HELP! DFS Shares suddenly unavailable after lateset updates - no errors

September 30, 2015, 9:03 am

Good morning,

This morning all of our office experienced slow logons and missing drives that should have been mapped to DFS shares.
No errors in any event logs on the servers, just the client, indicating that the server is unavailable. The DFS shares are accessible if I just go to run, and type in the same path name to the DFS share.
We have two targets at this site, an older server 2008R2 file server, and a newer 2012R2 files server introduced 3 weeks ago. We've been running this setup for 10 years with no problems, starting with 2003 R2.

I ran a batch of updates to the 2008R2 files server last night. None of the looked to be related to DFS.

I've tried retargeting to the 2008R2 DFS share by making the 2012 R2 one the last in the manually defined order, but there has been no difference. There doesn't appear to be any DNS issues between servers.

If I run a "net use h: /home" it takes a long time, then returns "Drive h: is now connected to \\mydomain\department. Your home directory is h:\it\Brad".
When I type h: it takes me to the DFS root, not to my home directory. We have another drive "I" which is a common DFS share that maps fine.

4 days ago I did remove DFS, DC, DNS services from another aging 2008R2 server with no problems at the time.

I can't tell what is broken without an error message. Where do I look?

Thx

Same error on various Windows Platforms - 7 & 8.1 - Cant Add, Edit or Delete on Shared Network Drive

September 30, 2015, 5:01 am

I thought it would be best to put my issue here as i get the same issue on Windows 7 & 8.1

This issue first came about when one of our new staff told me they kept getting 'you need permission to perform this action' when creating a new folder or editing existing files on a shared network drive.

Now i am a domain administrator and being a shared network drive i have double and tripled checked that she has access as her permissions on this drive are set to 'full control'. The current owner on this drive is the 'DOMAIN\Administrators' group. I am an administrator myself and my account is a member of 'DOMAIN\Administrators' and even i get the same 'you need permission to perform this action' message. Even when i try to create a new shared folder on the server and map the drive, i get the same error.

This user has 6 network drives mapped to her account. Out of those, 4 other drives allow here to add, edit and delete files without any issues, except the other 2 which seem to be causing problem to her and myself. I have checked the settings of these working shared network drives and cant see anything different. The pictures below however are what i have mapped to my own administrator account and it still asks for Administrators permission even though i am an administrator!?

I haven't attempted a restart of the server yet. Current Server architecture is Windows 2012 R2

Remote user unable to access shared drive

DC/File server is 2008 R2. Client uses Windows 8.1 joined to the domain and is almost permanently working remote.

I have a file share on the server and folders in it. Access Based Enumeration is turned on for the share so users only see what folders they have access to.

Users in the office can access folders inside share no problem. This user connects via VPN and gets an access denied when trying to open the share. However she can open the Netlogon and Sysvol shares on the server, but not the file share. This user is a member of the same groups as other users who do not have the problem, but are onsite. This happens if the user logs into to the PC and connects the VPN or at the logon screen activates the VPN which then logs her into the PC.

What am I missing here? I've done this many times before and have never run into this.

Should ReFS be used without Storage Spaces?

To my understanding, ReFS can't repair detected file or metadata corruption unless it's hosted on a Storage Spaces volume.  Assuming this is true, it stands to reason that ReFS should not be used unless hosted on Storage Spaces volume.  Is this accurate?

New-DFSNRoot Access Denied Error on 2012 R2 (2003 Forest/Domain)

Hi All,

I'm unable to create a working DFS-N root using New-DFSNRoot.  The runs without issue and the DFS-N is visible but if I then try to issue a New-DfsnFolder I get the following;

New-DfsnFolder : Access to a CIM resource was not available to the client.
At line:1 char:1
+ New-DfsnFolder –Path "\\example.com\Root1\Folder1" -TargetPath $SMBSourc ...
+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    + CategoryInfo          : PermissionDenied: (MSFT_DfsNamespaceFolder:Root\Microsoft\...NamespaceFolder) [New-DfsnFolder], CimException
    + FullyQualifiedErrorId : MI RESULT 2,New-DfsnFolder

If I attempt to add the folder via the MMC I get;

\\example.com\Root1\Folder1: The folder target \\fileserver1\Folder1 cannot be added to the folder.  Access is denied.

