Add Windows Server 2012 R2 domain controller to Windows 2008 R2 domain

Hi,
Have today 2 x Windows Server 2008 R2 domain controllers, and domain and functional level 2008 R2.
We now want to replace these DC`s with Windows Server 2012 R2.
My plan is as follow
- Install and promote a Windows Server 2012 R2 as a 3 DC`s with a temporary hostname and IP as DC3
- Install and promote a second Windows Server 2012 R2 as a 4 DC`s with a temporary hostname and IP as DC4
- Decomiss DC1 and remove this host. Change the IP and hostname of the new DC3 to DC1
- Move FSMO roles from DC2 to DC1 and decomiss DC2
- Change the IP and hostname of the new DC4 to DC2
Will this be a ok progress ? I will offcours to have the DC`s replicate information between them before doing each task.
/Regards Andreas

Hi,
Only error i got running dcdiag was the following
 Starting test: NCSecDesc
    Error NT AUTHORITY\ENTERPRISE DOMAIN CONTROLLERS doesn't have
       Replicating Directory Changes In Filtered Set
    access rights for the naming context:
    DC=ForestDnsZones,DC=domain,DC=local
    Error NT AUTHORITY\ENTERPRISE DOMAIN CONTROLLERS doesn't have
       Replicating Directory Changes In Filtered Set
    access rights for the naming context:
    DC=DomainDnsZones,DC=domain,DC=local
    ......................... DC1 failed test NCSecDesc
Is this a problem ?
I would guess not since im not implementing a RODC ? Ref:

  • Unable to add network printers from Windows Server 2012 R2 to client running Windows 7 Pro x64

    New Windows Server 2012 R2 Standard in the environment.  Added print services to it and added five HP printers to it and shared them.  Also deployed the printers via group policy.
    Clients are running Windows 7 Pro x64.  The group policy fails to install the printers (error 0x00000002).  We get the same error when trying to manually add the printer from the client side.
    From Event Viewer: Group Policy was unable to add per computer connection <<printer share>>. Error code 0x2. This can occur if the name of the printer connection is incorrect, or if the print spooler cannot contact the print server.
    Any ideas on troubleshooting this?
    Thanks.
    -John

    John,
    You might try playing with the HP universal driver, that might help you.  Try installing a new shared printer on the server using the universal print driver, then try and connect to it to see if it is any better.
    Check these GPO settings to ensure local machines can install the drivers.
    1. Configure the following two Group Policy settings:
    Computer Configuration\Policies\Administrative Templates\System\Driver Installation\Allow non-administrators to install drivers for these devices setup classesEnabled
    2. Device class GUID of printers: {4d36e979-e325-11ce-bfc1-08002be10318}

  • Windows Server 2012 CA will not allow Windows XP to autoenroll

    I have a Windows Server 2012 Domain Controller with an Enterprise root CA installed.  I have created a client authentication certificate template (2003 compatible).  Domain Computers have Read, Enroll and Autoenroll permissions.  I modified
    the Domain Policy to enable Certificate autoenrollment.  I have two clients on the same subnet with the domain controller, one Windows 7 Ent SP1 and one Windows XP SP3.  The problem:  Windows 7 reboots, has client auth cert installed in computer's
    personal cert store.  The Windows XP machine cannot acquire the certificate.  Event ID 13, source is AutoEnrollment, 0x80094011,The permissions on this certification authority do not allow the current user to enroll for certificates.  Both machines
    belong to the domain.  Running gpudate /force on the XP machine generates an info event stating that the computer security policy has be applied successfully, then the autoenrollment error.  I've setup autoenrollment dozens of times without any
    problems.  The only thing different in this environment is that the CA is installed on Server 2012.  I could be something else, but the only real difference is Server 2012.  There are no errors on the server.  It is like the client just
    cannot talk to the server at all, but it's getting its policy from that server.
    Any ideas? 

