Windows Server 2012 R2 file sharing

How can I put File Sharing on in Windows Server 2012 R2? Every time I put it on, the next time ita off again.

Hi Nikorios,
This issue occurs for one of the following reasons:
The dependency services for Network Discovery are not running.
The Windows firewall or other firewalls do not allow Network Discovery.  
You could refer to the article below to resolve the issue:
You cannot turn on Network Discovery in Network and Sharing Center in Windows Server 2008, Windows Server 2008 R2, or Windows Server 2012

  • Windows server 2012 R2 file server for windows XP machines?

    I know that we can't auto enroll users that use an XP machine, but can an XP machine use the windows server 2012 R2 as a file server? Users will still be authenticated on a windows server 2003 machine.

    Hi,
    I found this article on Symantec website:
    Enterprise Vault 10.0.3 Feature Briefings - FSA support for Windows Server 2012
    http://www.symantec.com/business/support/index?page=content&id=DOC6307
    So the newest version should support Deduplication (at least on Windows Server 2012) now. 
    And for best practice, do you have any specific requirement? It actually depends on necessary. 
    If you have any feedback on our support, please send to [email protected]

  • Windows Server 2012 - Page File Recommendations

    I need to know Microsoft's recommendations for the page file settings in Windows Server 2012. In previous versions of windows it has been calculated at 1.5 x RAM but i cant find any recommendations when it comes to Server 2012. 

    The rules/practices for setting page files  on virtual memory systems has remained the same for years and years.  What has changed is the cost to implement a solution.  As noted earlier, the old method of calculation was built on the fact
    that memory was an expensive commodity when compared to the cost of the disk.  Even back then, when memory was so expensive, the best solution was still to add memory.  But, people wanted to implement a less costly solution.  Microsoft published
    an article for Windows XP/Windows Server 2003 64-bit.  Nothing in the process of determining the optimal page file has changed, but the cost of the solution has changed.  Therefore, you can follow the instructions in this Microsoft support article
    - http://support.microsoft.com/?id=889654 - to determine the appropriate page file size.  If you want to really learn about what is going on, read
    http://blogs.technet.com/b/markrussinovich/archive/2008/11/17/3155406.aspx.  I think you should be able to trust Mark Russinovich' word.
    Today, for servers with 64 GB of RAM, I generally set up a page file of 2-4GB.  On a server with 256 GB of RAM, I set up a page file of 2-4 GB of RAM.  This is because Microsoft also included new capabilities in what is captured, allowing you to
    capture just the most important stuff that is in memory when the system crashes instead of all memory.  Windows operates most efficiently if it has a page file.  The thing is that if you have enough memory on your system to run the load you are putting
    on it, the primary purpose of sizing the page file comes down to determining how much of the memory you want to capture should the system crash.  If I am running something like Hyper-V, and I have 256 GB of memory, almost all that memory is allocated
    to VMs.  That means that the contents of that memory is totally useless to find the root cause of a crash.  That information is most likely going to be found in the first 512 MB of memory.  Switch to a different application like SQL.  In
    the case of SQL, again, the operating system is taking up the first part of memory and SQL is generally using the rest of memory as cache.  What is in cache is of little or no interest to determine why the system crashed, so why build a page file to capture
    it?

  • Windows Server 2012 R2 File Server

    I updated my file server to Server 2012 R2 and everything went ok except now my windows 8 clients cannot connect to the file server.  I get a generic error An extended error has occurred when I try to unc to it and none of my drives will map.  Did anyone else have an issue like this?
    The file server is a virtual server running on Hyper-V and the file storage comes from a San iscsi drive.
    Thanks for any help with this issue.

