Delay with files showing on mapped drive

November 1, 2016, 9:19 am
$

Windows Server 2012 Standard with Windows 7 Pro desktops.  I have one user save a file to a mapped drive location (n:\folder\folder\file.txt for example), and there can be up to a 10 minutes delay on another user being able to see the file is there.  The second user can try to view the file via open file dialog boxes or Windows Explorer with no success.

This might not seem like a huge issue, but the user's workflow is being delayed enough that managers are getting involved wanting to know why this is happening.

I've enabled shadow copies schedule on a server for 10pm every-night of the week.  I'd like to do something custom with the retention of these shadow copies.  Something like:  Saturday-Thursday, keep for 20 days, and Friday keep for a year.  Is there any way to accomplish this?

Many thanks,

Encrypting shared folders (and the files in them) on a file server

November 1, 2016, 4:31 pm

As a part of our cyber security program we are thinking about encrypting certain sensitive data we have on our network file server. The folders are secured by ACLs so that only those employees who need to access that data has permissions to do so. However, if we had a hacker inside the network, he/she could find that data and steal it. Basically we are looking to secure that data even if it was somehow taken.

Currently that server is still running Windows 2003 but that can be changed to 2008 or 2012.  All workstations are on Win 7 Pro.

Is EFS a viable solution?  Or would a 3rd party solution work better?  We would prefer it to be as transparent to the end user as possible and of course the files would have to be accessible to those users with permissions to those folders. We're not interested in encrypting the entire drives, just specific folders.

Thanks.

additional inherited permissions of user already in a group

Sorry for my bad english i will try to describe the question with a few words.

A folder has a permissions group named "AE", this folder cannot be deleted by the users who are in this group, the users has the ability to create or delete everything to subfolders or files. If a user create a new folder or a new file or copy from another location an extra independent permission added to the new file or folder with Full Control rights.

With my account (my account has domain admins rights) added to "AE" group the server does not add anything.

My question full is:
is that a normal behavior of Windows Server security?
why the server does not add extra permissions with my account?
if this user or another user be removed from this group what happens to the files or folders that has his full control permissions?

thank you

External HDD connection

Hi Microsoft,

Just want to ask for your help.

We have an existing Windows 2012 r2 Server (HP). On this server, there are 3 external HDD attached and shared over the network.

It is working for quite sometime, but last weekend, we got this problem where in all those 3 external HDD connections are fluctuating. When I logged in to the server, the drive is disappearing and appearing.

Because of that, I have decided to transfer the external to other server where I can still share them over the network. And it is working fine there without the issue.

I original server where these external HDD's are hosted is still problematic. I tried attaching 3 USBs on it (without doing any sharing) and the issue is still persist. The drive letters of the USBs are disappearing and appearing continuously.

Here are the logs that I've gathered:

Also, we have found logs that may be related to this.

 

Log Name:      Application

Source:        SRMSVC

Date:          10/31/2016 5:02:50 PM

Computer:      XXXXXXX

Description:

File Server Resource Manager was unable to access the following file or volume: 'G:'.  This file or volume might be locked by another application right now, or you might need to give Local System access to it.

I hope you can advise me on what to do to the problematic server.

Thank you,

DFS: Can't create domain-based namespace, and 2008 mode checkbox is greyed.

WS2012 servers, WS2008 domain & functional level. Single-label domain...don't know if that's relevant.

DFS role is installed on 2 DCs, and intent is to make them namespace servers. However, when I try to create a DFS Namespace, I get this message when I click "Next" in the Namespace Type page:

---------------------------
Error
---------------------------
\\AVSIAV\DFS: The namespace cannot be queried. The RPC server is unavailable
---------------------------
OK  
---------------------------

Further, the "Enable Windows Server 2008 Mode" checkbox is dimmed and can't be selected. Functional levels were raised to WS2008 years ago; many DC reboots since then.

Same issues with both DCs. DFS services is running.

The C:\DFSRoots folder is not being created. Permissions on C:\ are Windows default, so the problem would appear to be that it's not getting that far.

I've removed and reinstalled DFS; no change.

I have not found any Event Log errors that correlate with this.

DCDIAG likes what it sees.

TIA

One or more critical user mode components failed to satisfy a health check.
Hardware mechanisms such as watchdog timers can detect that basic kernel

Kernel components can extend watchdog timer functionality to user mode

DFSr Error 2213, Replication has not occurred in a long time

Our lone DC, I know bad form attempting rectify, has Error 2213. Which is when the server experience a dirty shutdown and DFSr was not allowed to properly perform its functions and now has not replicated. I know how to resolve the 2213, run the command given in the Error message. However replication has not occurred since June of 2014.

Brief: 1 Windows Server 2012 non-R2 VM, fully updated, happily running as the DC, File Server, and some other roles. The only one of each in the domain. It's always been the only DC and file server.

According to http://howdoicomputer.com/2013/02/technical-stuffsysvol-dfs-replication-annoyances/ the server will through another error once the Event ID 2213 command is run in a command prompt. This error, most likely 4012, will state that replication cannot occur do to the time since the last replication has exceeded the allowed time set in the MaxOfflineTimeInDays parameter, which is by default 60 days. In the article the author gives how to resolve this, change the parameter to be a day or a few days farther in the past than when the last replication occured, simple enough. I've seen comments on that page that state that solved their issue(s), however they were in the 60 to 200 day ranges, not 2 years of days.

Trying to get opinions on whether this will solve our issue, or if there is another better way. 

Thanks all in advance.

