Domain Functional Level: 2008 R2 to 2012 R2

My current forest and domain functional levels are 2008 R2. I know I can safely upgrade the functional levels in most cases, but I want to specifically know with regards to Lync.
Our entire environment, including Lync, is running on Windows Server 2012 R2. (We have no domain joined clients.)
Can I safely raise the forest and domain functional levels to 2012 R2 without impacting Lync?

you can easily upgrade the funtional level without any issues since you have all the Domain Controllers on Win server 2008R2.

  • What is the effect if I Raise my domain functional level to Windows Server 2012 R2 ?

    Hi,
    my current servers:
    Domain Controllers= Windows Server 2012 R2 (current domain functional level is windows 2008 R2)
    Mail servers= Exchange 2010 SP3 on Windows 2008 R2
    Lync= Lync 2010 on Windows server 2008 R2
    What is the effect if I Raise my domain functional level to Windows Server 2012 R2 ?
    I am very worried about Exchange & Lync if we do this action
    please advice

    Do not raise the forest functional level higher if you have or will have any domain controllers running
    an earlier version of Windows Server , which is (windows Nt4.0,  Window 2000 or windows 2003)
    but as a matter of fact I dont see any of those in your network so you can easily upgrade the funtional level without any issues

  • Lync 2013 and Raising Forest/Domain Functional Level?

    My current forest and domain functional levels are 2008 R2. I know I can safely upgrade the functional levels in most cases, but I want to specifically know with regards to Lync.
    Our entire environment, including Lync, is running on Windows Server 2012 R2. (We have no domain joined clients.) We are running Lync 2013 Standard with all the latest updates.
    Can I safely raise the forest and domain functional levels to 2012 R2 without impacting Lync?

    Hi,
    Yes, you can raise Forest and domain function level to Windows Server 2012 R2 without issue.
    After raising Forest\domain function level, the new features that rely on the functional level are generally limited to AD itself. Regardless, changing the Domain or Forest Functional Level should have no impact on an application that depends on
    Active Directory.

  • Cannot Replicate after upgrading domain functional level

    Hello, 
    Parent and child domain. Parent domain (forest) still in domain functional level 2003. However, child domain i just updated to domain functional level 2008 R2. Now replication is not working. I believe the issue is dns, but i do not know what could be different
    the names have not changed? This is a two way transitive trust between domains.
    Frequent messages from dcdiag dns, are 
    no DNS RPC connectivity (although i have tried restarting dcom, netbios and frs)
    Also in event viewer many 13508 errors
    Any help is greatly appreciated thank you.

    Have you restarted the DCs after that you raised the functional level? The password of the krbtgt account is reset when the DFL is raised from 2003 -> and sometimes the DCs need to be restarted for the authentication to succeed up to the root.
    If you from a Windows Server 2008 R2 DC run dcdiag /test:dns /E dose it report any errors?

  • SCSM 2012 with 2003 domain functional level supported?

    All,
    I am running SCCM 2007. Now I need to install Service Manager 2012SP1. Domain functional level is 2003 with 2008 DC.
    will this allow me to install SCSM 2012SP1 with full features? or will it be reduced functionality?
    will there be any schema extension when I install SCSM 2012? pleas note we already have SCCM 2007 running.
    can I upgrade SCCM 2007 to SCCM 2012?  
    it would be helpful if you could share some link about whether its possible or not.
    Thanks.
    KailashC

    Thomas,
    Thanks for your response. Can I do a direct upgrade SCCM 2007 SP3 to SCCM 2012 or do I need to plan a migration? I mean fresh install SCCM 2012 and then migrate the data over ?
    Thanks.

