Can files servers with DFS be used for Profile disks on RDS?

All servers are Server 2012R2

Thanks !!

Hello,

Issue:

On a Virtual Machine with a secondary VHDX attached, I cannot manage (bring online, initialize, partition, format, or write to) the VHDX hard drive once it has "Enable Virtual Hard Disk Sharing (VHD Sharing)" enabled.

Questions:

Should I be able to manage (bring online, initialize, partition, format, and write to) a VHDX hard drive once it has VHD Sharing enabled? If I should be able to manage it, what am I missing?

Topography:

One SuperMicro Cluster In a Box (CIB) with 2012 R2 Data Center on each node. Microsoft Failover Cluster installed and working on each node. The Failover Cluster Servers on each host passes all cluster validation tests. Two Hyper-V 2012 R2 Data Center Virtual Machine (VM) servers, one on each node. 1 common Cluster Shared Volume (CSV) and 1 Generation 2 Scale-Out File Server (SOFS) shared volume both Resilient File System (REFS) formatted. One 5 Gigabit (Gb) Virtual Hard Drive Type X (VHDX) file on the CSV and/or SOFS. Integrity bit and read only turned off on VHDX file.

Each of the two Hyper-V VMs have one 127Gb VHDX Generation 2 primary hard drive and 1 VHDX secondary hard drive attached, both on SCSI Controller #1.

Background:

If I start VM1 without the VHD Sharing enabled on the secondary hard drive, I can bring the drive online, initialize, partition, format, and write to the drive.

If I enable VHD Sharing, I can no longer modify the drive in Disk Management in any way. With or without VM2 running.

Both VMs and the CSV and SOFS are on the same host cluster server, or not, no difference…

The VHDX is referenced either by the CSV name C:\ClusterStorage\Volume1\TEST1.VHDX or a Shared Folder name \\sharedfolder\folder\Test1.VHDX .

If I start VM1 with VHD Sharing disabled and I format the drive, then shut down and enable VHD Sharing, the drive is offline and requests initialization which fails with an "I/O device error", every other attempt to manage the drive fails with the same "I/O device error", error.

Hi,

I have configured a windows server 2012 r2 OS with 2 disks/ The server is a VM. Both disks are SCSI. Hoerver, the data disk does not show in ISCSI setup

Screenshot of the part in question is here:

Any help appreciated

Hi All,

I have setup some shared folders using Access Based Enumeration on  Win 2012 R2 server.
Client computers are Windows 7.

The problem is my users cannot copy from their desktop and paste into the shared folder

i got following error . S:\ refers to a location that is unavailable. It could be on a hard drive on this computer..

Creating/Deleting file from Windows Explorer UNC path working fine, but can't do these think through drive map which is set by GPO.

Out Put of NET USE:

The interesting think is that, when I unchecked   "Enable Access Based Enumeration"
Every thinks work FINE . but many folders listed even the client doesn't have access on them  ... i'd like to use Access based Enumeration  ... 

Thank you in advance 

Hi There,

Hopefully someone can help me with my frustrating issue.

I have users running Windows 8.1 Professional, fully updated.
They connect to the network via Cisco AnyConnect version 3.1 (via Cisco ASA 5510)

File Server is Windows 2012 R2 Standard, it is not DFS, just a single server.

Sometimes the users cannot access the shared folders on the server, they go to access the server via Windows Explorer and it eventually times out with an error message "Remote Procedure Call Failure"

There are 1 or 2 users (me for one) that never has an issue accessing the files (Windows 8.1)

The VPN session seems to be ok, since they can access other services, including an old Windows 2008 R2 File Server, without issues.

None of the users have issues when within the office, only ever remotely via VPN.

I have tried a couple of things to try and get it working, but none seem to work. Disabled all offloadings on the Server NICs, enabled and disabled TCP Auto Tuning..

I have no idea where to go now to fix this issue.

If you need more information then please ask.

Thanks,

-Tim

Hi Guys,

I would like to know how can I integrate File server resource manager with Active directory to set quota by AD users?

