Access denied in Windows 2012 Server Manager after a period of time working without problems

Hello,
I had 2 servers with windows 2012 installed in a domain (dc is in a 3rd server) and both added to server manager of each other. Both servers had Failover cluster installed and configured roles. After startup in both servers i can see the other and manage
it without problems (in server manager and failover cluster manages) but after a period of 30-40 minutes in both servers I see "Online - Data Retrieval failures Ocurred" for the partner server and "Online - Access Denied" for local server.
When I access de Failure Cluster Manager I had errors accessing resources and roles and can´t failover the cluster.
I removed the failover cluster thinking that could be the original problem, remove servers from domain, change names and add again to the domain without install failover cluster.
Now, the servers have not the failover cluster feature and the problem persists. 30-40 minutes after boot the server manager show messages of inaccesible partner with same messages. I tried to execute powershell commands to add a new ip to the NIC and I
receive a Access Denied Message and show Access Denied message in other events in log.
I´m using Domain Administrator Account and tried different solutions but not solved. I saw that this message can occur in a variety of different scenarios, but i don´t know why works during a period of time before failing. It´s frustrating
Regards
EDITED: in detail of Online - Data retrieval failures i see that: Configuration refresh failed with the following error: The metadata failed to be retrieved from the server, due to the following error: The WS-Management service cannot process the request.
The WMI provider returned an 'access denied' error.

Hi PabloVDL,
It seems is this two server has register the incorrect DNS, please try to add this server manage NIC IP to your manager hosts file or if possible trmpory disable the useless NIC DNS register. This issue also some times caused by when you installed
the HP insignth management, if in your environment you have this tools please temporarily uninstall it.

  • Access Denied In windows 2008 Server R2

    Hi team,
    I ma trying to implemet a Lab setup to impelment 2008 AD/DNS/DHCP and work on SCCM 2007 deployment concepts. We have two 2008 R2 server adn one Win 7 mahcine all in Workgroup environment.
    I tried to Promote one of the Server to DC. As the initial steps, i loaded the AD DS binary files in the mahcine and renmed the machine name to something accrording to DC standards. I did all this logged in with the defauld Administrator acct.
    We rebooted the machine and i cant login with the dafualt Administrator acct anymore. I am gettin Access Denied.
    I connected to the computer mgmt snapin remotely created a new user, added to administrators group,Remote desktop users group and can login with the newly created account. but not the Deafult Administrator acct. Have anyone come across similar issues. Please
    letme know what could be the issue, since i have never faced this issue before :-( :-(
    AppGN

    Hiya,
    It sounds like the following:
    1: When you started working with your server you were using your local Administrator account, doing everything on the server.
    2: When you promoted it to a DC, it no longer has a local Administrator account, but only a Domain Administrator account. You need to login using <Domain>\Administrator and not <ServerName>\Administrator. When you try to logon, it will have the
    previously used local administrator account as the account.
    3: When you remote connected you just wrote Administrator, which resolved to the domain administrator account, hence you were able to login and create the new account.
    That would be my guess :)

  • How To Increase TCP Connections in Windows 2012 Server

    We have installed our Java application in Windows 2012 Server. After running for some time application started showing Connection Time out. We have set TCP Parameters MaxUserPort = 65534 and TcpTimedWaitDelay = 30.
    We are facing the same issue, even after setting the parameters in windows registry. We have verified in our application, "There is no connection pool issue and no thread issue".
    We are using JDK v6.0.29, Tomcat 7, MYSQL 5.5.
    Apart from MaxUserPort and TcpTimedWaitDelay is there any other TCP parameters in Windows 2012 to improve performance of the server and our application.
    2) At the same time we have found that ‘There is sluggishness in I/O process’. Is there any registry parameters to improve I/O performance in the system.
    Thank You.

    hi. i have a windows 2012 server and it keeps closing after 30 mins...i am connected thru RDP and have looked everywhere online for a tutorial to change the setting that keeps closing it but can't find it anywhere! please help!

