Hello,
My DFS seems to be running correctly on the 3 servers. However, on some of the larger folders (100GB+), there are a very large number of files in the deleted/conflicted folder in the DFSPrivate folder.
Should this be concerning? Can I simply go in there and clear out that folder without harming anything?
Objective:
On a Windows 2012 R2 server, enable Deduplication on a new 20 TB D: physical volume. This volume will become a target for Veeam Backup and Replication backups.
Problem:
Deduplication fails to dedupliate anything. Get-DedupStatus always reports 0 B SavedSpace and 0 OptimizedFiles.

I uninstalled the Deduplication role, rebooted, and reinstalled the Deduplication role. Before applying Deduplication to a newly created volume, I populated that volume with about 2 GB of data. I then used the ddpeval.exe tool to determine the results that I should achieve if Deduplication was enabled on this volume.

I don't have any problems or errors installing or running Deduplication. I simply have no results. More importantly, my Deduplication results do not match the Data Deduplication Savings Evaluation Tool's predictions. How should I further troubleshoot? Thank you for your time.
Hey everyone,
I have not been able to find a definitive answer for this question and was hoping that someone could answer this. Is there a problem with replicating DFS Namespace root folders, rather then creating the shared folders under the namespace root?
For instance we have two servers with two additional large drives each. We would like to have each drive hold it's own DFS namespace, then replicate it to the other server. For instance, both server A and B would have D:\Public folder that would be \\network\Public name space. And both server A and B would have E:\Home folder that would be \\network\Home name space. Then just create a replication group for \\network\Public and another for \\network\Home.
Thanks in advance.
Hi,
II'd like to know if there is any truly working solution for establishing an anonymously accessible file share on Windows 2008 R2 (SP1) server running Active Directory (domain controller) and File Services.
I've been crunching through all google hits on that issue and seems nobody has gotten it to work unless the Guest Account was enabled (not an option for production domain controllers).
So far I tried all this to no avail, server keeps prompting me for username/password when I try to access such share from non-domain Windows computer:
1) created a folder, e.g. ASHARE and shared it under the name ASHARE$ ($ so it stays hidden from public)
2) assigned both share and ntfs permissions allowing full access to EVERYONE, GUESTS and ANONYMOUS LOGON
3) edit Default Domain Controller GPO to make following changes (under Local Policies Security Options and User Rights Assignment):
-enabled policy "Network access: Shares that can be accessed anonymously" and put "ashare$" on the list
-enabled policy "Network access: Let Everyone permissions apply to anonymous users"
-disabled policy "Network access: Restrict anonymous access to Named Pipes and Shares"
-changed policy "Access this computer from network" and added ANONYMOUS LOGON account to the list
-made sure the policy "Deny access to this computer from network" does NOT include any of: Everyone, Guests and Anonymous Logon accounts
-checked policy "Do not allow anonymous enumeration of SAM accounts" and this is disabled by default, but it doesn't have impact on Domain Controllers anyways.
-checked policy "Do not allow anonymous enumeration of SAM accounts and shares" and it is currently disabled (and should be unless I am reading it backwards?)
what else left?
The server still keeps prompting me for password when I try accessing \\server\ashare$ from any non-domain computer/user account. why is that so, what am I missing here? it should be a simple thing! I just need public dropbox folder on this File Server...
Good morning all -- have a question about extending a volume on Server 2008 R2.
The volume is an iSCSI target using the Microsoft iSCSI initiator -- the iSCSI device is a Dell MD3000i.
The volume was originally 500GB. On the MD3000i, I expanded the space from 500GB to 1TB -- this went fine without any issues. Once the space was expanded on the MD3000, I hopped on the server and saw the available unallocated space on that drive.. So, I followed the normal MS guide to extend a partition using the unallocated space -- I used the command prompt, diskpart, method instead of Disk Management GUI.
After extending the disk (which went fine without any issues), I can now see Disk Management reports the drive as 1100GB instead of the original 500GB. However, when I go to My Computer, it still only shows the disk as being 500GB. When I right clicked on the volume to check the properties, it still showed 500GB but it didn't look right -- I recall some a couple of the areas just showed 0 bytes even though the disk was working and was usable.
After rebooting the computer, the problem still persists -- I did run a 'chkdsk /R G:' so it could find/repair any errors -- this fixed the 0 byte errors I saw on the drive properties.
It should also be noted that from the MD3000, it is showing the volume as a 1100GB target instead of the original 500GB (so that looks fine).
Any reason why this additional space is not available for use?
I notice that whenever my java program is moving files to a folder, there is no owner assigned to that file. How is that possible? Now I am not able to move that file to some other folder except delete.
Any way to assign ownership to the file before moving the file itself.
Thanks in advance.