Any help is appreciated.

Best regards,

Bahman

I have recently upgraded a clients servers to Windows Server 2012 & since doing so have lost the ability to scan to folder.

Both servers are domain controllers and previously on a 2008 domain controller I would have had to make the following change to allow scan to folder:
 Administrative Tools
 Server Manager
 Features
 Group Policy Manager
 Forest: ...
 Default Domain Policy
Computer configuration
 Policies
 Windows Settings
 Security Settings
 Local Policies
 Security Options
 Microsoft Network Server: Digitally Sign Communications (Always)
 - Define This Policy
 - Disabled

However I have applied this to the Windows 2012 server but am still unable to scan, possibly due to added layers of security in server 2012. The error on the scanner is Authentication with the destination has failed check settings.
I have also tried the following at the server:
Policies -> Security Policies
Change Network Security: LAN Manager authentication level to: Send LM & NTLM - Use NTLMv2 session security if negotiated.
Network security: Minimum session security for NTLM SSP based (including secure RPC) clients and uncheck the require 128 bit.
Network security: Minimum session security for NTLM SSP based (including secure RPC) servers and uncheck the require 128 bit
I have created a user account on the server for the ricoh and set this in the settiings of the Ricoh and verified everything is correct.

Are there any other things I have missed?

I have a problem with a Server 2008R2 running DFS, 3 out of 4 Folders drop out - I just can't figure out what on earth is going on.

It is a Domain based DFS, the namespace is called 'dfs' - e.g. \\domain\dfs, I have 4 Folders called "MyDocs", "Home", "Shared" and "Software" - all of these have a cache duration of 1800 seconds.

"MyDocs" is used with My Documents Folder Redirection, Home, Shared and Software are used with Group Policy Preference based drive mappings.

The problem I have is the Home, Shared and Software Folders simply disappear, thus mapped drives become unavailable. The problem can occur as frequently as every 5 minutes or if I'm lucky, I'll get half an hour of solid reliable DFS usage.

I half suspect I'm not having a problem with the MyDocs Folder because it's linked to Offline files and Windows 7 Offline Files uses background sync.

One thing I will point out, the problem only surfaced after I upgraded my Lenovo laptop to Windows 7 Ultimate x64 SP1, it did not exist when I was running Windows 7 Professional x64 (no SP). Another laptop on the network (Sony VAIO - differnet WLAN NIC), it's still running Windows 7 x64 Professional (no SP), uses the same WLAN and it never has a problem.

I have spent months investigating the potential for this to be a WLAN card (Intel Centrino 6200) and I have noticed other people reporting similar mapped network drive issues on the Lenovo forums (also using these Centrino model WLAN cards).

The problem occurs almost immediately if I try to transfer a large amount of data over the WLAN, e.g. don't bother trying to copy an ISO as will cause the DFS Folders (Home/Software/Shared) to drop-out almost immediately and the copy borkes out. The problem does not occur if I transfer the same ISO over wired LAN ethernet.

I can't get past the fact that this problem didn't occur when running Win 7 Pro with no SP1, I'm not 100% inclined to think this is a hardware or WLAN card issue.

I have screwed around with WLAN drivers, power management settings etc etc etc, jack of that. It's achieved nothing.

I have installed KB983620 but this has had no effect.

A few things I have noticed:

* When the DFS Folders come back online, the Application Experience service on the Windows 7 client has literally just (re)started. As a test, sometimes I'll manually restart it and the Folders will reappear almost immediately after (doesn't work every time).

* Restarting the TCP/IP NetBIOS Helper Service can help force the Folders to come back online (also doesn't work every time)

* Repeatedly browsing the still functional MyDocs DFS Folder (which never drops out) can help prompt the other DFS Folders to reappear (also doesn't work every time)

* I have noticed when the 3 DFS Folders are not available via \\domain.local\dfs\, they will be available via \\domain\dfs and vice versa

* If I run dfsutil /pktinfo - when the 3 Folders are unavailable, the TTL for Home, Shared, Software is sitting at 0 (MyDocs on the other hand is not, it's still counting down). When things are functioning properly, the TTL is counting down for all of them from 1800, when it reaches 0, it starts from 1800 again.