    Hi,
    Thank you for posting in Windows Server Forum. 
    Have you check the timeout and reconnection setting for RDP?
    Does disconnection happens on active session or Idle session? 
    We can configure the setting by collection properties or by GPO setting.
    On collection Properties check the Timeout Tab and set the setting according to your requirement. On GPO we can find this setting on below mention path and check according to it.

  • Windows 7 SP1 client file lock on network share hosted ny WIndows 2012 Server

    Hello
    I have one strange problem after migration from Windows 2003 Server to Windows 2012 Server R2 Standard. 
    All migration tasks went well but two things do not work.
    In Computer Management you have The Opened Files feature and if you open any file that is located on the network share hosted by Windows 2012 R2 form Windows 7 SP1 and then close it
    it remains open in the Opened Files tab (even if you wait an hour).  There is no problem with Windows XP SP3. The issue exist only with Windows 7.
    The session view of sessions to the file server do not work. If I try to open it I get the message that the application is not responding. 
    Can someone help me with that ?
    About the environment:
    It is one server Domain migrated form 2003 to 2012R2.
    The domain and forest level was raised to 2012 R2.
    I have made clean install of Windows 2012 R2 and then migrated AD. 
    Best Regards

    Hi Sebastian,
    >>There is no problem with Windows XP SP3. The issue exist only with Windows 7.
    T>>he session view of sessions to the file server do not work. If I try to open it I get the message that the application is not responding. 
    Based on the description, please check event logs in Event Viewer to see if there were some related events logged. Besides, does this phenomenon happen all Windows 7 clients? We can try to restart the client to see if it helps.

  • Windows 7 Client 'sees' an old version of windows 2012 server share

    Hi All,
    I have a problem which seems to be a common theme looking at other threads. Here's the overview of the problem:-
    I have multiple windows 7 clients and a windows 8.1 client within a 2008 Server in a domain.
    I also have a Windows 2012R2 Server which is not joined to the domain. There is a Share on the 2012R2 which has the Caching Option turned off. Everyone full control on Share & File permissions.
    One of the Windows 7 machines in Explorer when it looks at
    \\2012server\share sees an old version of the folder. It seems that SMB 2 chaching is working too well. Not even pressing F5 or clicking View, Refresh updates windows explorer.
    It took a reboot to get the workstation to see the up to date contents of the share on the 2012 server.
    We don't seem to have that behaviour with that client against the 2008 server.
    I have seen this behaviour on another machine un-related to us at another location which was in a workgroup with a 2012 server and no domain.
    Questions:-
    Is there some sort of problem with Windows 7 workstations working against 2012 Servers in a non-domain setting or is it just Windows 7 against 2012 servers period?
    I understand that Windows 7 utilises SMB1 & SMB2. SMB2 introduced caching. If the server has turned off the share cache option should the client cache the contents of the share or the information about the files & folders & 'file not found'
    information?
    I want to open a file handle to a file on a network share so I can read and write data to it. But I also want to know that when I look at the folder to open the file I'm actually looking at the live version of the folder and files in the folder and
    not a cached version of the folder. If it's a cached version the file might be there already but I won't see it.
    Is there an API call that tells the client to get a fresh view of the server share so I can be absolutely sure that when I look for a file on the server I'm getting the correct answer and not one from cache.
    I first posted the question with the same subject "Windows 7 Client 'sees' an old version of windows 2012 server share" in the Windows 7 Networking Fourm
    https://social.technet.microsoft.com/Forums/en-US/23bf3627-987b-4c27-8062-85a284a2cda4/windows-7-client-sees-an-old-version-of-windows-2012-server-share?forum=w7itpronetworking and it was suggested I repost in here. Please do take the time to read
    the thread which will save time with suggestions that have already been covered.
    As the computers that can be affected by this problem are not mine I cannot enforce or guarantee that any of my 'client base' will apply any hotfixes. I will also not have the ability to tweak registry settings as I can't guarantee Admin Access.
    It seems that we need to go back to SMB1 as all the tweaks to SMB since those days have introduced problems with the basic requirement of sharing files from a share on a server for Read/Write purposes. I have tried turning a network back to SMB1 and that
    has resolved a lot of the issues but then I found a post/MS blog that states not to leave the network on SMB1
    The Caching option of the share had already been turned off. Surely Windows clients should not cache any information about the share but I think that is not the case.
    Thanks is advance
    Robert

