\Home\Dfsrprivate\Staging and D:\DFS\Users\Dfsrprivate\Staging. We did set staging quota size to 50 and 150 GB respectively. After this change, we don't see this event id 4502 for D:\Home folder. However this continues for D:\Users folder. DFSR diagnostic reports shows the same. It points to d:\Users folder.

In these servers, FSRM is configured and hard disk quota is set to 1 GB on both D:\Home\* and D:\Users\*. Since we have changed the staging folder path from default location(off D:\Home and D:\Users), we thought it would resolve the issue. But no luck for D:\Users. As per the below link, I tried to run the command lines to get first 32 largest file size, but it fails with Access is denied. Not sure how to get the information. Please help me to resolve this issue. Let me know what information is required.

I had an OLD FileServer, WIN2012R2, 3 TB Volume with Dedup enabled and average rate of dedup it was 49%-52% over tha last 3 years. IN 2016, the free space of the volume is going down and in january we had 10% freespace and yesterday it was less than 1% of free space on the old file server last week

We bought  a new FileServer, Win2012R2, 10TB volume and i´ve migrated all 5.5 MILLION of files this week

Now the dedups saving rates is 72%!!!!!!!!

If the files are the same in both volumes, how could the saving rate grown up so much?

Maybe because there is more disk space avalable? 

What i was expecting is the same saving rate for both servers, because the set of files and folders were the same. But after a week preparing the migration, copying files 2 weeks ago in full mode and in the last 5 days doing incremental copies, why does the saving rate is so higher than earlier?

Hello All,

Which DFS replication is a best solution to manage, to take backup, for redundancy with namespace and multiple folder targets.

1> Replicate a single root folder (with all department folders and files) having 1 TB of data to another server? Single replication group and multiple namespace folder targets

2. Replicate multiple folder by providing multiple folder target and replication. In this way, there will be multiple replication groups.

I face issues earlier, with single root folder replication, after the replication completed, all users start complain, the files are opening read only... I did not added second server into namespace that time.

Any advise?

Thanks

Hello, 

I was wondering if I can have a 6TB HDD on my server and each domain user have like 500GB each and a folder that only they can use. 

Thanks!

We recently setup Workfolders and it works fine internally but we get the error "The server's SSL certificate contains incorrect hostnames." error 0x80c80338 when trying to sync from outside the LAN.  I saw other posts where this error occurred because the SAN hostnames in the Cert were not correct, but we are using a wild card certificate so the certificate doesn't have any hostnames in it.  I don't understand.

The sync share "Workfolders" is hosted on server that we'll refer to as server.internaldomain.com. The hostname Workfolders.externaldomain.com is registered in both internal DNS and external DNS.  I confirmed that both the DiscoveryURL and the ServerURL in the ...\WorkFolders\Partnership\Microsoft.SyncShare.UserData section of the registry are set to https://workfolders.externaldomain.com/sync/1.0.  A wild card certificate *.externaldomain.com is bound to the server and confirmed with a query "netsh http show sslcert".

Internally, discovery and sync works fine without any errors.  However, sync fails on the outside with the error  "The server's SSL certificate contains incorrect hostnames." error # 0x80c80338.  The registry entries confirm that the client is syncing to Workfolders.externaldomain.com and the wildcard cert is there for the externaldomain.com.  Why would I get that error?  There is no hostname in the certificate and the domain names match. The certificate is a valid GoDaddy cert and it has not expired.

Does anyone have a clue as to what is going on here?

I can't seem to find a good solution to this issue (maybe there isn't one). I'm simply trying to share an external drive directly from a Windows server across the network.

I'm running Windows Server 2008, and have a RDX USB external drive which I would like to share. The share sets up fine, all workstations can see it.  However, after what seems like a random amount of time, and maybe 2 or 3 cartridge swaps, the workstations can no longer access the drive, even though no permissions changed and the share still exists.  If I actually make another share, it will work (for a while), but the original share will still not work. 

Neither the workstations nor the server itself can access the drive via the "Network" icon, but the server can still access the drive through the "Computer" icon of course.  The error I'm getting is that Windows cannot access the shared folder, with the error code 0x80004005

Is this something that simply can't be done on a Windows server?