Any ideas?

Hi..

  In my test lab i have created 2 DC with DFS. When i create a NameSpace from 1 server and try to manage the name space from the 2nd server while 1st server is down i cannot Manage it. I also did "Add name server" from 1st server.

Is this normal or am i doing something wrong.

I followed this tutorial:

DFS Step-by-Step Guide for Windows Server 2008 https://technet.microsoft.com/en-us/library/cc732863(v=ws.10).aspx

Thanks and Regards.

Hi All,

I have 2 DFS servers.  They are setup in a primary/secondary situation with users all connecting to the primary server of which the secondary server is a replication partner.  I have plenty of disk space on the primary server but now need to upgrade the disk secondary server.  For this I will need to take down the existing disk array on the secondary replication partner.  Does anyone know how I go about this?  Is it as simple as removing the replication partner, putting in the new disk, seeding and then setting up replication again?

Hi guys, 

I'm a bit baffled by this one. I've got 56 HDDs and 8 SSDs evenly distributed over 3 certified JBODs.I'm trying to set up storage spaced and create a mirrored and tiered virtual disk with four columns. My goal is to get this virtual disk clustered and enclosure aware so I have a failover cluster running. Just to prove my point I'm creating a ridiculously small virtual disk. My script is dumbed down for your reading pleasure. 

Setup:
56 SAS HDDs (1 TB)
8 SAS SSDs (200 GB)
3 Quanta JBODs - certified for storage spaces
2 2012 R2 head nodes with multiple paths to storage
1 failover cluster

So, where exactly am i failing to see the error in this? I've been at it for a couple of days now, and getting tiered :-) 

#Get pollable disks (verify contents manually)
$physdisk = Get-PhysicalDisk –CanPool $true | Where-Object BusType –eq "SAS"
#Get cluster storage subsystem
$stsubsys = Get-StorageSubsystem -FriendlyName "Clustered Storage Spaces on Storagecluster01"

#Create new storage pool and enable enclosure awarenes
$stsubsys | New-StoragePool –FriendlyName "ClusterPool01" –PhysicalDisks $physdisk –ProvisioningTypeDefault Fixed
get-storagepool "ClusterPool01" | set-storagepool -EnclosureAwareDefault $true

#Prepare tiers
$ssd_tier = get-storagepool "ClusterPool01" | New-StorageTier -FriendlyName SSD_Tier -MediaType SSD
$hdd_tier = get-storagepool "ClusterPool01" | New-StorageTier -FriendlyName HDD_Tier -MediaType HDD

#Create tiered enclosure aware disk with appropriate free space for fast rebuild
get-storagepool "ClusterPool01" | New-VirtualDisk –FriendlyName ClusterDisk01 –StorageTiers @($ssd_tier, $hdd_tier) -StorageTierSizes @(20GB, 20GB) -WriteCacheSize 10GB –ResiliencySettingName Mirror -NumberOfColumns 4

Hi folks,

We're about to deploy Storage Spaces in our test environment, but we encountered an issue while configuring Enclosure Awareness on Storage Pools.

When we create a Storage Pool (over 3 JBOD's) and set the option EnclosureAwarenessDefault to $True, the SSD tier size automatically decreases / shrinks to 12GB (sometimes 18GB sometimes 0GB).

Without EnclosureAwarenessDefault, we get 1110 GB of SSD size available.

The same behavior is seen when enabling -EnclosureAwareness on Storage Space (virtual disk) level.

A summary of our configuration:

3 SOFS connected twice to each JBOD (LSI 9207-8e - SES 3 ) = HCL certified
3 JBOD arrays (Quanta M4600H) (Firmware Management SCSI Enclosure Service (SES-2) = HCL certified

Each JBOD array has 16 HDD and 4 SSD.