    Hi Shaon,
    Thanks for looking into this.
    If this is a known issue, why isn't the hotfix rolled into a general windows update if this is a known problem? However this doesn't just affect domain joined workstations.
    Surely it's basic functionality for a networked computer to access files and folders on a network file server. It's what networks were invented for at the end of the day.
    I am unable to apply hotfixes to these computers that are having the problem due to the fact they are not mine but my customers.
    At one of my customers sites I disabled SMB2 from the server and network clients as well as disabling the network adapter power saving option. This seemed to resolve the issues that I saw on one client that seemed to be 30 minutes behind the rest of
    the network.  The hotfix you link to states that it is for Domain joined computers. At my customer site the PC's are not in a domain at all, just a workgroup with workstations and a 2012r2 server. Will the hotfix be applicable to non-domain machines?
    Also many clients seemed to loose the file handle to an open file on the server. I'll get them to turn SMB2 back on at some point after I send out some updates but all the problems I see seem to be caused by the caching functions in SMB2. SMB1 is good and
    stable. It's SMB2 that seems to be causing the problems as it was designed from the ground up for caching.
    Has this networking issue been resolved in Windows 8, 8.1 and 10?
    As I am unable to apply a hotfix to 1000's of PC's that are not mine, is there an API call or something where I can get the windows client to stop lying and get me the current state of a folder on the server?
    Will Turning off ClientSideCaching fix the issue? HKLM\SYSTEM\CurrentControlSet\Services\MrxSmb\Parameters\
    CSCEnabled
    Or will every machine need to be tuned individually according to the following guide:-

  • Install Remote Desktop Services Failed on Windows 2012 Server

    I understand RDS is not recommended on DC due to security consideration.  However since I want to play it at home, it is not much a concern.  Such scenario works fine on Windows 2008 R2.  But on Windows 2012, the RDS (session-based, have not
    tried VDI, but expect same result) installation always fails and is incomplete on DC. 
    In \Administrative Tools\Terminal Services, I only have RD Licensing Diagnoser and RD licensing manager.  The remote desktop service management service cannot be started (Error code: 0x88250001).  Is there any extra configuration needed for RDS
    working on Server 2012 DC or before the installation?  Thanks.
    Update: this issue has been solved in Windows 2012 R2 Server.  According to
    http://blogs.msdn.com/b/rds/archive/2013/07/09/what-s-new-in-remote-desktop-services-for-windows-server-2012-r2.aspx
    "Single server RDS deployment including Active Directory. We now support running our RD Connection Broker role service on the same physical instance as an Active Directory Domain Controller.  In addition, we published
    guidelines for how RD Session Host could be used without the RD Connection Broker."
    The guidelines (http://support.microsoft.com/kb/2833839/en-us) primarily apply to Windows 2012 Server.

