Hi All,
In my test server, disk goes offline after a server reboot. It came back without any issue, if i select the disk and make it Online.
I want to know the resolution and root cause for the issue.
Server Configurations:
OS: Windows Server 2008 R2
Platform: VMware and Disks are presented from SAN.

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.
We've turned on data deduplication on Server 2012 about two weeks ago. Since then, users are coming across corrupt files that cannot be accessed. At this time I was able to look in Event Viewer at exactly which files were corrupted. About 4 days ago, I found some instructions on "Unoptimization" using powershell command: start-dedupjob -Volume <VolumeLetter> -Type Unoptimization. I waited until after-hours and ran the unoptimization process overnight. When the unoptimization finished, I rebooted the server. I could see the volume size grow but Server Manager still lists the Deduplication Rate at 21% and lists the Deduplication Savings. Today, Monday, users are still reporting corrupt files again.
What do I need to do to get the volume unoptimized? Do I need to completely uninstall the role? Deduplication is disabled. If I attempt to run the optimization command again, it fails immediately. I cannot find any new info in Event Viewer, nothing relating to specifics of the unoptimization or why it fails if I attempt to run it now.
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

Hi at all,
i've a customer File Server (w2012R2 installed on December) with this persistent event, Event Viewer SMBClient Connectivity :
=====================================================
The server name cannot be resolved.
Error: The object was not found.
Server name: "NAME OF OLD DECOMMISSIONING DOMAIN CONTROLLER"
Guidance:
The client cannot resolve the server address in DNS or WINS. This issue often manifests immediately after joining a computer to the domain, when the client's DNS registration may not yet have propagated to all DNS servers. You should also expect this event
at system startup on a DNS server (such as a domain controller) that points to itself for the primary DNS. You should validate the DNS client settings on this computer using IPCONFIG /ALL and NSLOOKUP.
======================================================
The "Server name" reported is a old DC decommissioned mounths ago, i need to understand why and when the server need to resolve this DC.
The Domain have over 40 th DCs and over 500 servers and 3000 clients.
Thank's in advance

Hello ,
Does it work with Hyper-V to create a shared Software Defines Storage (SDS) pool from internal disks on the servers??

Account Manager have Full Control needed.
I already tried a lot from sharing permissions as well as Security>Advanced>Edit special permissions but confused.
How to setup the folder permission? Please help!

I am facing a problem with WMI/DFS. When I am querying DFS shares through wmi, it is not showing all the namespaces and their folder. I am using below query in Powershell as well as wmic
get-wmiobject win32_dfsnode -comutername "dfs1.xyz.com"
WMIC /NODE:"dfs1.xyz.com" /user:"admin" /NameSpace:\\root\cimv2 path Win32_DFSNode
Both the queries showing same results. If I run this query on the same computer, it showing all the details.
Looking for help if anybody came across this issue and had a fix.
Thanks,

We have been burned a few times by high backlogs for whatever reason - DFS has an issue or someone massed changed permissions on a folder and created hundreds of thousands of files needing to replicate.
Long story short though I would like to be notified if there is a high backlog on any DFS server in the domain (we have 5) in any direction for any replicated folder or group.
I found a fantastic script to check this - takes about 40 minutes for the script to run and I can build in alert - ie if count is greater than 1000 - then send an email etc... and then run the script once ever couple of hours.
I assume we are not supposed to link to external web sites but if one was to go to a certain search engine and look for
"How do I get the current DFS replication backlog count? hkey" you would find the powershell script I am referring to. I had to make a change in the comments of the page to make it work for me.
Credit to author Kamal on this. Only change is a time count to see how long script took to run and the changes I mentioned above. Original is just commented out below.
So back to my question - am I over thinking this? - Is there a better event in the event log that I can search for and alert on that will tell me there is a high backlog count - is there an easy way to notify me - hey you might have an issue?
PS - not sure why it thinks the second half is comments... but works pastes into powershell editor and looks fine.