Hi,
I have a 2012R2 Std server with 3 x Dedup volumes and one of them has reverted back to a Dedup setting of Disabled, twice now. This also clears all of the excluded folders in the dedup exclusion list.
Any ideas why this could be happening?
Hello all,
I’ve configured MPIO on a Win2k8 R2 and added several Clariion volumes in it.
To install Clariion DSM, I installed EMC PowerPath 5.7.1 SP1 software. Added "DGC RAID 5" and "DGC RAID 10" in "MPIO->Discover MultiPaths" tab. Then claimed the disks viampclaim.exe -r -i -a "" command.
I’m not able to make the Clariion Volumes to be claimed by MPIO. (MPIO’ed for Clariion volumes is False):
C:\Users\Administrator>mpclaim -s -d

Here if you notice, “System Disk” is N\A for Clariion volumes and “MPIO’ed” is No.
To solve this issue, I disabled PowerPath services and claimed (mpclaim.exe -r -i -a "") again and rebooted machine. But the output remains same.
Any help or suggestions to resolve this issue are welcome…
Thank in advance

Hi Support Team,
We have File server that using share folder over network. I have to audit the files and folders.
I have configure the Group Policy settings like Local Settings - Audit Object Access - Select Success and Failure.
Then i have configure auditing on Root Share folder. and in sub folder i assign the permission with block inheritance and added the users to full right. ( Administrator Account Also).
After doing all this step i am not able to access the folder which i have given the full permission. even the administrator have only read only access.
can you please help me on that. how to do that.
Thanks,

Hi,
I've got a domain setup with four DFS namespaces setup to allow easy access to the files. However something has happened which has stopped the namespaces from working.
I've deleted the entries from ADSIEdit on all but one machine, I can't do it on there because it isn't a domain controller. I have however deleted the DFS Namespace entry in the registry and rebooted all servers.
And if I try to recreate the DFS Namespace from any of the servers I get a error message saying "The namespace server \\SERVER\Share$ cannot be added. The specified domain either does not exist or could not be contacted" - Despite the domain being active and all servers and computers are able to access other resources and each other.
Thanks!
I am wanting to replace a 2003 (not R2) File Server with a 2012R2 file server and preferably keep the same machine name and IP when finished. For the moment I just need some "high level" guidance, little details can be worked out once I know which direction I will go. I was considering that DFS might be a way to help get through the process although when finished the 2012R2 Files server will be by itself with no other file server planned at this time. DFS can stay installed for maybe future purposes but clearly I wouldn't need the DFS Replication with only one machine.
Here's a few details of the environment....
1. DC's are 2012R2 but it is still 2003 DFL because the old 2003 DCs are still present. But likely they will be gone and the DFL elevated before I start on the File Server project
2. Nearly all machines in the facility have a shortcut on the "All Users" Desktop that points to the existing old File Server. Editing or replacing that shortcut would be a major pain,...hence why I want to keep the same machine name at least,
and maybe the same IP if not too much trouble. This way the existing shortcut would continue to work with the new 2012R2 File Server. The UNC path represented in that shortcut is also configured into one or more of our major business applications,
futher emphasizing the need to keep the UNC path the same throughout the process.
3. The facility runs 24/7/365 but is "light" on weekends. The political environment is such that there is little to no tolerance for any down time at all.
4. Would DFS (based from the 2012R2 machine) be a good tool to get where I need to go?
Thanks for any suggestions.

Dear All
i have to create a sharefolder on the network
i have a domain controller with AD
and a file server
so i create a folder , share it on my fileserver
then in AD i create a sharefolder and gave the path that i created in my fileserver.
but i would like to manage the access to that sharefolder from my AD
on the properties on the sharefolder in AD i only have general and managed by
i can set the user who can manage it but i tried to set a user who can manage the folder.
i would like to let all the users of my OU to access that sharefolder cause i have created that sharefolder in the specific OU.
when i log with a user that does no belong to the OU where i create the sharefolder he can access the sharefolder
normally i should have a security tab in the properties of that sharefolder to manage the permission i dont have it
can someone explain please?
thanks
Two 2008 R2 servers. Been running DFS-R for about a year now. Generally no problems.
If I run the DFSRdiag backlog command on either server, for one particular folder, it says there is no backlog. The only problem with that is; on one server there are 11 files in that folder, on the other server, in the same folder, there are 15 files. How is this even possible!
Hi All,
I am running an W2012R2 Essentials VM as AD and file server. And I want to add/change certain quota templates. This should be done via the FSRM role in MMC. The FSRM role/feature is installed and running. However, there is no entry labeled "File Storage Resource Manager" under Server Manager/Tools. Neither is there a FSRM addon that can be loaded into MMC. What am I doing wrong?
Any help greatly appreciated.