  • Missing nodes in new GPO objects after adding ADMX to DC (Server 2008 Domain Functional Level 2003)

    Hello,
    we discovered an issue in GPO console.
    DCs: multiple 2008 there is one 2003DC somewhere over the rainbow (don't ask why) :)
    Domain Functional Level is 2003.
    In June I added Policydefinitions folder into Policy folder in sysvol\domain_name.
    I did this for adding ADMX.
    Today we found missing nodes when adding new GPO objects and trying to modify them.
    Under Computers\Administrative Templates there is only ADMX node. No Administrative Templates with sub nodes: Systeme, Network, Printes, Windows Components.
    When edit old GPOs There is Administrative Templates in Administrative Templates with ADMX folder. SEE Screenshot.
    My colleague insists that it happened after I made changes by adding ADMX things. Looks that he is right.
    Please any help on this issue... How to get back nodes for managing new GPOs as it was before adding ADMX.
    Is this something known? I didn't find any prerequisites before adding PolicyDefinistions folder.
    Thanks.
    "When you hit a wrong note it's the next note that makes it good or bad". Miles Davis

    Meinolf,
    1. I would like to know if it is normal behaviour that after creating a Central Store (adding PolicyDefinitions folder into Policies) Classical Administrative Templates will not appear for any new GPO (they do exist to all previously created) see
    picture
    2. I followed the links. And eventually will use the script for cleaning up duplicate adms  in all GPOs. It is great feature of ADMX. But first I would like to bring back the option of Admin Templates.
    So I downloaded latest 2012 ADMXs. Run setup on my computer. Now I have Policydefinitions folder containing new ADMXs with languages (culture) folders.
    Am I right? I have to copy all *.admx files to my Central Store Policydefinitions folder and all En admls drop to En-Us language folders. What will happen if I will add Fr-Fr? Would it be correct to have 2 languages for the same admxs. And how they will
    appear. Or it will depend on OS language were GP console will be opened?
    No conflict to expect?
    I will do this "surgery" after your answer.
    Thanks for pointing out..

  • Domain functional level upgraded to 2008 r2 native mode but query states 2003

    Nothing :(

    I raised the domain functional level last night to 2008 r2 native mode and after allowing everything to sync i ran the command get-addomain .domainmode and it came back ast windows2003forest. 
    I dont understand why it is showing up this way, we removed all of the 2003 domain controllers and server from our network before doing this...Any suggestions?

  • AD FS Across Differing Domain Functional Levels

    My customer needs to implement AD FS for single sign on due to a cloud based email solution they recently implemented. The problem is, their domain controllers are Server 2003 (non-R2) at a functional level of 2003 mixed mode. They should be able to raise
    to 2003 native if necessary however. Their solution is to create a new 2008 domain and implement a two-way trust, running AD FS in the new domain serving the clients in the 2003 domain.  This way should be quicker than upgrading their current domain
    which would be a rather large project due to their size and complexity. 
    Are there any gotcha's I should know about with doing it this way?  I have verified that we can create the two-way trust between domains of these functional levels, and AD FS can service clients in a trusted domain, but I am not entirely sure if AD
    FS will care that the trusted domain is 2003 non-R2.  Can anyone confirm if this will be a feasible scenario? 
    Thanks very much!!
    Wraith

    Hi
    Wraith,
    In addition, if you are not using Windows Server 2012 or above as ADFS server, you will be fine with Windows 2003 mixed mode.
    “Since ADFS does not require Active Directory functional-level modifications to operate successfully. However, if you are using Windows NT token–based applications and
    you want a token to be generated using Kerberos Service-for-User (S4U), the domain functional level must be Windows 2000 native or Windows Server 2003”, quoted form below article:

  • Error Domain functional level

    Hi i have that error in my Domain Controller. Install Windows
    Server 2012 R2, and I want to raise the functional level.
    This Domain Controller no longer exists,
    but is within the domain.
    To update the domain functional level, the Active Directory Domain Controllers in the domain must be running the appropriate version of windows.
    domain Name
    xxxxxx.local
    Current domain functional level
    Windows Server 2008
    The following Active Directory Domain Controllers are running earlier versions of windows:
    domain Name    AD DC    Version of Windows
    xxxxxxx.local    server.xxxxxx.local    Windows Server® 2008 Standard 6.0 (6001)
    that I can
    do?

    it might be in the "LostAndFoundConfig" container in the Configuration partition.
    Something like this should be logged:

  • CRM2015: AD Domain Functional Levels Ambiguity - Clarification Sought

    In the Planning and Deployment guide (page 17) It states.
    The domain where the server is located must be running in one of the following Active Directory domain functional levels:
    Windows Server 2008 Modes
    Windows Server 2008 R2 Modes
    Windows Server 2012 Modes
    For more information about Active Directory domain and forest modes, see:
    Understanding Active Directory Domain Services (AD DS) Functional Levels
    Active Directory (Windows Server 2012 R2)
    Windows 2000 Server forest and domain modes are not supported with this version of Microsoft Dynamics CRM.
    When it states Windows Server 2008 Modes, does it mean only 2008 modes, or the modes supported by 2008. As I believe one of the 2008 Modes is 2003 Native and Interim.
    Can anybody confirm if AD controllers must be 2008 or higher to support CRM?