  • Hyper-V 2012 High Availability using Windows Server 2012 File Server Storage

    Hi Guys,
    Need your expertise regarding hyper-v high availability. We setup 2 hyper-v 2012 host in our infra for our domain consolidation project. Unfortunately, we don't have hardware storage that is said to be a requirement that we can use to create a failover cluster
    for hyper-v host to implement HA. Here's the setup:
    Host1
    HP Proliant L380 G7
    Windows Server 2012 Std
    Hyper-V role, Failover Cluster Manager and File and Storage Services installed
    Host2
    Dell PowerEdge 2950
    Windows Server 2012 Std
    Hyper-V role, Failover Cluster Manager and File and Storage Services installed
    Storage
    Dell PowerEdge 6800
    Windows Server 2012 Std
    File and Storage Services installed
    I'm able to configure the new feature about Shared Nothing Live Migration - i'm able to move VM's back and fort between my hosts without storage. But this is planned and proactive approach. My concern is to have my hyper-v host to become highly available in
    the event of system failure. If my host1 dies, the VMs should go/move to host2 and vice versa. In setting this up, i believe i need to enable the failover clustering between my hyper-v hosts which i already did but upon validation, it says "No disks
    were found on which to perform cluster validation tests." Is it possible to cluster it using just a regular windows file server? I've read about SMB 3.0 and i've configured it as well i'm able to save VMs on my file server, but i don't think that my hyper-v
    hosts are already highly available.
    Any feedback and suggestions or recommendation is highly appreciated. Thanks in advance!

    Your shared storage is a single point of failure with this scenario so I would not consider the whole setup as a production configuration... Also setup is both slow (all I/O is travelling down the wire to storage server, running VMs from DAS is ages faster)
    and expensive (third server + extra Windows license). I would think twice about what you do and either deploy a built-in VM replication technologies (Hyper-V Replica) and apps built-in clustering features that does not require shared storage (SQL Server and
    Database Mirroring for example, BTW what workload do you run?) or use some third-party software creating fault tolerant shared storage from DAS or investing into physical shared storage hardware (HA one of course). 
    Hi VR38DETT,
    Thanks for responding. The hosts will cater a domain controller (on each host), Web filtering software (Websense), Anti-Virus (McAfee ePO), WSUS and an Auditserver as of the moment. Is the Hyper-V Replica somewhat give "high availability" to VMs or Hyper-V
    hosts? Also, is the cluster required in order to implement it? Haven't tried that but worth a try.

  • Windows server 2012 standard - slow performance in file sharing

    I recently installed two windows server 2012, one is for DC, one is for File Sharing; it works fine in the beginning.
    Lately, it comes a problem, every once a while it is very slow when opening a file on the server from a client PC; but when i restart the file server then  it will be fine again.
     

    Hi Simon,
    Based on your description, how is the workload of the file server?
    Before going further, regarding slow network performance when opening a file that is located in a shared folder on a remote network computer, the following article can be
    referred to as reference.

    Besides, the following thread may have focused on the similar issue and can be worth taking a look.

  • Windows Server 2012 Windows Backup failed with following error code '0x8078006B' (Windows Backup failed to create the shared protection point on the source volumes.).

    The Volume Shadow Copy service initially was running under the context of System, so we thought that ‘System’ doesn’t have permissions to access network shares. 
    When the Volume Shadow Copy service was running under the context of System, this was the error logged:
    “failed with following error code '0x8078014B' (There was a failure in creating a directory on the backup storage location.).”
    Which is likely due to not having permissions to write to the network location. 
     This is a scheduled backup trying to write to a network location, so we changes the service to run under the context of an account that does have permissions to write to the network share.
      Then the error changed to this:
    “failed with following error code '0x8078006B' (Windows Backup failed to create the shared protection point on the source volumes.).”

    We aren’t really seeing anything that gives any hint on what the issue is. 
    Any ideas?  Thanks in advance!

    We are trying to back up folders/files from 2 local drives (C: & D:), both of which have only 10% space used, and 100 GB free. 
    We are attempting to back the files up to a Remote Shared File (and there is 100+ GB free space out there). 
      If we try another network location, we receive the exact same error. 
     This is Windows Server 2012, not running Hyper-V and is a physical server not a VM.
    Thank you for the link.

