Hello,

I want to add a domain controller (Windows Server 2008) to an existing domain (domain on Windows Server 2003). When I follow the Active Directory installation steps, it shows me the following message: "failed to examine the active directory forest the error was expected value ridmasterdsa.parentDN not found"

RQ: I have a Dell PowerEdge 2800 as a server equipped with Windows Server 2008 R2

Any idea.

Thank you.

    Do not perform this operation in a production environment. You must first do it in a test environment!

    have you done the adprep?
    if yes, did you use the 32-bit version on the Windows 2008 R2 DVD?

    Some pointers:

      Hi
      I tried to run adprep on the CD "Windows Server 2008 R2 64-bit", but it doesn't work.
      Thanks

      You have to choose the 32-bit version
      what error message do you get?

      when I run "adprep32 /forestprep" it shows the following message:
      Adprep cannot run on this platform because it is not an Active Directory
      Domain Controller.
      [Status/Consequence]
      Adprep stopped without making any changes.
      [User Action]
      Run Adprep on a Active Directory Domain Controller.
