Hi guys, I have a question. I'm looking for what a best practice would be (best performance / best practice / best support)

I have 2 sites which are connected via VPN.

I would like to set up a DFS between both sites but the two sites have 2 different domains. 

My question is what would be the best way to set up a DFS. 

Should I 

A) Just join machine on site B to site A domain and create the DFS

B) Do a cross domain DFS which would require a two way domain trust I assume

C) Any other option I might not be thinking of

**Site A would be the master site and site B would be the replication in the event site A dies site B DFS would take over**

Thanks! :)

Hi,

When deploying Windows Server 2016 work folders how can we deploy client settings via group policies if the domain controller is Windows Server 2003 R2. It has settings only for Offline Folders.

Regards,

Hi,

I have some servers running 2012 R2 with active Work Folders feature. They will be replaced by 2016 machines. Is there some howto regarding the migration of Work Folders feature?

The sync shares are created with file access only for the users itself. Work folders URL is distributed by GPO to the clients and setup is enforced. Clients are Windows 10 1709 and 1803. 

Before Windows 10 1803 the clients had all the data and changing the sync share was easy. Clients were just resynchronizing their files to the new, empty share. Now with the new features, most files stay on the sync share server and only a few files are offline available. 

So how do I handle this? 

Thanks, Ingo

Hello,

I have researched online but could not find anything relevant. A hyper-v managed windows server 2016 instance is crashing and throws multiple events of:

"The IO operation at logical block address 0x###### for Disk 0 "

 On the hyper-v host, after the VM has crashed there has been a pattern of a SMBClient 30611 error of:

"

Failed to reconnect a persistent handle.

Error: The account is not authorized to login from this station.

FileId: 0x200000E0265CBEE:0x20E000000A9
CreateGUID: {b3d6066e-563c-11e8-a949-0002c937dda1}
Path: \networked\path\to\instance.vhdx

Reason: 201

Previous reconnect error: STATUS_SUCCESS
Previous reconnect reason: The reason is not specified

Guidance:
A persistent handle allows transparent failover on Windows File Server clusters. This event has many causes and does not always indicate an issue with SMB. Review online documentation for troubleshooting information.

"

Followed by several 30906 errors:

"

"

Then the server crashed. If someone has any ideas or could point me in a direction to recover other more logs that would be super.

Thanks!

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?

Hi all,

I use Windows Server version 1803.

I create nested S2D PoC on Windows Server 2016 Hyper-V.

I can not "Enable-ClusterStorageSpacesDirect–CimSession <ClusterName>"

Does anyone encounter the same error?

I was copying files over from one server to another from my client computer. I was wondering if it would be better (in terms of performance) to do it from one of the servers instead of from my client. 

So to clarify, I am on computer A opening network share from computer B & C and moving files from B to C via the interface of A. Would it be better for instance if I log on to the desktop of computer C, then open the network share to B and move files like this? 

I hope it's a bit clear my question :-)

This problem really annoys me - and it seems like either a Windows bug or poor design.

Hopefully it's neither and it's just me :)

I have reproduced it in Windows Server 2016/2019 Datacenter

1) Create a Virtual Machine, install Windows Server Datacenter

2) Add multiple drives to the VM

3) Add multiple drives to a Storage Pool (make sure that you set MediaType to both HDD and SSD)

4) Try to create a Virtual Disk through the GUI (actually it fails in Powershell aswell). Make sure you set the Size to Maximum size.

This will fail and you will get an error saying you don't have enough resources but in fact you can just choose a lower size and it will work just fine. I tried to play around with the sizes and I think that the only problem here is that the "Maximum size" is calculated wrong thus given an error.

We have a file cluster (FILECL1) in datacenter A, and a file cluster (FILECL2) in datacenter B.

FILECL1 is the active file cluster and, using Storace Replica, the data disk is replicated to FILECL2 for disaster failover.

So, in failover cluster manager (on FILECL1), I've added a role of type 'File Server', it has the name 'FILECLUSTER' and has some shares on it.

People can browse to \\FILECLUSTER and use the shares. If one node goes down of the FILECL1 cluster, no problems..

Storage is replicated to FILECL2 using Storage Replica (cluster to cluster). But how do you document/configure the disaster failover part?

I tried DFS, to create a DFS name that would span both clusters, but I couldn't get it to work. If FILECL1 goes down, the whole cluster, I need to change the direction of Storage Replica with a Powershell command, so that FILECL2 becomes the source and is readable, but, \\FILECLUSTER will still point to the FILECL1 cluster that's down .. I don't find any specific information, only that storage replica is awesome etc.. :) So what's the best way to make sure that users and applications don't need to navigate to another share name?

Would someone please provide detailed instructions, or a link to instructions, on how to create more than one Pool in S2D?

I have seen many requests, and responses, that it can be done, but no direction on how.

Thanks,

Todd

Hello,

I have 3 volumes of 4TB each.  Each of them have a scheduled dedup job that runs at 6am.  When the schedule job starts at 6am they all run simultaneously.  But if I have to run a manual dedup job on a newly created 4th volume while the initial 3 volumes are in process of deduping,  the  job of the 4th volume goes into the queued mode.  It stays in queue until any of the previous volumes have been completed.  Now if i add the newly created 4th volume as a schedule dedupjob then all 4 volumes run at the same time without issues. Does any one know how to force start a dedup job without it being queued?

Thank you.

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

Hello everyone!

I am renaming the windows 2012 server which has AD,IIS7 and MS SQL server 2012. There are several shared folders which user access over the network. How can I change the UNC path //oldserver/user1 to //newserver/user1 over a script .I dont want to delete the folder and create anew one as there are close to 1000 shared  folders. Please help me through this ? 

Hey,

We have a very random issue where Offline Files sometimes flags up 'Access denied' and users can only see the local cache copy of network drives.

After a few reboots it just seems to fix itself. We actually set slow-link mode too and this made me think it was some of the issue, but the offline files operational log doesn't not show anything untoward.

For a user that had 'access denied' yesterday, but is totally fine today:

The DNS domain name is: domain.consto.com

The Pre-windows name is: netname

\\domain.consto.com\sysvol works fine. \\domain\sysvol does not work. It keeps asking for credentials to access it with an access is denied.  No matter what you try, it doesn't work.  "netname\administrator" does not work.

I dfs-share on the domain controllers works file with \\domain\{dfs-share}.  So why does this work and "netlogon" and "sysvol" not work?

There is nothing in the security log.

Also server 2016 is now the domain controllers and the 2008 servers were removed.

Any ideas why this happens?

Greetings,

I have an old roaming profile that I need to delete.  However any time i try to delete it is says "you require permission from "my own user" to make changes to this folder.

Anyone know a solution? I can take ownership but it gives me the same error.

Thanks,