Creating the Root and Folder using the MMC alone works without issue.  I'm running the powershell from a 2012 R2 box on a 2003 functional level forest/domain (so the DFS-N root can't be in 2008 mode).

When looking at the object in ADSI edit (CN=Root1,CN=Dfs-Configuration,CN=System,DC=example,DC=com) and comparing to another root created using the MMC the security permissions appear to be lacking an entry for the root server (permission to read/write all properties).  When the permissions are manually added (and permitted to propagate) the I am able to add a folder to the namespace using both powershell and mmc.

So I guess my question is can anybody else confirm this issue or is it something specific to our environment?

Scripting techniques for shares on Windows 2008 R2 Clustered File Server

Scenario: Windows Server 2008 R2 Clustered FS, two nodes.

Needs: I have to move all file system structure from a clustered disk to another, then recreate all shares and quotas.

Now I had found an unsopported way to backup quotas by saving disk "System Volume Information" and restoring on new disk.

About shares: is there any way to script shares export and import when configured at cluster level? Unfortunately I can't use Get-SmbShare and Set-SmbShare because they're included only from Windows Server 2012.

Any advice about it?

DFS Advice

October 1, 2015, 4:30 am

Looking for some guidance on how we should setup some new infrastructure we've recently purchased as part of a SAN replacement project.

Current setup is that we have multiple virtual Windows 2003 file servers that have Domain DFS Roots on them.

We've purchased 4x HP StoreEasy 3830's which are setup as 2+2 node clusters. One cluster is at our production site and one is at our DR site.

We're migrating all of the DFS roots and data on to these and are hoping to have high available/seamless transition between sites if we need to invoke DR.

We're quite confident on how we can setup the live site by using file server cluster services but are a little unsure on how to setup the DFS for the DR site.

We also use Access Based Enumeration on the Server 2003 which has resulted in us having to cacls commands to apply NTFS permissions to each DFS Link created.

1. Can anyone recommend or provide any links to how we can setup the two clusters so DFS/data is replicating and accessible?

2. Even if we get the data replicating, will we have an issue with the ntfs permissions on each DFS link, because the cacls command points to the local server/cluster name if we fail over connections to the second cluster it all changes and the permissions will not be in place? How can we resolve this issue?

Thank you in advance

High disk write percentage

What could be causing the write percentage to be very high on my 2008 R2 servers? I ran diskmon to see what the disk activity looked like and it's almost all writes, even when I'm the only user logged in and not running any programs. I am not seeing any performance problems, latency, etc, but it strikes me as odd that there is so much writing happening. I'm also not seeing any problem with disk space being used up, so it must be processes that are constantly overwriting something?

I'm seeing the same type of activity on physical servers and VMs. The VMs are on an equallogic san, and SanHQ shows above 95% write percentage pretty consistently on the Windows server LUNs. FWIW. most of these servers are in their own LUNs, and they are separate from the data LUNs.

Is this normal?

File name too long cannot copy (cont'd)

This is an addendum to locked forum File name too long cannot copy.  Just want to share what worked for me.

On a file server running Windows Server 2008 R2, I ran into this issue for only two files at the same path.  I was trying to move them to a different local drive while maintaining the exact same file structure.  After reading the entire thread referred to above, I tried the method in which a user mapped a drive to the parent folder of the affected file(s).  Here's how my dilemma played out:

  • The file names lengths were 231 & 230, including their extensions.
  • The parent folder path length = 40 yielding 271 for the longest path.
  • Source: E:\users\<8-char user name>\<7-char dir name>\<13-char dir name>\
  • Destination: "G" drive with same file structure.

Steps taken:

  1. Made the file structure on G: the same as the source.
  2. Shortened the names of the folders in the source folder's path; luckily, there were only two.  It became this:
    E:\users\<8-char user name>\<1-char dir name>\<1-char dir name>\
  3. File structure of destination remained intact.
  4. Mapped a drive to each path.
  5. Was able to perform usual operations on the files; in this case, I moved them.