  • Cluster Quorum Disk failing inside Guest cluster VMs in Hyper-V Cluster using Virtual Disk Sharing Windows Server 2012 R2

    Hi, I'm having a problem in a VM Guest cluster using Windows Server 2012 R2 and virtual disk sharing enabled. 
    It's a SQL 2012 cluster, which has around 10 vhdx disks shared this way. all the VHDX files are inside LUNs on a SAN. These LUNs are presented to all clustered members of the Windows Server 2012 R2 Hyper-V cluster, via Cluster Shared Volumes.
    Yesterday happened a very strange problem, both the Quorum Disk and the DTC disks got the information completetly erased. The vhdx disks themselves where there, but the info inside was gone.
    The SQL admin had to recreated both disks, but now we don't know if this issue was related to the virtualization platform or another event inside the cluster itself.
    Right now I'm seen this errors on one of the VM Guest:

    We don't know if this can happen again, what if this happens on disk with data?! We don't know if this is related to the virtual disk sharing technology or anything related to virtualization, but I'm asking here to find out if it is a possibility.
    Any ideas are appreciated.
    Thanks.

  • How to convert VHDX to VHD file format on windows 8 / Windows server 2012?

    Here is an article to describe how to convert virtual hard disk VHDX file format to VHD 
    http://anuraggawande.blogspot.in/2012/10/vhdx-to-vhd-conversion.html

    Hi,
    Thanks for sharing the web link!
    You help other community members who facing similar problems.
    Thanks for your contribution to Windows Server Forum!
    To convert VHD format, you can also use Convert-VHD comlet. The Convert-VHD cmdlet converts a virtual hard disk file by copying the data from a source virtual hard disk file to a new virtual hard disk file of a specified format and version type. The format
    is determined by the file extension of the specified files, either .vhdx or .vhd. Conversion is an offline operation; the virtual hard disk must not be attached when the operation is started.
    For more information please refer to following MS articles:
    Convert-VHD

  • Windows Server 2012 very slow performance executing files

    Hello,

  • Cannot publish Flash Updates Verification of file signature failed for file SCUP 2011, SCCM 2012 R2 and WSUS all on same Windows Server 2012 machine

    I am attempting to distribute Adobe Flash updates using SCUP 2011, SCCM 2012 R2, WSUS ver4 and Windows Server 2012.  Everything installs without error.  I have acquired a certificate for SCUP signing from the internal Enterprise CA.  I have
    verified the signing certificate has a 1024 bit key.  I have imported the certificate into the server's Trusted Publishers and Trusted Root CA stores for the computer.  When I attempt to publish a Flash update with Full content I receive the following
    error:
    2015-02-13 23:00:48.724 UTC Error Scup2011.21 Publisher.PublishPackage PublishPackage(): Operation Failed with Error: Verification of file signature failed for file:
    \\SCCM\UpdateServicesPackages\a2aa8ca4-3b96-4ad2-a508-67a6acbd78a4\3f82680a-9028-4048-ba53-85a4b4acfa12_1.cab
    I have redone the certificates three times with no luck.  I can import metadata, but any attempt to download content results in the verification error.
    TIA

    Hi Joyce,
    This is embarrassing, I used that very post as my guide when deploying my certificate templates, but failed to change the bit length to 2048.  Thank you for being my second set of eyes.
    I changed my certificate key bit length to 2048, deleted the old cert from all certificate stores, acquired the a new signing cert, verified the key length was 2048, exported the new cert to pfx and cer files, imported into my Trusted publishers
    and Trusted Root Authorities stores, reconfigured SCUP to use the new pfx file, rebooted the server and attempted to re-publish the updates with the following results:
    2015-02-16 13:35:44.006 UTC Error Scup2011.4 Publisher.PublishPackage PublishPackage(): Operation Failed with Error: Verification of file signature failed for file:
    \\SCCM\UpdateServicesPackages\a2aa8ca4-3b96-4ad2-a508-67a6acbd78a4\3f82680a-9028-4048-ba53-85a4b4acfa12_1.cab.
    Is there a chance this content was already created and signed with the old cert, so installing the new cert has no effect?  In ConfigMgr software updates I see 4 Flash updates, all marked Metadata Only (because they were originally published as "Automatic." 
    No Flash updates in the ConfigMgr console are marked as downloaded.  I can't find any documentation on how the process of using SCUP for downloading content for an update marked Metadata Only actually works. 
    Comments and suggestions welcome.

