Best practice for joining a Server2008R2 in 2003 domain

Posted on 2012-09-19
Last Modified: 2012-09-24
I have just purchased a new 2008R2 server and need to join this to my existing Server 2003 domain.
I think to recall that there was a few traps here after running the /DOMAINPREP /FORRESTPREP.

Can anyone please give me a hint.

    First question,

    1 . will you be using this windows server 2008 R2 as a domain controller? IF yes , you need to perform the ADPREP Operations on you active directory domain,

      WIndows server 2008 R2 comes up with 64 bit (No 32 Bit) , so while running the ADPREP you need to choose appropraite ADPREP and run the commandline on respective FSMO mentioed below.

    Command                                                        Domain Controller
    adprep.exe /forestprep                                   Schema Master
    adprep.exe /domainprep                                 Infrastructure Master
    adprep.exe /domainprep /gpprep                   Infrastructure Master
    adprep.exe /rodcprep *                                   Domain Naming Master

    Reference -

    You can skip RODC if you dont have the Readonly domain controller in your environment.

    Once all of the above commandline have been run respectively FSMO Holder domain controller , you can introduce the new windows server 2008 R2 as domain controller.

    Note - These commandline will upgrade the schema , add the Security ACL etc , If you need to understand what they do , follow below link

    Below are some more links to carry out the tasks

    2. If you are joining the windows server 2008 R2 to the domain (Not as a domain controller , but as the member server) then above steps you can ignore.

    Hope this helps