    http://technet.microsoft.com/en-us/library/hh831373.aspx
    What works differently?
    Windows XP clients
    will not be compatible with this higher security setting enabled by
    default on a Windows Server 2012 CA. If necessary, you can lower the
    security setting as previously described.
    Try run this command:
    certutil -setreg CA\InterfaceFlags +IF_ENFORCEENCRYPTICERTREQUEST
    Restart the certification authority
    net stop certsvc
    net start certsvc
    INFO FROM LINK:
    What value does this change add?
    The CA
    enforces enhanced security in the requests that are sent to it. This
    higher security level requires that the packets requesting a certificate
    are encrypted, so they cannot be intercepted and read. Without this
    setting enabled, anyone with access to the network can read packets sent
    to and from the CA using a network analyzer. This means that
    information could be exposed that might be considered a privacy
    violation, such as the names of requesting users or machines, the types
    of certificates for which they are enrolling, the public keys involved,
    and so on. Within a forest or domain, leaking these data may not be a
    concern for most organizations. However, if attackers gain access to the
    network traffic, internal company structure and activity could be
    gleaned, which could be used for more targeted social engineering or
    phishing attacks.
    The commands to enable the enhanced security
    level of RPC_C_AUTHN_LEVEL_PKT on Windows Server®  2003,
    Windows Server®  2003 R2, Windows Server®  2008, or Windows
    Server 2008 R2 certification authorities are:
    certutil -setreg CA\InterfaceFlags +IF_ENFORCEENCRYPTICERTREQUEST
    Restart the certification authority
    net stop certsvc
    net start certsvc
    If
    you still have Windows XP client computers that need to request
    certificates from a CA that has the setting enabled, you have two
    options:

  • Windows Server 2012 Used: Error Message from Windows 7 PC: Remote session was disconnected because there are no remote desktop license servers available to provide a license. Please contact the server administrator.

    We are using Windows Server 2012 Standard installed in VMWare / Virtual machine and to access this we use vSphere client and Remote Desktop Connection / service was already enabled and was working fine with User PCs / laptops remote desktop into the server
    2012, until it gave an error message of: Remote session was disconnected because there are no remote desktop license servers available to provide a license.  Please contact the server administrator. whilst logging into the server. 
    We DON'T use Active Directory nor and we don't use domain and not looking to use it any-time soon. 
    I checked the RD Licensing Diagnoser and it says the grace period has expired and the licensing mode for the remote desktop session host server is not configured.  I have checked the Remote Desktop Gateway has been stopped and I tried to start it and it
    resumed to stop, here I assume its where the licensing part comes in to re-enabled this. 
    I have been trying to follow these articles online: http://ryanmangansitblog.com/2013/03/27/deploying-remote-desktop-gateway-rds-2012/ and http://www.concurrency.com/blog/rds8-add-a-licensing-server-2/#Install  the overview part that I cannot get into,
    because I think we have to be is AD DS for this which we don't.  Is there a way around this for non domain / just standalone set-up?  Is it a must / requirement we need to be in a domain in order for Remote Desktop Connection to work? 
    Also, we have a Windows Server 2012 RDS CALs - 10 (software and licence key), will the licence key work for the Windows 2012 Server Standard?  We do not want to install the other Server mentioned which comes with CAL / licence key as its time consuming
    to reinstall other programs.  I have installed  Server role service of Remote Desktop Licencing and automatically installed other associated services needed.  in the RD Licencing Manager, the Server had a red cross and I "Activate Server"
    where I followed: http://www.concurrency.com/blog/rds8-add-a-licensing-server-2/#Install in Install Licences section and I have used the licence key of CAL - 10 mentioned above; it stated I have successfully completed the install licences wizard and displayed:
    10 Windows Server 2012 - RDS Per User CAL installed, and in the RD Licensing Manager the server turned into a green tick and added the licence.  
    I then tested the Remote desktop connection from my PC and the same error message was there and checked the RD Licensing Diagnoser and the same error messages was there.  I haven't restart the services of Remote Gateway / the server itself; do I really
    need to reboot server?  
    Any advice / guidance would be very much appreciated and this is a urgent matter.  
    Thank you for your time.

  • WIndows Server 2012 w/ Hyper V and Windows 7

    I have been able to create every imaginable virtualization in a test environment except for Windows 7. It asks for drivers. I have a driver CD but when I put the CD in the D: drive. It will run but suddenly the command line screen states that a file on

    I might have misstated my situation. I have Windows Server 2012 outfitted with Hyper-V. I'm trying to virtualize a Windows 7 operating system.
    I found a another W7 media disk that seems to bypass this problem.