  • Shared Computer Licensing on Windows Server 2012 R2

    Hello All,
    I've installed Office 365 onto our Windows Server 2012 R2 server. Everything went through fine. I used the following configuration file:
    <Configuration>
      <Add SourcePath="location it's saved" OfficeClientEdition="32">
        <Product ID="O365ProPlusRetail">
          <Language ID="en-us" />
     <ExcludeApp ID="Access" />
     <ExcludeApp ID="Groove" />
     <ExcludeApp ID="InfoPath" />
     <ExcludeApp ID="Lync" />
     <ExcludeApp ID="Project" />
     <ExcludeApp ID="SharePointDesigner" />
     <ExcludeApp ID="Visio" />
        </Product>
      </Add>
      <Updates Enabled="True" UpdatePath="\place that it is located" />
      <Display Level="Full" AcceptEULA="TRUE" />
      <Logging Level="Standard" Path="%temp%" />
      <Property Name="SHAREDCOMPUTERLICENSING" Value="1" />
    </Configuration>
    After the installation I am able to access Word 2013, etc. Once I log off of the server, and go back on I am no longer able to access Word 2013, etc. I am getting the following error:
    "Sorry we are having some temporary server issues" And it loops if you click try again. Click on cancel, and we get "Microsoft Office can't find your license for this application. A repair was unsuccessful, or was cancelled. Microsoft
    Office will now exit."
    I've checked the registry at HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Office\15.0\ClickToRun\Configuration 
    and it is there.  No files were in %localappdata%\Microsoft\Office\15.0\Licensing.

    Hi,
    It seems to me that Office was trying to connect to the Internet for licensing, but somehow cannot connect to the server.
    The error "Sorry we are having some temporary server issues" is vague, the most likely cause of the error is blockage of access to certain ports. Please first check if your firewall setting/antivirus program is blocking any Office 365 IP addresses
    or ports:
    http://technet.microsoft.com/en-us/library/hh373144.aspx
    Some users also reported that they were able to get rid of this by switching to a different network connection, so probably you might also want to have a try.
    Hope this helps, please feel free to post back with any findings.

    It's recommended to download and install

  • File systems available on Windows Server 2012 R2?

    What are the supported file systems in Windows Server 2012 R2? I mean the complete list. I know you can create, read and write on Fat32, NTFS and ReFS. What about non-Microsoft file systems, like EXT4 or HFS+? If I create a VM with a Linux OS, will
    I be able to acces the virtual hard disk natively from WS 2012 R2, or will I need a third party tool, like the one from Paragon? If I have a drive formated in EXT4 or HFS+, will I be able to acces it from Windows, without any third party tool? Acces it,
    I mean both read and write on them. I know that on the client OS, Windows 8.1, this is not possible natively, this is why I am asking here, I guess it is very possible for the server OS to have build-in support for accesing thoose file systems. If Hyper-V
    has been optimised to run not just Windows VMs, but also Linux VMs, it would make sense to me that file systems like thoose from Linux or OS X to be available using a build-in feature. I have tried to mount the vhd from a Linux VM I have created in HyperV,
    Windows Explorer could not read the hard drive.