I didn't care to open them because I had accomplished my goal and the user account to which this home folder was associated was already in the disabled state.  THE END...and a very happy one at that! :-)

EDIT: The computer from which I mapped the drives was running Windows 7 Enterprise SP1, 32-bit.

copying files larger than 2GB getting error

hi

I'm having a problem with large file transfers (2GB+) between server 2003R2 32bit and server 2008R2 64bit

If I attempt to push a 3.5GB file from the 2008R2 x64 server to a network share on the 2003R2 x86 server, the copy fails just after the 2GB point in the file and gives an error dialogue box

"Cannot copy <file>: The specified network name is no longer available"

If I attempt to push the same file between a 2003R2 x32 server to the same location (i.e. server platform matches) the copy succeeds

The same behavior occurs if I attempt to pull the file using the server 2003R2 x86 server, pulling from the 2008R2 x64 server gives the same error dialogue, pulling from another 2003R2 x86 server succeeds

All firewall and antivirus products and services have been disabled to eliminate them as being factors

At a bit of a loss, I get that x86 to x64 allows more RAM to be addresses, but as far as I knew, the NTFS file system was more or less the same ?

Anyone any ideas ?

Windows Server 2012 R2, running restore-dfsrpreservedfiles, getting path, file name or both are too long error

Trying to recover some deleted files that are located in the DFSRPrivate folder as Conflicted files due to an erroneous change made on the primary server in the replication group.   I am getting the error shown below when I try to recover those files (which are listed in the manifest file).   Is there any workaround/solution to getting these files back using this mechanism?  I am trying to do recovery to a different folder so I can copy from it, but running with RestoretoOrigin gives the same error.  

Alternatively, if there's a way to de-obfuscate the files in the DFSRPrivate directories, that might be a reasonable plan C.

Initially tried to do a disk based recovery from the primary server, but there are differences.   Server is Windows Server 2012 R2 64 bit.

Any suggestions would be gratefully received.

Hi, I am having a problem with shadow copy on Server 2008 R2, when restoring files, on some files I get the path too long, destination does not support this etc etc message. The thing that is confusing me is......the files were there originally and worked perfectly fine, yet if I try and copy them back into the folder from shadow copy I get this error message, I am literally just trying to restore some files and folders that where there the day before.

Bizarre DFSRoots subfolder permission inheritance issue

October 2, 2015, 3:35 am

Hi, I really hope somebody can shed some light on this...

Once in a while we get an issue where some (and sometimes all) users get niggling issues, such as the 'Documents' link in Start Menu not working (other issues within various applications also crop up at the same time).

We have various namespaces set up on our domain, one of which is called \\stockportgrsch.net\userfiles.
There are 3 namespace servers for this namespace (FS04, FS05 and FS06).

When the above issue arises, if I look at the permissions for 'C:\DFSRoots\Userfiles' on each of the servers, I will find that on at least one of them (and again sometimes all), permission inheritance seems to be broken.
By broken I mean that only 'Administrators' are showing in the ACL, but when I look at inheritance it thinks it's turned on.
The only fix I have at present is to click 'Disable Inheritance', click Apply, and then click 'Enable Inheritance'.
This puts the permissions back correctly, as below.
I know I can do this every time but can't keep checking this and obviously am worried that this might be a symptom to a wider issue!

Symbolic link type changed

We have been using symbolic intensively to archive historic files. An automatic script would create symbolic links regularly based on certain criteria. Users don't experience inconvenience as the soft links can be opened as regular files, programs will run without issues, and the type of those soft links are identical to the type of file it has a link to (for example, a symbolic link to an Excel file will have Excel file type in its properties). However, recently we have noticed that the type of links has changed to SYMLINK which makes Windows to ask users to choose what program to open with by popping up the "Open With.." window.

Do you guys what will affect the file server to change its behavior and represent symbolic links type as SYMLINK and create additional troubles?

Below PowerShell command shows number of users currently accessing a share.  Similarly, on Windows Server,  is there a way to find list of shares being accessed by a given user. 

PS C:\> Get-SmbShare | Select Name, Path, CurrentUsers

Name                                    Path                                                               CurrentUsers
