ADPREP /forestprep RRS feed

  • Question

  • While attempting dcpromo I was informed that I would have to run ADPREP /forestprep form the ADPREP folder on the Install Disk.

    The forestprep WAS NOT inside the ADPREP Folder therefore:  No Forestprep to run

    Hi Richardsong,

    ·         Adprep/forestprep is a switch to be run from the command prompt in the schema master of a forest. You will not find forestprep inside the adprep folder because it is a switch.

    ·         ADPREP.exe is a command-line tool that extends the Active Directory schema, and updates permissions as necessary to prepare a forest and domain for a domain controller, that runs the Windows Server 2008 operating system.

    ·         The Adprep/forestprep command extends the schema objects that are necessary for the new features of windows server 2008.

    ·         You can find these extensions in the .ldf files of the \sources\adprep directory.

    ·         However ,look into the following links for more information