  • Unable to Raise domain functional level

    I am installing a Server 2012 std.  in a single domain. The current DC is Server 2008 std. When I try to raise the domain functional level to at least 2003 it gives me an error.
    I did the save as and viewed the error message.  Apparently some time in the past they had a Server 2000 and active directory still has the entries that is preventing the domain from being raised.  I removed the old server from AD CU and restarted
    the server.  Still will not let me raise the level, same error.  Do I need to use ADSI edit and remove all the entries also?  What about DNS entries?
    Thank you for a rapid answer.

  • Windows 8.1 Clients cant register record in DNS in forest functional level 2008 environment (DNS Client Events 8018)

    Hello,
    I have two DC,:
    first Windows Server 2008, second Windows Server 2012 R2,
    AD works in forest functional level 2008
    Workstations working in Windows 8.1 OS cant register to DNS with warning:
    The system failed to register host (A or AAAA) resource records (RRs) for network adapter
    with settings:
               Adapter Name : ...................................................
               Host Name : ...................................
               Primary Domain Suffix : ....................................
               DNS server list :
               Sent update to server : <?>
               IP Address(es) :
    The reason the system could not register these RRs was because the DNS server contacted refused the update request. The reasons for this might be (a) you are not allowed to update the specified DNS domain name, or (b) because the DNS server authoritative for
    this name does not support the DNS dynamic update protocol.
    To register the DNS host (A or AAAA) resource records using the specific DNS domain name and IP addresses for this adapter, contact your DNS server or network systems administrator.

    Hi,
    Functional levels determine the available Active Directory Domain Services (AD DS) domain or forest capabilities. They also determine which Windows Server operating systems you can run on domain controllers in the domain or forest. However, functional levels
    do not affect which operating systems you can run on workstations and member servers that are joined to the domain or forest. Set the domain and forest functional levels to the highest value that the environment can support, in order to use as many AD DS features
    as possible.
    You may reference SenneVL’s suggestion, and use ipconfig /registerdns
    on the workstation to confirm that if the DNS record can be registered.
    Best Regards,
    Eve Wang

  • Raising Domain Functional level

    We have 75 domain Controllers in our Org and current Domain Functional level is 2003. We have a mix setup where all versions of OS are available starting from 2003. A large no of applications are also integrated with our current Active Directory.
    My concern is, If I raise my Domain Functional level to 2008 then what are the consequences we might face in terms of accessing legacy applications.
    Please let me know the checklist which we need to follow and incase of any failure then what will be the rollback procedure.
    Looking forward for your valuable inputs. 

    Hi, 
    I agree with others. Once the Functional Level has been upgraded, new
    servers running on lower versions cannot be added
    as Domain Controllers to the domain or forest. If all the DCs in the domain is server 2008 and later version, we can raise the function level of the domain to get more advanced features.
    > If I raise my Domain Functional level to 2008 then what are the consequences we might face in terms of accessing legacy applications.
    For this question, make sure that the applications in the domain are compatible with the new functional level

  • Why domain functional level should be greater than or equal to forest FL?

    We know that domain functional level must be greater than or equal to forest functional level. Why is that so?
    My perspective is if we set FFL to windows server 2008 r2 and DFL to windows 2003, active directory recycle bin won't be available to the domain whose FL is windows 2003. Is that right?

    Greetings!
    Active Directory Recycle Bin needs to be implemented in a forest with 2008 R2 forest functional level. Because it was added in 2008 R2 operating system. In order to have a 2008 R2 forest functional level you need to raise all the child domains DFL's first.