Storage Replica Stretch Cluster

November 2, 2016, 3:29 am

Storage Replica looks really good, and I've been waiting for this feature for a long time.

Having been investigating it since TP5 I've now got the RTM Server 2016 installed and have been looking at setting up an improved file server platform.

I have multiple offices plus a datacenter, and want to create clusters with a node at each office, replicating back to the datacenter.

The idea being that the preferred node for each cluster will be the node located in the office, with the datacenter node being the fallback for if the office is offline. The data would thus be located on the office LAN, near the user, unless the office is out of action, in which case the users will work from elsewhere and get the data from the datacenter via a WAN/VPN connection.

Storage Replica can replicate the data, but it looks like I can only create a cluster that spans sites if I have a working cluster at each site? In other words: single server to single server, with storage replica, seems like I can't create a cluster.

This documentation seems to back that up: https://technet.microsoft.com/windows-server-docs/storage/storage-replica/server-to-server-storage-replication?f=255&MSPPError=-2147217396

I suppose I'm just wanting to know, why can't I use SR to create a two node cluster where the nodes are on different sites? Or even different bits of kit using local storage in the same site?. If I can't, it seems to rather defeat the "shared nothing" primary feature of a stretch cluster? Or am I missing something?

One iSCSI LUN behind two Server

Hi All,

i have a QNAP TS421 NAS, we use it as iSCSI storage. Nowadays we're adding a new server. I connected an existing LUN on two server? Both of servers using the LUN for Read, Write, Sharing, etc. What if the servers are trying to manipulate the same file (for ex. Word doc, or same) and what if they don't disturbing the files of the other (VHD storage for HyperV)?

I mean, do I need have fear from corrupted files, dataloss, etc.?

If it's a document storage, what if I set up Shadowcopy on Server_A and do nothing (leave it disabled) on Server_B?

Thanks!
Peter

iSCSI with 2 Servers (Same LUN)

Current Setup:

  • dc1.domain.com and dc2.domain.com
  • FreeNAS configured with a LUN on a SAN
  • File & Storage Services Installed on both DCs
  • I have the FreeNAS connected to dc1 as a local disk.

My question is how can I have the same disk connected to both servers so that they are sharing the same LUN/data without doing a folder share?

Do I have to create a Storage Pool or a New iSCSI Virtual Disk?

DC unable to browse it's own shares

October 26, 2016, 2:48 am
$

Hi all,

This is my first post on here so i hope i can make sense for you lovely people to help me.

Setup is a Server 2012 R2 domain controller which had the following roles installed:

  • ADDS
  • GPMC
  • DNS
  • DHCP
  • File services
  • Print services
  • WDS (also running MDT)

No i appreciate that this is not MS best practice but our clients have limited budget for servers and licenses etc.

The initial issue is that the server experienced an infiltration of a virus/cryptolocker from which their files were restored from backup. However since then, the DC itself cannot access any of it's shares or DFS but domain joined clients can, aswell as the host. The DC receives the error:  "*share* is not accessible. You might not have permissions to use this network resources. Contact the administrator of this server to find out if you have access permissions. The specified network name is no longer available."

The share and network name is available if you are not on the DC.

I proceeded to make a new DC (DC2) which also ran DNS. I have moved the operations master roles to this server but this has made no change.

Looking forward to your suggestions.

Thanks,
Ollie.

Windows refuses to mount a read-only disk

Hi!

We are launching a virtual server business under the SPLA. We'll be running Windows Server 2012 R2 under OpenStack with KVM virtualization. It works fine, but we already have a backup and restore service for Linux, which mounts virtual disk snapshots read-only. We wanted to use the same for Windows.

When Windows is presented with a hot-plugged SCSI device which is read-only, it marks it as failed, doesn't show any partitions, doesn't allow to online it, and of course cannot clear the read-only flag, as most articles on the 'net suggest.

Any tips to make this work? Or is there and inherent limitation of Windows so it won't work no matter what we do?

Thanks, Tomas, homeatcloud.cz

DFS: How to safely remove one server from the namespace?

November 3, 2016, 6:48 am
$

0

Hello,

I'm looking for advice on safely removing a DFS server from an existing namespace.

Server A:   Server 2003.   Used to be the main DFS server but we've added 2 new servers and moved the share data over to them and we're trying to decommission Server A  without interrupting anything.  Server Referral status is set to 'Enabled'.

Server B and Server C:  Both Server 2012 R2, our main DFS servers, but server referral status is set to Disabled.  Each of these servers is at a different site and set up to be at different sites in our Active Directory tree

DFS share data is no longer being written to Server A and Server's B and C are doing the file sharing.   Replication is turned on and is correctly working between servers B and C which are at different physical locations/sites.    Server A is doing nothing at all, except being listed as a server on our company's namespace (Domain.local\Files).      Active directory is used on our domain, but none of these servers are acting as domain controllers.

I was planning on doing this:

  • In Server 2008's DFS Management, set Server B and Server C's referral statuses to 'Enabled' and set Server A to 'Disabled.'
  • In Server 2008, run:   dfsutil diag unmapdomroot \Domain.local\Files \ServerA\Files
  • If Server A is still listed as a namespace server in DFS Management after this, R.Click it and select Delete

QUESTIONS:

  • Would this plan work?
  • Do I even need to use command line commands for this, or can I simply delete Server A from the namespace via the DFS Management GUI?
  • Folder Target Referral Status are enabled for the shares on servers B and C.   Does at least one server need to have Server Referral Status set to enabled?

Thank you.