  • Get server with Windows Server 2012 R2 or wait for Windows Server "10"?

    We are looking to get a new server this year but with Windows 10 coming out shortly/this year, wouldnt it be better to wait until Windows Server "10" is released THEN get the server?
    Thank you

    Hi,
    Windows 10 is the next version of the Windows client operating system. Until now, there is no official information of Windows Server operating system about the version next to Windows Server 2012 R2. You may pay attention to Microsoft official website for
    the information about the newest product.

  • Using Windows Server 2012 VL Product key with Windows Server 2012 R2

    Hi all,
    Trying to use a Server 2012 vl product key to active a Server 2012 R2, but running into issues, namely it is not accepting the key. I have read many threads pointing out that different keys are required, but no mention of the process that one needs
    to take in order to obtain/swap product keys? Any ideas appreciated? :)

    The product key I have is for Windows Server 2012 Standard VL, (It's not a DC).
    I have downloaded the evaluation iso for Windows Server 2012 R2 and want to licence it (with a VL), but it is failing with the Windows Server Standard 2012 VL product key.
    My question is - am I doing something wrong, or do I need to ask Microsoft to change the product key / buy a new one? - What steps do I need to take?
    The product key for WS2012 will not work for WS2012R2. (so, yeah, you're doing that wrong)
    WS2012R2 is not a "free" upgrade from WS2012 (it's different to Win8.0 -> Win8.1)
    Your WS2012 pkey will work with WS2012. To use WS2012R2 you need a WS2012R2 pkey.
    If you want to "convert" an evaluation license install, into a full licensed install, you must match the version (2012 vs. 2012R2) and the edition, and must use DISM as well as the correct pkey.
    http://technet.microsoft.com/en-us/library/jj574204.aspx
    If you don't have the correct pkey for WS2012R2 already, and you don't have one waiting for you in the Volume Licensing Service Center website, you'll need to purchase a new license for WS2012R2.

  • Windows Server 2012 R2 Hyper V on a SBS 2011 Domain replication failure

    I have a SBS 2011 Domain which I am adding two 2012 R2 Standard servers in order to facilitate virtualization and consolidate physical servers. I have the two 2012 R2 servers up and running and a test server running virtually on Hyper-V.   I want
    to test replication from one Hyper-V host to the other, however, I am unable to setup Kerberos delegation in the SBS 2011 AD domain.  Specifically, the Service Type of Microsoft Virtual System Migration Service is not listed.  CIFS is available,
    however, there are no Service Types having to do with Hyper-V available.
    I have upgraded the AD using adprep from the 2012 R2 installation disc, however, this has not added the service types.
    Thank you in advance for the help!

    Hi Justin,
    Thank you for the information.  I had originally reviewed the article you mentioned in your reply, however, this did not work for me.  It accurately described the problem I am having, however, the solution did not work.
    I did a little review of the syntax of the command SETSPN and found that the article referenced above has a "/" instead of a "\" in the command line.  When I modified my syntax to reflect using the forward slash, the command seemed to processed
    correctly, however, when I go back to the delegation steps, the service name is still not there.  I did verify the service was registered properly by listing out all the SPN registrations.
    Clarifying Question:  Based on the command I ran to add this Service, I am wondering if I used the correct servers.  Basically, I have the following:
    Server 1 - SBS 2011 domain controller
    Server 2 - 2012 R2 Hyper-V Server
    Server 3 - 2012 R2 Hyper-V Server
    I want to setup this Kerberos delegation for CIFS and Microsoft Virtual System Migration on Server 2 and 3 and am setting this up using ADUC on Server 1.  I ran the SETSPN command on Server 1 for Server 1 - was this the correct thing to do or should
    I have an SPN entry for Server 2 and/or 3?
    Sorry for what is probably a very basic question.
    Thank you again for your help.

  • Renaming Windows Server 2012 Domain Controller with Exchange Server 2013

    Is it possible to rename Windows Server 2012 Domain Controller, as we are using Exchange Server 2013 as a member server on Windows Server 2012 ?
    We have some issues with the Domain Name, so want to rename..
    Maybe somebody knows the best practices how to do this in best way???
    Thanks.