Hi experts,

  We run our SAP on SQL Server with Windows Server Failover Cluster and I migrated one DC(qrdcsapdc2) to another DC(qrcsapdc7) a couple weeks ago. I found there are many error 22 for write/read access to a file on AD Shared Folder from 9/8 2:00am ~ 4:00am

The first weird part is the timeframe is very regular. Its occurred only from 2:00am ~ 4:00am(9/6 2:30am happened, too)

1. The second weird part is we have 7 Additional Application Servers(tccap51 ~ tccap57) and it occurred only on 3 AASs(tccap53, tccap54, tccap55)
2. By the way, I have disable 8dot3name(fsutil 8dot3name set S: 1) according to SAP note 662452 on 9/6 but I have not restarted OS yet.

File = \\tccprd1\sapmnt\TCP\SYS\global\218JOBLG\0001X01450800X50446

Cannot close the file of a TemSe object (error no 22)

Possible causes & solutions?

1. Something wrong on Active Directory(DC) authentication issues and I prepare to restart all DCs, DBs and AASs to get new authentication tickets.
2. Intermittent network packet loss?
   • Replace with new network cables and switch ports
3. Others….

Please help. Any comments are appreciated.

I am in the process of migrating data from a file server in a domain to another file server in a different domain. I will be using Robocopy to migrate the data and then exporting the shares manually from the file server registry. 

I am researching a tool that can backup both the share and NTFS permissions on the root folder (and subdirectories) in the source domain and restore them in the target domain.  I have not looked into SUBINACL yet as I know it is not supported on server versions after windows 2003. I would prefer Powershell but have run into issues with long filenames during the testing phase. My powershell script looks like this:

Get-Childitem -path G:\Dept -recurse | Where-Object {$_.PSIsContainer} | Get-ACL| Select-Object Path -ExpandProperty Access | Export-CSV c:\scripts\tony\acl-dept-ntfs.csv

Hello:

Our company recently purchased an Epson BrightLink Pro interactive whiteboard. The system has the ability to save files created in whiteboarding sessions onto a network share.

I've added the UNC path to the settings page for this device, along with an AD account and password. I still cannot connect to our file server. I know that the user account, called "scanneraccount" isn't locked out. I've verified that the password is correct. I can login to a workstation using these credentials and it logs in OK. I've tried using a machine name and IP in the path and neither works.

I know this isn't an Epson forum, however I was wondering if someone could give me information on what to look for in the event viewer on our file server to see if the device is even reaching our file server. I'd like to find clues to see if an incorrect username, password or UNC path error is shown.

I know all events aren't audited by default, so if I need to have my sysadmin turn any of that on, I'd need to know what specifically.

Thank you for any help you can provide.

I'm getting these alerts from our monitoring and have it tracked down to why it's showing the users share in DFS as uninitialized, even though it's state is actually normal.  The replication group has been added and removed over and over and renamed.

Right now I have these replication groups:

Admin

Domain System Volume

Shares

Users

And there are no issues.  But monitoring uses WMI and as such the following command shows the real issue:

Wmic /namespace:\\root\microsoftdfs path dfsrreplicatedfolderinfo get replicationgroupname,replicatedfoldername,state

ReplicatedFolderName  ReplicationGroupName              State
Admin                 Admin                             4
Shares                Shares                            4
Users                 pipt.local\dfsroot\users    0
Users                 pipt.local\dfsroot\users    0
SYSVOL Share          Domain System Volume              4
Users                 pipt.local\dfsroot\users    0
Admin                 pipt.local\dfsroot\admin    0
Users                 Users                             4
Users                 pipt.local\dfsroot\users    0
Users                 pipt.local\dfsroot\users    0

Line items with a State of 4 are correct.  They are also the ones that match the naming convention in the console.  Admin and Shares were removed and renamed once it looks like.  Users over and over again.  But it is these references that the monitoring software is querying, so it appears.

How do I rectify this?

It looks like i need to delete all of the  pipt.local\dfsroot\users  replicationgroupnames, and the one pipt.local\dfsroot\admin

How do i do that safely?

Thanks in advance.