    Asinine.  Simply Asinine.  Microsoft took it out because of $GREED$.  
    RemoteDesktop has become so popular, they had to break it to make more money.  Thats why they discontinued SmallBusinessServer.   If this practice is so tabooo... Why did MS go the opposite direction with SBS 2011 Premium Cal's?  SBS2011
    had DC, Exchange, RDS and Sharepoint,SQL, RemoteWebWorkplace, OWA all working in perfect harmony.  It is an untrue statement then, that it was "allowed but not recommended"
    Now you by Server2012 (core + two virtual) and its not enough for all this. 
    You need at least another $700 for another sever licence to have it all
    and who knows if SQL will run on a DC, or Exchange, or R-DERP server.  Another reacherous bridge to cross.
    By far, the absloute worse release since Millennium.  The product is not ready for production, we broke our rule of waiting until the first SP1 upgrade for this and Exchange 2013.  Problems with USB drivers and networking running extreamly slow. 
    Our 2003 SBS server was at least three times as fast, and this server has SAS and SSD drives running.  It can't get out of its own way, and IE10 is the most unstable piece of crap to come out of Redmond.  Open wide and swallow - Mother Microsoft
    knows whats best for you.  YOU WILL EAT OUR SLOP AND LEARN TO LIKE IT.   Server2012 AKA  "METRO-SERVER"
    Now here I sit after 50 Hours back to back setting up a new R-DERP server 2012, AD, Have my RDP licences in my hand at $100 each, and WTH does Microsoft care if I install it on my DC.  ITS MY DC.  And the cost savings versus the "risk" was
    previously MY decision. 
    Sure, I can install a couple of Virtual HyperV sessions but they are so tempremental to a power-outage in a small business its not worth it.  I have to double up my server hard drive resources, buy a $800 battery backup unit and make sure to attach
    the cable, and even then, if that Bi**H does not shut down properly, one bit goes awry in a VHD or VHDX file and you are screwed.  Restore from lastnights backup and forget about todays work.  Not to mention it will probably take a half day to try
    to fix it, then recover it then tell the 30 users they lost a days worth of work. 
    HYPER-V is for test servers and has no place in a small (micro) business environment. 5-30 users. 
    Microsoft's solution, buy another server.  Need Exchange?  Buy another server or take the risky cheapskate route and spin up some VHD's.  Might as well put a gun to your head and play russian roulette, at least you know you have a one in six
    chance of failure.  With MS, its a 100% failure for a dirty shutdown power loss, motherboard blows, memory goes corrupt in a few years, your conventional method of recovery is gone, and you have some upchucked VHD file to try to recover some of TODAYS
    data from. 
    Screw server 2012 forever. 
    I will sell 2008 and SBS2011 Premium unitl it rots in hell like XP (of which there is NOTHING wrong with for the average, WORD, EXCEL, OUTLOOK and QUICKBOOKS that all SMB's use.  Its MS $GREED$  Grab the world by the B**ls and squeeze with all
    your might to squeeze every dime you can out of *SMB* because big business is going to run thier 2003 Exchange and 2008 servers into ground before they switch to this garbage. 
    YOU CANNOT INSTALL EXCHANGE 2013 on DC , OR on R-DERP server. 
    Go buy another server license and server or MOVE TO THE CLOUD and get fleeced every month. 
    I have 30 DC/R-DERP/Exchange and SBS2011 Premium servers all running for years in perfect harmony, locked down with security so the users can't even WIGGLE with something they are not supposed to work with.  They get their apps, cannot install anything
    and all these servers are running just fine behind the firewall and perfectly save.  The track record of this combination is 100% stable and is up 24/7/365 with no problems.  Do yourself a favor and throw this 2012 into the river, you don't need
    any weights because it is LEAD and will sink to the bottom by itself.
    Why, you ask?  Official is "Its for your protection"  The real reason?  To sell you more $700 server licences.
    Maybe for SMB, we start selling Linux NAS Servers, host the Exchange in the cloud and be hearded like cattle to the Microsoft slaughterhouse.  One way or another, you are going to bleed.    A little each month to move to the cloud, or
    a small fortune if you want to have it in house.  Microsoft wants it to be more expensive to have in house.  No more buying a server and running it for six years before you upgrade.  They can't have in house servers competing with their cloud,
    and small businesses are the low hanging fruit  ripe for the pickin'. 