SOFS are fully patched, including KB 2913766

Below 2 screenshots:

EnclosureAwareDefault = $True

hello

I have one 2012 r2 server with several shares on same partition (d:). Under this shares is 2.000.000-4.000.000 files. Is it number of files/folder relevant for file screening, more files/folders more % cpu usage?

If I enable file screening for example to deny writing mp3 files, how file screening deal with existing mp3 files?

Hi all,

Recently I discovered that our print server is denying connection to some users. 

I found it accidentally when an user with access rights to the printer and server, tried to connect from a non domain computer. 

From the client PC side, the user attempted to connect to \\PRINTSERVER. He wrote domain username and password and all printers were shown, but when he right-clicked on one of them and tried to connect, server asked again for username and password, and got an error that he couldn't connect.

After searching in the DC log event for a failed user/pass attempt, I found lots of events in the print server event view, in the folder

Applications and Services Logs/Microsoft/Windows/SMBServer/Security

Some of them were related to denied anonymous attempts, but others were from client PC trying to connect. The client PC that previously tried to connect gave this event ID 551:

SMB Session Authentication Failure

Client Name: \\CLIENT_PC_IP_ADDRESS_HERE
Client Address: CLIENT_PC_IP_ADDRESS_HERE:58372
User Name:
Session ID: 0xD43C90000049
Status: The attempted logon is invalid. This is either due to a bad username or authentication information. (0xC000006D)

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

Strange thing is that the User Name field is empty. It talks about NTLM and LmCompatibility, but, how do I check LmCompatibility, or whatever is causing a denied access?

Server is a Windows 2012R2 with latest updates hosted in an ESX 5.1, with 2 vmxnet3 nic (as suggested somewhere to avoid compatibility problems between 2012R2 and ESX 5.0/5.1 when using intel virtual nic)

Client PC is an updated Windows 8.1

For testing purposes, I asked another user to test on client PC, and had same result. On client PC, they were logged using a hotmail account (if that matters at all).

On another Windows 8.1 PC using a local account, both users could connect to the server and user shared printer after providing domain credentials.

Anyway, I'd like to remark that I've many errors like this from many client PC, so I believe that it's not just one PC, instead, it's either a problem with the server config, or maybe a bug in  sysprep images.

As CloudThomas suggests in a proposed answer in this technet, I've already changed the way srv2 starts with:

sc config srv2 start=auto

Rest of suggestions are useless as I'm already using vmxnet3  and as you can see on thefltmc output below, I don't have vsepflt driver:

We have a Windows 2008 R2 file server ( running off hyper V)

It has intronis and backup exec installed for backups. 

Users are creating folders on the server and moving files, and sometimes ( not every time but about 20% of the time) the changes they made/ folders they setup will be gone and the files are back in the original directory they were in the day before. 

There are some NTFS errors ( Event ID 55) that say to run a chkdsk, 

which we have done ( chkdsk /r ) 

But we are still having the problem. 

Should we just replace the drive? There is not much on google about this type of problem anyone run into anything like this before?

Thanks for any suggestions. 

Hi,

I have two Windows 2012 R2 servers (both DCs, this is a small org).  I want to replicate several large folders (50GB) between the two servers, which exist on separate sites within the same AD.  I've done a little reading and figure I need to install DFS replication, but do I need it on both servers, or just a single server.  If a user makes a change to a file on either server, is that change then replicated to the other server.  Are shared and NTFS permissions also kept in sync between the replicated folders.

Apols for the basic questions, I really need a 101 session on DFS.

Br,  Ben.

I need to replace a Windows Server backup drive, and another that is used for Client backups.  Both are single drives, not in a storage pool.

I do not need to retain the information on the current drives, I am ok with just backing everything up after replacement.  If it is possible to copy the contents to another drive and put them on the new drive, that would also work, but is not a requirement.

It seems that Windows Server hides the contents of the drives used for backup, which seems to make things harder to manage, but perhaps is best for other reasons.

What is the simplest way to proceed?

Any suggestions appreciated.

Thanks,

Ross