    Installed Paragon ExtFS free. With it loaded, tried to mount on Windows Explorer a ext4 formated vhd, created on a Linux Hyper-V vm, it failed, and Paragon ExtFS crashed. Uninstalled Paragon ExtFS. The free version was not supported on WS 2012 R2
    by Paragon, if Windows has no build-in support for ext4, this means this free software has not messed around anything in the OS, I guess.
    Don't mess with third-party kernel-mode file systems as it's basically begging for troubles: crash inside them will make whole system BSOD and third-party FS are typically buggy... Because a) FS development for Windows is VERY complex and b) there are very
    few external adopters so not that many people actually theist them. What you can do however:
    1) Spawn an OS with a supported FS inside VM and configure loopback connectivity (even over SMB) with your host. So you'll read and write your volume inside a VM and copy content to / from host.
    (I personally use this approach in a reversed direction, my primary OS is MacOS X but I read/write NTFS-formatted disks from inside a Windows 7 VM I run on VMware Fusion)
    2) Use user-mode file system explorer (see sample links below, I'm NOT affiliated with that companie). So you'll copy content from the volume as it would be some sort of a shell extension.
    Crashes in 1) and 2) would not touch your whole OS stability.

    Ext2Read
    http://sourceforge.net/projects/ext2read/
    (both are user-land applications for HFS(+) and EXT2/3/4 accordingly)
    Hope this helped :)

  • Windows Server 2012 R2 RDS: RDS Users are unable to delete files from their desktop

    Hello,
    We are working with Windows Server 2012 R2 RDS. We also implemented User Profile Disks. This is all working fine without problems. The only issue I have is that normal users are unable to delete files from their desktop. They are getting a message:
    you'll need administrator permission to delete this file, with the prompt for administrator access.
    They can edit, copy, rename, cut and paste files. But they cannot delete a file from their desktop.
    I checked the security permissions of the files on the desktop (for example a normal self-created PDF file) and the users are owner and have "Full Control" over the files.
    I checked the file permissions and took a look under "Advanced", selecting the specific domain user and checked the "Advanced Permissions" and the user has the "Delete" option checked. So he should be able to delete the
    file.
    I am guessing this is UPD related issue, or something in GPO. But I already unlinked the GPO objects, that I felt could be the source of this problem, but without results.
    Could someone give me a hint on where to look? It's kinda annoying to users, that they can't delete their own files.

    Hello Bria,
    What you should check first, is the NTFS permissions on the User Profile Disk to begin with. See if the user has full control over the items that are in the UPD.
    Also check the GPO's that are enabled for the user and computer account. You can check that by running: gpresult /h <path>\gpresult.html
    There are two GPO settings that could prevent the user from deleting his/her own items: 
    User
    Configuration\\Policies\\Administrative Templates\\Windows Components\\Windows Explorer\
    Hide these specified drives in My Computer
    Prevent access to specified drives in My
    Computer
    There might be other GPO settings, that block deleting items on the UPD, but can't think of any out of my head.
    I can only think NTFS and GPO settings that might prevent the user from deleting items. In my case it was a GPO setting, that I didn't suspect.

    Hi Shaun
    Tried both of your suggestions, however neither strategy worked.
    Strategy 1
    Tried installing via powershell - "install-windowsfeature -name fs-resource-manager -includemanagementtools"   
    Feature un-installed itself during the restart.
    Attempted to use the command "DISM /online /remove-feature /featurename:FSRM-Infrastructure-Services".  However
    this did work because one the Service was'nt installed or two because there was no command option for "/remove-feature"
    PACKAGE SERVICING COMMANDS:
      /Add-Package            - Adds packages to the image.
      /Remove-Package         - Removes packages from the image.
      /Enable-Feature         - Enables a specific feature in the image.
      /Disable-Feature        - Disables a specific feature in the image.
      /Get-Packages           - Displays information about all packages in the image.
      /Get-PackageInfo        - Displays information about a specific package.
      /Get-Features           - Displays information about all features in a package.
      /Get-FeatureInfo        - Displays information about a specific feature.
      /Cleanup-Image          - Performs cleanup and recovery operations on the image.
    Strategy 2
    Tried installing via powershell, using the following command DISM
    /online /enable-feature /featurename:FSRM-Infrastructure-Services, however got the same result, the install backed out during the restart.
    All up back to where I started?