  • Windows 2012 Server Remote Desktop Virtualization + Linux Clients

    Hello!
    I wonder if anyone could shed a little light on this.
    We want to implement a Windows 2012 Server with Remote Desktop Virtualization for our office, which has around 12 users. Our company has its core apps developed in VB6.0, and those apps use MySQL as their database. We want clients to run Linux, which will
    have no other function than to connect and to Windows 2012 Server and display the remote session. Users need to work as usual, as they would in a local version of a Windows Desktop.
    Can this be done? If yes, is the Standard version of Windows 2012 Server the best to accomplish this?
    Thank you!

    Hi,
    Add to Tim, you need to acquire CALs for every user (About 12 in your case).

  • Synchronization fails on Windows 2012 Server

    Hello, Running DPM 2012 R2, Protected computer Windows 2012 Standard
            I'm backing up only folders (19 GB) on a Windows 2012 server which also have SCCM 2012 installed on it.  The initial replica and recovery point creations are successful.   Any
    scheduled synchronization job scheduled after will fail.    The job display "In progress" but there is 0 MB data transferred and will remain in that stage for days until I cancel the job.  A reboot of the protected server
    resolves the issue temporarily where I might get a couple days of successful synchronization\recovery points but then the job will freeze again.  I have looked in the event logs and the logs in Monitoring on the DPM server and also on the protected computer
    but have not found any error that points to the cause.  Has anyone seen this issue?  Will be grateful if someone can point me in the right direction of troubleshooting this issue.  Thank you.

    Got a window 2012 server build up. My root domain name looks something like corp.marketing   Well I seems to have missed to add the last .com or .local.  How do I add the .com to my existing root domain name please. The server is new, will
    go online in few days time. Thanks for all the help.

    I have a similar question and not sure if this is the right place. I had set a server with corp.brighterworld.com but the install wizard anywhere access had me believe that microsoft's strongly preferred domain name prefix was remote.brighterworld.com so
    I contacted GoDaddy and had it reissued as remote. but when I went to reconfigure for the new name. I had already set the server for being a CA, and in that process it issued like 4 or 5 certificates. So I had tried to rebuild the machine from scratch, but
    the it didn't wipe everything, but rather saved previous state which left the old certificate stuff to be dealt with. Any hints or help out here for us having to learn this stuff the hard way?
    Thanks,

    Hi,  
    We can use the active directory rename tools to rename domain NetBIOS name. But it is a complex and risky process.
    For more information about how to use random.exe to rename domain name, please refer to the following article:
    Rendom
    http://technet.microsoft.com/en-us/library/cc732097.aspx
    Besides, renaming of the NetBIOS domain name is not supported in any version of Exchange Server.
    For more information about this, the following threads can be referred to.

  • Installation of Exchange 2010 in Windows 2012 Server

    Hi all,
    We are planning to upgrade our current Exchange 2003 to Exchange 2010, Need some help on installation and Support of Exchange 2010 in Windows 2012 Server, as per the
    https://technet.microsoft.com/library/ff728623(v=exchg.150).aspx Exchange 2010 with sp3 is supported in Windows 2012 but I am unable to find the installer of Ex 2010 with sp3
    in web even in MSDN. There is only Ex 2010 with Sp1 available. I know that after installing ex2010 with sp1 version, I can install sp3 later but I found one link
    http://www.petenetlive.com/KB/Article/0000785.htm where it is mentioned that insllation can be done only after doing the registry settings.
    So is any one who has installed Ex 2010 in Windows 2012 Server and faced this issue and any solution.
    Thanks
    Mukesh

    You can easily install Exchange 2010 (SP3) on Windows Server 2012. If you are working with previous SP version’s you can easily upgrade after installing server. And registry settings
    are used to fix an error which may occur during migration, so it is not mandatory to correct registry settings each time during migration.
    You can find detailed information about installing Exchange 2010 (SP3) on Windows Server 2012 at this blog :http://oxfordsbsguy.com/2013/03/24/how-to-install-exchange-2010-sp3-on-windows-server-2012/
