Windows Server 2008 Domain RRS feed

  • Question

  • Hello,

    Actually I have one Windows Server 2008 (x86) domain controller with a functionnal forest in Windows Server 2008. I would like to add a new domain controller in Windows Server 2008 R2, do I need to upgrade my schema before or after I installed it. By the way for the beginning, I want to stay in a functionnal forest in Windows Server 2008 until I installed a second DC in W2K8 R2 and then I will probably upgrade my schema to W2K8 R2.

    Could you please tell me if it will work?

    Thanks.

  • Hi,

    yes, you have to upgrade your schema before using the first 2008 R2 DC in your domain. You can stay at the functional level until you won´t use features that needs the functional level.

    More info here:

  • Hi,

    You have to upgrade the schema and prepare it for Windows 2008 R2 but need not to do anything for Functional level at this moment.

    The Schema version for Windows 2008 R2 is 47

    Previous versions are

    13=Win2k
    30=2003
    31=2003R2
    44=2008

    The changes made by Windows 2008 R2 schema are as below

  • Yes, it's required to run it before you will promote new server as DC. If you wish you may follow this process with article on my blog at

    http://kpytko.wordpress.com/2011/08/25/adding-first-windows-server-2008-r2-domain-controller-within-windows-2003-network/

    This is for 2008 R2 in 2003 but works also for 2003. Do not change your Domain Functionsl Level/Forest Functional Level until you will have all 2008 R2 Domain Controllers.

  • Pls go through all the below articles.

    Windows Server 2008 R2 includes a 32-bit version and a 64-bit version of Adprep.exe. The 64-bit version runs by default. If you want  to run one of the Adprep.exe commands on a 32-bit computer, use the 32-bit version of Adprep.exe. It is called Adprep32.exe. In Windows 2008  R2, it is located in the \Support\Adprep folder.

  • Hi,

    To install a 2008 R2 DC you must upgrade your schema to version 47. Otherwise whenever you try to run dcpromo in your environment you will get an promot to run adprep /forestprep and adprep /domainprep and upgrade your schema.

    You d'nt need to change the functional level.

  • Hello,

    Actually I have one Windows Server 2008 (x86) domain controller with a functionnal forest in Windows Server 2008.

    Adding DC of windows 2008 R2 in windows 2008 DC environment requires upgrading of schema becasue schema version of 2008 is 44 where as Windows 2008 R2.

    do I need to upgrade my schema before or after I installed it. By the way for the beginning,

    You need to do prepare schema first using ADPREP & FORESTPREP, w/o preparing the schema of windows 2008, you can't add windows 2008 R2 DC's.

    I want to stay in a functionnal forest in Windows Server 2008 until I installed a second DC in W2K8 R2 and then I will probably upgrade my schema to W2K8 R2.

    There is no mandate to raise the DFL/FFL even though you have all the DC's in windows 2008 R2, but until you push the DFL/FFL you will not be able to get the benefits of win 2008 R2 like AD recycle bin, branch cache(requires win7 clients) etc. You can only raise the DFL when all the DC's are in windows 2008 r2 or DC's in other domain is 2008 R2 to raise the FFL. You can keep mix of windows 2008 & 2008 R2.

  • Thank you for all your answers.

    In my lab I have just one domain controller in Windows 2008 Server x86. Can I add a second domain controller with Windows 2008 Server x64? Do I need to make some change in the schema or something other?

     

    Thanks.

  • No not required. if you want to add windows 2008 r2 as an DC then only schema modification is required. The windows 2008 Schema version is 44 and 2008 R2 is 47. So you can run both the windows 2008 32 bit and 64 bit DC with schema version of 44 but not R2 version.

  • Every

    thing depends on that if that x64 is Windows Server 2008 R1 (schema version 44)

    If so, you can simply promote new server as DC without schema extension (it's one time process)

    But if you want to use Windows Server 2008 R2 (schema version 47) which is only 64 bitand it's completely new edition with its own schema fetures, you need to extend schema.

    Hello,

    I don't understand because you wrote that I can run both windows 2008 x86 & x64 with schema version 47 but not R2 version. So I need to prepare my schema first then or you made an error in your answer?

     

    Thanks.

  • Hi,

    this was a typo in his answer. With a schema version 47 you can also run windows server 2008 r2.

  • My bad, it was a typo error, i have corrected it. The conclusion is yes you can run run windows 2008 X64 with windows 2008 x32 DC already been running without requiring to modify schema or any other settings.

    Thanks Martin, i guess i need a coffee now to make myself awake...:)