    Hello,
    You should do the following:
    1. Promote another DC.
    2. Transfer FSMO roles to that server.
    3. Decommission old DC.
    4. Rename it.
    5. Promote it again as DC.

  • Using Windows Server 2012 per-User RDS CAL on Server 2008 R2 Session Host

    I have a Remote Desktop Licensing Server setup on my domain controller running Windows Server 2012 R2. I have installed a
    ’Windows Server 2012 Remote Desktop Services per-User CAL’ there and activated the licensing server already.
    Currently I use ONLY Windows Server 2008 R2 machines as RDS Session Hosts (in the future I plan to transition them to 2012 R2, hence the CAL I bought is
    already in the newest version).
    I have already configured my WS 2008 RDS Session Hosts: set
    Per-User licensing mode and specified license server address. The connectivity between my Session Host(s) and my License Server seems to be ok as the
    Remote Desktop Session Host Configuration window on the Session Host correctly lists the 2012 per-user
    license (CAL installed on server) from the license server.
    On the License Server I can also see event logs entries (in
    Microsoft-Windows-TerminalServices-Licensing/Admin), indicating that the user has been issued a license.
    The issue I am having is that the license being issued is
    2008 Per User CAL license (Build-in OverUsed - temporary) and not the 2012 Per User CAL license which is the only license installed on the server. According to the RDS CAL interoperability matrix at
    social.technet.microsoft.com/wiki/contents/articles/14988.rds-and-ts-cal-interoperability-matrix.aspx, I was expecting the 2012 license to be backward-compatible with 2008 client (and that
    in the absence of legacy licenses, the (only) 2012 license would be used for all clients connecting to the licensing server)
    Before I bought my license, I found this document: 
    download.microsoft.com/download/3/D/4/3D42BDC2-6725-4B29-B75A-A5B04179958B/WindowsServerRDS_VLBrief.pdf 
    which says that - "newer version RDS CALs can be used with an older version of the server software" (In section FAQ, Q4), which means to me that
    the 2012 license would work as-is for the 2008 Server and gives me flexibility when upgrading to the new server version.
    How can I make this CAL work in my environment? 
    Note:
    I have already explicitly disabled
    Prevent license upgrade Group Policy setting which I assumed would fix the issue but nothing has changed.
    Then I have enabled License server security group Group Polity setting
    and added computers from my domain to RDS Endpoint Servers AD group. I have also created new AD group called
    Terminal Server Computers and added the computer accounts there, but it changes
    nothing. Reference - technet.microsoft.com/en-us/library/ee791761.aspx , technet.microsoft.com/en-us/library/cc725704.aspx and blogs.msdn.com/b/rds/archive/2009/09/17/control-the-issuance-of-rds-cals.aspx.
    I found one potential ‘workaround’ which involved manually downgrading my CAL license by calling
    Microsoft Clearinghouse. I am very reluctant do to so because, as I upgrade parts of my infrastructure to Server 2012, I’d need to then ask Microsoft to manually upgrade a part of my license back as well.
    Am I missing something? What should I do to get my 2012 CAL to be issued to 2008 R2 server

    Hi, I have tried several other possibilities.
    I change expire date for my temporary assigned license (2008 CAL overused). It can be done, by changing Active Directory user properties – msTSExpireDate. When I restart my Session Host server and logged again, my license was renewed
    for next 60 days (event ID - 4145).
    I also delete information about license for this user (clear msTSExpireDate and msTSLicenseVersion). And the license was successfully removed from License Manager. After another SH restart it gets the same – 2008 overused – license
    (event ID 4143 - license server has successfully issued …)
    I now, that changing info in AD attributes is a little trick, and this is not a real value - only a reference, but it was useful to delete or change expiration date of license. But it didn’t change type of license as I expected.

    To TP:
    I have found your post with information:
    If you have a Server 2012 RD Licensing server you may install your 2012 RDS CALs on it (no downgrade necessary) and then set your Server 2008 R2 RDSH to
    use the 2012 RDL server.  The 2012 RD Licensing server will automatically issue the CALs as 2008. -

    And it showing my situation in brief. I also found
    similar problems, but the solutions don’t meet my expectations.

    – “this should go away after a while”
    Is there a way to determine this time you mentioned before? Or should I just wait patiently…