Does we have other options? We cannot pay for NAS.
Thanks in advance.
Following is my network.
I simulate 3 sites on hyper-v server and currently experiencing DFS issue on techen.local domain.
I have configured DFS on CMBDC2012 (DFS namespace and replication installed) and set it as the name space server. I replicate the shares to NYDC2012 (DFS replication is installed).
The changes get replicated just fine.
But the problem is, if a client from NY (NYCPCXP01) access the DFS share when the name space server (CMBDC2012) is not available, it can't access the shares.
If CMBPCXP01 tires to access the shares when CMBDC2012 is not available, same thing happens. It can't access the shares.
I am not sure if this is by design but I want to know if this can be achieved.
Thank you.
Just noticed that user appdata folders are appearing on our 3 DFS file servers. For random users, not all of them. Don't recall ever looking at the User folder on these servers so don't know how long they've actually been there.
My first thought was that a GPO redirection could be causing this but the only ones we applied are for the user documents folders.
Notes:
- These are Windows 2008 servers
- We do not use roaming profiles
- There are no files under the AppData subfolders, just the folders themselves.
Any ideas are appreciated.
Thanks in advance,

Hi There,
Massive shot in the dark here but I am struggling with a pretty major issue atm. We have a production file server that is hosted on the following:
Dell MD 3220i -> iSCSI -> Server 2008 R2 Hyper-v Cluster -> Passthrough Disk -> Server 2012 R2 File Server VM
Essentially 3 times now, roughly a month or so apart. The file server stops accepting connections. During this time, the server is perfectly accessible through rdp or with a simple ping. I can browse the files on the server directly but no-one appears to be able to access the shares over SMB. A reboot of the server fixes the issue.
As per a KB article I removed nod antivirus from the server to rule out a conflicting filter mode driver after the second fault. Sadly yesterday it happened again.
The only relevant errors in the servers log files are:
SMB Server Event ID 551
SMB Session Authentication Failure Client Name: \\192.168.105.79 Client Address: 192.168.105.79:50774 User Name: HHS\H6-08$ Session ID: 0xFFFFFFFFFFFFFFFF Status: Insufficient server resources exist to complete the request. (0xC0000205) Guidance: You should expect this error when attempting to connect to shares using incorrect credentials. This error does not always indicate a problem with authorization, but mainly authentication. It is more common with non-Windows clients. This error can occur when using incorrect usernames and passwords with NTLM, mismatched LmCompatibility settings between client and server, duplicate Kerberos service principal names, incorrect Kerberos ticket-granting service tickets, or Guest accounts without Guest access enabled
and
SMB Server event ID 1020 File system operation has taken longer than expected. Client Name: \\192.168.105.97 Client Address: 192.168.105.97:49571 User Name: HHS\12J.Champion Session ID: 0x2C07B40004A5 Share Name: \\*\Subjects File Name: Command: 5 Duration (in milliseconds): 176784 Warning Threshold (in milliseconds): 120000 Guidance: The underlying file system has taken too long to respond to an operation. This typically indicates a problem with the storage and not SMB.
I have checked the underlying disk/iscsi/network hyper-v cluster for any other errors or issues, but as far as I can tell everything is fine.
Is it possible that something else is left over from the NOD antivirus installation?
Looking for suggestions on how to troubleshoot this further.
Thanks
How we can monitor if there is any drive failure or storage pool or virtual disk or volume getting full ?
We use splunk to monitor servers so it can check for these events below on two cluster nodes and email us. Any thing else I should look for ?

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,
I would like to create a failover clustering without SAN on Windows 2012.
I have 2 servers with 4 hardrives but 2 HDD (share file drive) in Raid1 on each.
I want to create an IP virtual for the hardrives in Raid1 to input the IP on Failover clustering service.
Is it possible ?
Thanks for your answers.

First, I apologize if I did not include enough details, I am not sure what to include.
I am looking into an issue at my friend's business. He has a Windows Server 2008 R2. Some Windows updates occurred at 3 AM and
ever since then, "Target account name is incorrect" error message comes up when attempting to access a network drive via all the computers. Can't find the network mapping component in the Group Policy Management area to map the drive out through
a group policy.
The drive in question was mapped out into each computer individually through "Map Network Drive" previously. Removed it and tried to re-add it on one of the computers, the same error occurs when attempting to add it through "Map Network Drive". The computers its occurring in have Windows XP, 7 and 10.
The Driver in question shows up under Share & Storage Management. Shows also that everyone has permission.
I then tried to add it via Group Policy Management and did gpupdate /force. First, I got "Error (0x80070070) occurred saving settings file. There is not enough space on the disk". I ensured that the quota management is disabled. When attempting to gpupdate /force , I got this error "the processing of group policy failed. Windows could not authenticate to the active directory service on a domain controller".
I hope someone can help me look into it. Thank you so much. My apologies if I missed out any details, not sure what else needs to be included.
